NAME

       crm - Pacemaker command line interface for configuration and management

SYNOPSIS

       crm [OPTIONS] [SUBCOMMAND ARGS...]

DESCRIPTION

       The crm shell is a command-line based cluster configuration and
       management tool. Its goal is to assist as much as possible with the
       configuration and maintenance of Pacemaker-based High Availability
       clusters.

       For more information on Pacemaker itself, see http://clusterlabs.org/.

       crm works both as a command-line tool to be called directly from the
       system shell, and as an interactive shell with extensive tab completion
       and help.

       The primary focus of the crm shell is to provide a simplified and
       consistent interface to Pacemaker, but it also provides tools for
       managing the creation and configuration of High Availability clusters
       from scratch. To learn more about this aspect of crm, see the cluster
       section below.

       The crm shell can be used to manage every aspect of configuring and
       maintaining a cluster. It provides a simplified line-based syntax on
       top of the XML configuration format used by Pacemaker, commands for
       starting and stopping resources, tools for exploring the history of a
       cluster including log scraping and a set of cluster scripts useful for
       automating the setup and installation of services on the cluster nodes.

       The crm shell is line oriented: every command must start and finish on
       the same line. It is possible to use a continuation character (\) to
       write one command in two or more lines. The continuation character is
       commonly used when displaying configurations.

OPTIONS

       -f, --file=FILE
           Load commands from the given file. If a dash - is used in place of
           a file name, crm will read commands from the shell standard input
           (stdin).

       -c, --cib=CIB
           Start the session using the given shadow CIB file. Equivalent to
           cib use <CIB>.

       -D, --display=OUTPUT_TYPE
           Choose one of the output options: plain, color-always, color, or
           uppercase. The default is color if the terminal emulation supports
           colors. Otherwise, plain is used.

       -F, --force
           Make crm proceed with applying changes where it would normally ask
           the user to confirm before proceeding. This option is mainly useful
           in scripts, and should be used with care.

       -w, --wait
           Make crm wait for the cluster transition to finish (for the changes
           to take effect) after each processed line.

       -H, --history=DIR|FILE|SESSION
           A directory or file containing a cluster report to load into the
           history commands, or the name of a previously saved history
           session.

       -h, --help
           Print help page.

       --version
           Print crmsh version and build information (Mercurial Hg changeset
           hash).

       -d, --debug
           Print verbose debugging information.

       -R, --regression-tests
           Enables extra verbose trace logging used by the regression tests.
           Logs all external calls made by crmsh.

       --scriptdir=DIR
           Extra directory where crm looks for cluster scripts, or a list of
           directories separated by semi-colons (e.g.  /dir1;/dir2;etc.).

INTRODUCTION

       This section of the user guide covers general topics about the user
       interface and describes some of the features of crmsh in detail.

   User interface
       The main purpose of crmsh is to provide a simple yet powerful interface
       to the cluster stack. There are two main modes of operation with the
       user interface of crmsh:

       ·   Command line (single-shot) use - Use crm as a regular UNIX command
           from your usual shell.  crm has full bash completion built in, so
           using it in this manner should be as comfortable and familiar as
           using any other command-line tool.

       ·   Interactive mode - By calling crm without arguments, or by calling
           it with only a sublevel as argument, crm enters the interactive
           mode. In this mode, it acts as its own command shell, which
           remembers which sublevel you are currently in and allows for rapid
           and convenient execution of multiple commands within the same
           sublevel. This mode also has full tab completion, as well as
           built-in interactive help and syntax highlighting.

       Here are a few examples of using crm both as a command-line tool and as
       an interactive shell:

       Command line (one-shot) use:.

           # crm resource stop www_app

       Interactive use:.

           # crm
           crm(live)# resource
           crm(live)resource# unmanage tetris_1
           crm(live)resource# up
           crm(live)# node standby node4

       Cluster configuration:.

           # crm configure<<EOF
             #
             # resources

             #
             property stonith-enabled=true
             commit
           EOF

       The crm interface is hierarchical, with commands organized into
       separate levels by functionality. To list the available levels and
       commands, either execute help <level>, or, if at the top level of the
       shell, simply typing help will provide an overview of all available
       levels and commands.

       The (live) string in the crm prompt signifies that the current CIB in
       use is the cluster live configuration. It is also possible to work with
       so-called shadow CIBs. These are separate, inactive configurations
       stored in files, that can be applied and thereby replace the live
       configuration at any time.

   Tab completion
       The crm makes extensive use of tab completion. The completion is both
       static (i.e. for crm commands) and dynamic. The latter takes into
       account the current status of the cluster or information from installed
       resource agents. Sometimes, completion may also be used to get short
       help on resource parameters. Here are a few examples:

           crm(live)resource# <TAB><TAB>
           bye           failcount     move          restart       unmigrate
           cd            help          param         show          unmove
           cleanup       list          promote       start         up
           demote        manage        quit          status        utilization
           end           meta          refresh       stop
           exit          migrate       reprobe       unmanage

           crm(live)configure# primitive fence-1 <TAB><TAB>
           heartbeat:  lsb:    ocf:    stonith:

           crm(live)configure# primitive fence-1 stonith:<TAB><TAB>
           apcmaster                external/ippower9258     fence_legacy
           apcmastersnmp            external/kdumpcheck      ibmhmc
           apcsmart                 external/libvirt         ipmilan

           crm(live)configure# primitive fence-1 stonith:ipmilan params <TAB><TAB>
           auth=      hostname=  ipaddr=    login=     password=  port=      priv=

           crm(live)configure# primitive fence-1 stonith:ipmilan params auth=<TAB><TAB>
           auth* (string)
               The authorization type of the IPMI session ("none", "straight", "md2", or "md5")

       crmsh also comes with bash completion usable directly from the system
       shell. This should be installed automatically with the command itself.

   Shorthand syntax
       When using the crm shell to manage clusters, you will end up typing a
       lot of commands many times over. Clear command names like configure
       help in understanding and learning to use the cluster shell, but is
       easy to misspell and is tedious to type repeatedly. The interactive
       mode and tab completion both help with this, but the crm shell also has
       the ability to understand a variety of shorthand aliases for all of the
       commands.

       For example, instead of typing crm status, you can type crm st or crm
       stat. Instead of crm configure you can type crm cfg or even crm cf. crm
       resource can be shorted as crm rsc, and so on.

       The exact list of accepted aliases is too long to print in full, but
       experimentation and typoes should help in discovering more of them.

FEATURES

       The feature set of crmsh covers a wide range of functionality, and
       understanding how and when to use the various features of the shell can
       be difficult. This section of the guide describes some of the features
       and use cases of crmsh in more depth. The intention is to provide a
       deeper understanding of these features, but also to serve as a guide to
       using them.

   Shadow CIB usage
       A Shadow CIB is a normal cluster configuration stored in a file. They
       may be manipulated in much the same way as the live CIB, with the key
       difference that changes to a shadow CIB have no effect on the actual
       cluster resources. An administrator may choose to apply any of them to
       the cluster, thus replacing the running configuration with the one
       found in the shadow CIB.

       The crm prompt always contains the name of the configuration which is
       currently in use, or the string live if using the live cluster
       configuration.

       When editing the configuration in the configure level, no changes are
       actually applied until the commit command is executed. It is possible
       to start editing a configuration as usual, but instead of committing
       the changes to the active CIB, save them to a shadow CIB.

       The following example configure session demonstrates how this can be
       done:

           crm(live)configure# cib new test-2
           INFO: test-2 shadow CIB created
           crm(test-2)configure# commit

   Configuration semantic checks
       Resource definitions may be checked against the meta-data provided with
       the resource agents. These checks are currently carried out:

       ·   are required parameters set

       ·   existence of defined parameters

       ·   timeout values for operations

       The parameter checks are obvious and need no further explanation.
       Failures in these checks are treated as configuration errors.

       The timeouts for operations should be at least as long as those
       recommended in the meta-data. Too short timeout values are a common
       mistake in cluster configurations and, even worse, they often slip
       through if cluster testing was not thorough. Though operation timeouts
       issues are treated as warnings, make sure that the timeouts are usable
       in your environment. Note also that the values given are just advisory
       minimum---your resources may require longer timeouts.

       User may tune the frequency of checks and the treatment of errors by
       the check-frequency and check-mode preferences.

       Note that if the check-frequency is set to always and the check-mode to
       strict, errors are not tolerated and such configuration cannot be
       saved.

   Configuration templates
       Deprecation note

       Configuration templates have been deprecated in favor of the more
       capable cluster scripts. To learn how to use cluster scripts, see the
       dedicated documentation on the crmsh website at
       http://crmsh.github.io/, or in the Script section.

       Configuration templates are ready made configurations created by
       cluster experts. They are designed in such a way so that users may
       generate valid cluster configurations with minimum effort. If you are
       new to Pacemaker, templates may be the best way to start.

       We will show here how to create a simple yet functional Apache
       configuration:

           # crm configure
           crm(live)configure# template
           crm(live)configure template# list templates
           apache       filesystem   virtual-ip
           crm(live)configure template# new web <TAB><TAB>
           apache       filesystem   virtual-ip
           crm(live)configure template# new web apache
           INFO: pulling in template apache
           INFO: pulling in template virtual-ip
           crm(live)configure template# list
           web2-d       web2     vip2     web3     vip      web

       We enter the template level from configure. Use the list command to
       show templates available on the system. The new command creates a
       configuration from the apache template. You can use tab completion to
       pick templates. Note that the apache template depends on a virtual IP
       address which is automatically pulled along. The list command shows the
       just created web configuration, among other configurations (I hope that
       you, unlike me, will use more sensible and descriptive names).

       The show command, which displays the resulting configuration, may be
       used to get an idea about the minimum required changes which have to be
       done. All ERROR messages show the line numbers in which the respective
       parameters are to be defined:

           crm(live)configure template# show
           ERROR: 23: required parameter ip not set
           ERROR: 61: required parameter id not set
           ERROR: 65: required parameter configfile not set
           crm(live)configure template# edit

       The edit command invokes the preferred text editor with the web
       configuration. At the top of the file, the user is advised how to make
       changes. A good template should require from the user to specify only
       parameters. For example, the web configuration we created above has the
       following required and optional parameters (all parameter lines start
       with %%):

           $ grep -n ^%% ~/.crmconf/web
           23:%% ip
           31:%% netmask
           35:%% lvs_support
           61:%% id
           65:%% configfile
           71:%% options
           76:%% envfiles

       These lines are the only ones that should be modified. Simply append
       the parameter value at the end of the line. For instance, after editing
       this template, the result could look like this (we used tabs instead of
       spaces to make the values stand out):

           $ grep -n ^%% ~/.crmconf/web
           23:%% ip        192.168.1.101
           31:%% netmask
           35:%% lvs_support
           61:%% id        websvc
           65:%% configfile    /etc/apache2/httpd.conf
           71:%% options
           76:%% envfiles

       As you can see, the parameter line format is very simple:

           %% <name> <value>

       After editing the file, use show again to display the configuration:

           crm(live)configure template# show
           primitive virtual-ip IPaddr \
               params ip=192.168.1.101
           primitive apache apache \
               params configfile="/etc/apache2/httpd.conf"
           monitor apache 120s:60s
           group websvc \
               apache virtual-ip

       The target resource of the apache template is a group which we named
       websvc in this sample session.

       This configuration looks exactly as you could type it at the configure
       level. The point of templates is to save you some typing. It is
       important, however, to understand the configuration produced.

       Finally, the configuration may be applied to the current crm
       configuration (note how the configuration changed slightly, though it
       is still equivalent, after being digested at the configure level):

           crm(live)configure template# apply
           crm(live)configure template# cd ..
           crm(live)configure# show
           node xen-b
           node xen-c
           primitive apache apache \
               params configfile="/etc/apache2/httpd.conf" \
               op monitor interval=120s timeout=60s
           primitive virtual-ip IPaddr \
               params ip=192.168.1.101
           group websvc apache virtual-ip

       Note that this still does not commit the configuration to the CIB which
       is used in the shell, either the running one (live) or some shadow CIB.
       For that you still need to execute the commit command.

       To complete our example, we should also define the preferred node to
       run the service:

           crm(live)configure# location websvc-pref websvc 100: xen-b

       If you are not happy with some resource names which are provided by
       default, you can rename them now:

           crm(live)configure# rename virtual-ip intranet-ip
           crm(live)configure# show
           node xen-b
           node xen-c
           primitive apache apache \
               params configfile="/etc/apache2/httpd.conf" \
               op monitor interval=120s timeout=60s
           primitive intranet-ip IPaddr \
               params ip=192.168.1.101
           group websvc apache intranet-ip
           location websvc-pref websvc 100: xen-b

       To summarize, working with templates typically consists of the
       following steps:

       ·   new: create a new configuration from templates

       ·   edit: define parameters, at least the required ones

       ·   show: see if the configuration is valid

       ·   apply: apply the configuration to the configure level

   Resource testing
       The amount of detail in a cluster makes all configurations prone to
       errors. By far the largest number of issues in a cluster is due to bad
       resource configuration. The shell can help quickly diagnose such
       problems. And considerably reduce your keyboard wear.

       Let’s say that we entered the following configuration:

           node xen-b
           node xen-c
           node xen-d
           primitive fencer stonith:external/libvirt \
               params hypervisor_uri="qemu+tcp://10.2.13.1/system" \
                   hostlist="xen-b xen-c xen-d" \
               op monitor interval=2h
           primitive svc Xinetd \
               params service=systat \
               op monitor interval=30s
           primitive intranet-ip IPaddr2 \
               params ip=10.2.13.100 \
               op monitor interval=30s
           primitive apache apache \
               params configfile="/etc/apache2/httpd.conf" \
               op monitor interval=120s timeout=60s
           group websvc apache intranet-ip
           location websvc-pref websvc 100: xen-b

       Before typing commit to submit the configuration to the cib we can make
       sure that all resources are usable on all nodes:

           crm(live)configure# rsctest websvc svc fencer

       It is important that resources being tested are not running on any
       nodes. Otherwise, the rsctest command will refuse to do anything. Of
       course, if the current configuration resides in a CIB shadow, then a
       commit is irrelevant. The point being that resources are not running on
       any node.  Note on stopping all resources

       Alternatively to not committing a configuration, it is also possible to
       tell Pacemaker not to start any resources:

           crm(live)configure# property stop-all-resources=yes

       Almost none---resources of class stonith are still started. But shell
       is not as strict when it comes to stonith resources.

       Order of resources is significant insofar that a resource depends on
       all resources to its left. In most configurations, it’s probably
       practical to test resources in several runs, based on their
       dependencies.

       Apart from groups, crm does not interpret constraints and therefore
       knows nothing about resource dependencies. It also doesn’t know if a
       resource can run on a node at all in case of an asymmetric cluster. It
       is up to the user to specify a list of eligible nodes if a resource is
       not meant to run on every node.

   Access Control Lists (ACL)
       Note on ACLs in Pacemaker 1.1.12

       The support for ACLs has been revised in Pacemaker version 1.1.12 and
       up. Depending on which version you are using, the information in this
       section may no longer be accurate. Look for the acl_target
       configuration element for more details on the new syntax.

       By default, the users from the haclient group have full access to the
       cluster (or, more precisely, to the CIB). Access control lists allow
       for finer access control to the cluster.

       Access control lists consist of an ordered set of access rules. Each
       rule allows read or write access or denies access completely. Rules are
       typically combined to produce a specific role. Then, users may be
       assigned a role.

       For instance, this is a role which defines a set of rules allowing
       management of a single resource:

           role bigdb_admin \
               write meta:bigdb:target-role \
               write meta:bigdb:is-managed \
               write location:bigdb \
               read ref:bigdb

       The first two rules allow modifying the target-role and is-managed meta
       attributes which effectively enables users in this role to stop/start
       and manage/unmanage the resource. The constraints write access rule
       allows moving the resource around. Finally, the user is granted read
       access to the resource definition.

       For proper operation of all Pacemaker programs, it is advisable to add
       the following role to all users:

           role read_all \
               read cib

       For finer grained read access try with the rules listed in the
       following role:

           role basic_read \
               read node attribute:uname \
               read node attribute:type \
               read property \
               read status

       It is however possible that some Pacemaker programs (e.g. ptest) may
       not function correctly if the whole CIB is not readable.

       Some of the ACL rules in the examples above are expanded by the shell
       to XPath specifications. For instance, meta:bigdb:target-role expands
       to:

           //primitive[@id='bigdb']/meta_attributes/nvpair[@name='target-role']

       You can see the expansion by showing XML:

           crm(live) configure# show xml bigdb_admin
           ...
           <acls>
             <acl_role id="bigdb_admin">
                 <write id="bigdb_admin-write"
                 xpath="//primitive[@id='bigdb']/meta_attributes/nvpair[@name='target-role']"/>

       Many different XPath expressions can have equal meaning. For instance,
       the following two are equal, but only the first one is going to be
       recognized as shortcut:

           //primitive[@id='bigdb']/meta_attributes/nvpair[@name='target-role']
           //resources/primitive[@id='bigdb']/meta_attributes/nvpair[@name='target-role']

       XPath is a powerful language, but you should try to keep your ACL
       xpaths simple and the builtin shortcuts should be used whenever
       possible.

   Syntax: Resource sets
       Using resource sets can be a bit confusing unless one knows the details
       of the implementation in Pacemaker as well as how to interpret the
       syntax provided by crmsh.

       Three different types of resource sets are provided by crmsh, and each
       one implies different values for the two resource set attributes,
       sequential and require-all.

       sequential
           If true, the resources in the set do not depend on each other
           internally. Setting sequential to true implies a strict order of
           dependency within the set.

       require-all
           If false, only one resource in the set is required to fulfil the
           requirements of the set. The set of A, B and C with require-all set
           to false is be read as "A OR B OR C" when its dependencies are
           resolved.

       The three types of resource sets modify the attributes in the following
       way:

        1. Implicit sets (no brackets).  sequential=true, require-all=true

        2. Parenthesis set (( ...  )).  sequential=false, require-all=true

        3. Bracket set ([ ...  ]).  sequential=false, require-all=false

       To create a set with the properties sequential=true and
       require-all=false, explicitly set sequential in a bracketed set, [ A B
       C sequential=true ].

       To create multiple sets with both sequential and require-all set to
       true, explicitly set sequential in a parenthesis set: A B ( C D
       sequential=true ).

   Syntax: Attribute list references
       Attribute lists are used to set attributes and parameters for
       resources, constraints and property definitions. For example, to set
       the virtual IP used by an IPAddr2 resource the attribute ip can be set
       in an attribute list for that resource.

       Attribute lists can have identifiers that name them, and other
       resources can reuse the same attribute list by referring to that name
       using an $id-ref. For example, the following statement defines a simple
       dummy resource with an attribute list which sets the parameter state to
       the value 1 and sets the identifier for the attribute list to on-state:

           primitive dummy-1 Dummy params $id=on-state state=1

       To refer to this attribute list from a different resource, refer to the
       on-state name using an id-ref:

           primitive dummy-2 Dummy params $id-ref=on-state

       The resource dummy-2 will now also have the parameter state set to the
       value 1.

   Syntax: Attribute references
       In some cases, referencing complete attribute lists is too
       coarse-grained, for example if two different parameters with different
       names should have the same value set. Instead of having to copy the
       value in multiple places, it is possible to create references to
       individual attributes in attribute lists.

       To name an attribute in order to be able to refer to it later, prefix
       the attribute name with a $ character (as seen above with the special
       names $id and $id-ref:

           primitive dummy-1 Dummy params $state=1

       The identifier state can now be used to refer to this attribute from
       other primitives, using the @<id> syntax:

           primitive dummy-2 Dummy params @state

       In some cases, using the attribute name as the identifier doesn’t work
       due to name clashes. In this case, the syntax $<id>:<name>=<value> can
       be used to give the attribute a different identifier:

           primitive dummy-1 params $dummy-state-on:state=1
           primitive dummy-2 params @dummy-state-on

       There is also the possibility that two resources both use the same
       attribute value but with different names. For example, a web server may
       have a parameter server_ip for setting the IP address where it listens
       for incoming requests, and a virtual IP resource may have a parameter
       called ip which sets the IP address it creates. To configure these two
       resources with an IP without repeating the value, the reference can be
       given a name using the syntax @<id>:<name>.

       Example:

           primitive virtual-ip IPaddr2 params $vip:ip=192.168.1.100
           primitive webserver apache params @vip:server_ip

   Syntax: Rule expressions
       Many of the configuration commands in crmsh now support the use of rule
       expressions, which can influence what attributes apply to a resource or
       under which conditions a constraint is applied, depending on changing
       conditions like date, time, the value of attributes and more.

       Here is an example of a simple rule expression used to apply a a
       different resource parameter on the node named node1:

           primitive my_resource Special \
             params 2: rule #uname eq node1 interface=eth1 \
             params 1: interface=eth0

       This primitive resource has two lists of parameters with descending
       priority. The parameter list with the highest priority is applied
       first, but only if the rule expressions for that parameter list all
       apply. In this case, the rule #uname eq node1 limits the parameter list
       so that it is only applied on `node1.

       Note that rule expressions are not terminated and are immediately
       followed by the data to which the rule is applied. In this case, the
       name-value pair interface=eth1.

       Rule expressions can contain multiple expressions connected using the
       boolean operator or and and. The full syntax for rule expressions is
       listed below.

           rules ::
             rule [id_spec] [$role=<role>] <score>: <expression>
             [rule [id_spec] [$role=<role>] <score>: <expression> ...]

           id_spec :: $id=<id> | $id-ref=<id>
           score :: <number> | <attribute> | [-]inf
           expression :: <simple_exp> [<bool_op> <simple_exp> ...]
           bool_op :: or | and
           simple_exp :: <attribute> [type:]<binary_op> <value>
                     | <unary_op> <attribute>
                     | date <date_expr>
           type :: <string> | <version> | <number>
           binary_op :: lt | gt | lte | gte | eq | ne
           unary_op :: defined | not_defined

           date_expr :: lt <end>
                    | gt <start>
                    | in start=<start> end=<end>
                    | in start=<start> <duration>
                    | spec <date_spec>
           duration|date_spec ::
                    hours=<value>
                    | monthdays=<value>
                    | weekdays=<value>
                    | yearsdays=<value>
                    | months=<value>
                    | weeks=<value>
                    | years=<value>
                    | weekyears=<value>
                    | moon=<value>

COMMAND REFERENCE

       The commands are structured to be compatible with the shell command
       line. Sometimes, the underlying Pacemaker grammar uses characters that
       have special meaning in bash, that will need to be quoted. This
       includes the hash or pound sign (#), single and double quotes, and any
       significant whitespace.

       Whitespace is also significant when assigning values, meaning that
       key=value is different from key = value.

       Commands can be referenced using short-hand as long as the short-hand
       is unique. This can be either a prefix of the command name or a prefix
       string of characters found in the name.

       For example, status can be abbreviated as st or su, and configure as
       conf or cfg.

       The syntax for the commands is given below in an informal, BNF-like
       grammar.

       ·   <value> denotes a string.

       ·   [value] means that the construct is optional.

       ·   The ellipsis (...) signifies that the previous construct may be
           repeated.

       ·   first|second means either first or second.

       ·   The rest are literals (strings, :, =).

   status
       Show cluster status. The status is displayed by crm_mon. Supply
       additional arguments for more information or different format. See
       crm_mon(8) for more details.

       Example:

           status
           status simple
           status full

       Usage:

           status [<option> ...]

           option :: full
                   | bynode
                   | inactive
                   | ops
                   | timing
                   | failcounts
                   | verbose
                   | quiet
                   | html
                   | xml
                   | simple
                   | tickets
                   | noheaders
                   | detail
                   | brief

   cluster - Cluster setup and management
       Whole-cluster configuration management with High Availability
       awareness.

       The commands on the cluster level allows configuration and modification
       of the underlying cluster infrastructure, and also supplies tools to do
       whole-cluster systems management.

       These commands enable easy installation and maintenance of a HA
       cluster, by providing support for package installation, configuration
       of the cluster messaging layer, file system setup and more.

       add
           This command simplifies the process of adding a new node to a
           running cluster. The new node will be installed and configured with
           the packages and configuration files needed to run the cluster
           resources. If a cluster file system is used, the new node will be
           set up to host the file system.

           This command should be executed from a node already in the cluster.

           Usage:

               add <node>

       health
           Runs a larger set of tests and queries on all nodes in the cluster
           to verify the general system health and detect potential problems.

           Usage:

               health

       init
           Installs and configures a basic HA cluster on a set of nodes.

           Usage:

               init node1 node2 node3
               init --dry-run node1 node2 node3

       remove
           This command simplifies the process of removing a node from the
           cluster, moving any resources hosted by that node to other nodes.

           Usage:

               remove <node>

       run
           This command takes a shell statement as argument, executes that
           statement on all nodes in the cluster, and reports the result.

           Usage:

               run <command>

           Example:

               run "cat /proc/uptime"

       copy
           Copy file to other cluster nodes.

           Copies the given file to all other nodes unless given a list of
           nodes to copy to as argument.

           Usage:

               copy <filename> [nodes ...]

           Example:

               copy /etc/motd

       start
           Starts the cluster-related system services on this node.

           Usage:

               start

       status
           Reports the status for the cluster messaging layer on the local
           node.

           Usage:

               status

       stop
           Stops the cluster-related system services on this node.

           Usage:

               stop

       wait_for_startup
           Mostly useful in scripts or automated workflows, this command will
           attempt to connect to the local cluster node repeatedly. The
           command will keep trying until the cluster node responds, or the
           timeout elapses. The timeout can be changed by supplying a value in
           seconds as an argument.

           Usage:

               wait_for_startup

       diff
           Displays the difference, if any, between a given file on different
           nodes. If the second argument is --checksum, a checksum of the file
           will be calculated and displayed for each node.

           Usage:

               diff <file> [--checksum] [nodes...]

           Example:

               diff /etc/crm/crm.conf node2
               diff /etc/resolv.conf --checksum

   script - Cluster script management
       A big part of the configuration and management of a cluster is
       collecting information about all cluster nodes and deploying changes to
       those nodes. Often, just performing the same procedure on all nodes
       will encounter problems, due to subtle differences in the
       configuration.

       For example, when configuring a cluster for the first time, the
       software needs to be installed and configured on all nodes before the
       cluster software can be launched and configured using crmsh. This
       process is cumbersome and error-prone, and the goal is for scripts to
       make this process easier.

       Scripts are implemented using the python parallax package which
       provides a thin wrapper on top of SSH. This allows the scripts to
       function through the usual SSH channels used for system maintenance,
       requiring no additional software to be installed or maintained.

       list
           Lists the available scripts, sorted by category. Scripts that have
           the special Script category are hidden by default, since they are
           mainly used by other scripts or commands. To also show these, pass
           all as argument.

           To get a flat list of script names, not sorted by category, pass
           names as an extra argument.

           Usage:

               list [all] [names]

           Example:

               list
               list all names

       show
           Prints a description and short summary of the script, with
           descriptions of the accepted parameters.

           Advanced parameters are hidden by default. To show the complete
           list of parameters accepted by the script, pass all as argument.

           Usage:

               show <script> [all]

           Example:

               show virtual-ip

       verify
           Checks the given parameter values, and returns a list of actions
           that will be executed when running the script if provided the same
           list of parameter values.

           Usage:

               verify <script> [args...]

           Example:

               verify sbd id=sbd-1 node=node1 sbd_device=/dev/disk/by-uuid/F00D-CAFE

       run
           Given a list of parameter values, this command will execute the
           actions specified by the cluster script. The format for the
           parameter values is the same as for the verify command.

           Can optionally take at least two parameters: * nodes=<nodes>: List
           of nodes that the script runs over * dry_run=yes|no: If set, the
           script will not perform any modifications.

           Additional parameters may be available depending on the script.

           Use the show command to see what parameters are available.

           Usage:

               run <script> [args...]

           Example:

               run apache install=true
               run sbd id=sbd-1 node=node1 sbd_device=/dev/disk/by-uuid/F00D-CAFE

       json
           This command provides a JSON API for the cluster scripts, intended
           for use in user interface tools that want to interact with the
           cluster via scripts.

           The command takes a single argument, which should be a JSON array
           with the first member identifying the command to perform.

           The output is line-based: Commands that return multiple results
           will return them line-by-line, ending with a terminator value:
           "end".

           When providing parameter values to this command, they should be
           provided as nested objects, so virtual-ip:ip=192.168.0.5 on the
           command line becomes the JSON object
           {"virtual-ip":{"ip":"192.168.0.5"}}.

           API:

               ["list"]
               => [{name, shortdesc, category}]

               ["show", <name>]
               => [{name, shortdesc, longdesc, category, <<steps>>}]

               <<steps>> := [{name, shortdesc], longdesc, required, parameters, steps}]

               <<params>> := [{name, shortdesc, longdesc, required, unique, advanced,
                               type, value, example}]

               ["verify", <name>, <<values>>]
               => [{shortdesc, longdesc, text, nodes}]

               ["run", <name>, <<values>>]
               => [{shortdesc, rc, output|error}]

   corosync - Corosync management
       Corosync is the underlying messaging layer for most HA clusters. This
       level provides commands for editing and managing the corosync
       configuration.

       add-node
           Adds a node to the corosync configuration. This is used with the
           udpu type configuration in corosync.

           A nodeid for the added node is generated automatically.

           Note that this command assumes that only a single ring is used, and
           sets only the address for ring0.

           Usage:

               add-node <addr>

       del-node
           Removes a node from the corosync configuration. The argument given
           is the ring0_addr address set in the configuration file.

           Usage:

               del-node <addr>

       diff
           Diffs the corosync configurations on different nodes. If no nodes
           are given as arguments, the corosync configurations on all nodes in
           the cluster are compared.

           diff takes an option argument --checksum, to display a checksum for
           each file instead of calculating a diff.

           Usage:

               diff [--checksum] [node...]

       edit
           Opens the Corosync configuration file in an editor.

           Usage:

               edit

       get
           Returns the value configured in corosync.conf, which is not
           necessarily the value used in the running configuration. See reload
           for telling corosync about configuration changes.

           The argument is the complete dot-separated path to the value.

           If there are multiple values configured with the same path, the
           command returns all values for that path. For example, to get all
           configured ring0_addr values, use this command:

           Example:

               get nodelist.node.ring0_addr

       log
           Opens the log file specified in the corosync configuration file. If
           no log file is configured, this command returns an error.

           The pager used can be configured either using the PAGER environment
           variable or in crm.conf.

           Usage:

               log

       pull
           Gets the corosync configuration from another node and copies it to
           this node.

           Usage:

               pull <node>

       push
           Pushes the corosync configuration file on this node to the list of
           nodes provided. If no target nodes are given, the configuration is
           pushed to all other nodes in the cluster.

           It is recommended to use csync2 to distribute the cluster
           configuration files rather than relying on this command.

           Usage:

               push [node] ...

           Example:

               push node-2 node-3

       reload
           Tells all instances of corosync in this cluster to reload
           corosync.conf.

           After pushing a new configuration to all cluster nodes, call this
           command to make corosync use the new configuration.

           Usage:

               reload

       set
           Sets the value identified by the given path. If the value does not
           exist in the configuration file, it will be added. However, if the
           section containing the value does not exist, the command will fail.

           Usage:

               set quorum.expected_votes 2

       show
           Displays the corosync configuration on the current node.

               show

       status
           Displays the status of Corosync, including the votequorum state.

           Usage:

               status

   cib - CIB shadow management
       This level is for management of shadow CIBs. It is available both at
       the top level and the configure level.

       All the commands are implemented using cib_shadow(8) and the CIB_shadow
       environment variable. The user prompt always includes the name of the
       currently active shadow or the live CIB.

       cibstatus
           Enter edit and manage the CIB status section level. See the CIB
           status management section.

       commit
           Apply a shadow CIB to the cluster. If the shadow name is omitted
           then the current shadow CIB is applied.

           Temporary shadow CIBs are removed automatically on commit.

           Usage:

               commit [<cib>]

       delete
           Delete an existing shadow CIB.

           Usage:

               delete <cib>

       diff
           Print differences between the current cluster configuration and the
           active shadow CIB.

           Usage:

               diff

       import
           At times it may be useful to create a shadow file from the existing
           CIB. The CIB may be specified as file or as a PE input file number.
           The shell will look up files in the local directory first and then
           in the PE directory (typically /var/lib/pengine). Once the CIB file
           is found, it is copied to a shadow and this shadow is immediately
           available for use at both configure and cibstatus levels.

           If the shadow name is omitted then the target shadow is named after
           the input CIB file.

           Note that there are often more than one PE input file, so you may
           need to specify the full name.

           Usage:

               import {<file>|<number>} [<shadow>]

           Examples:

               import pe-warn-2222
               import 2289 issue2

       list
           List existing shadow CIBs.

           Usage:

               list

       new
           Create a new shadow CIB. The live cluster configuration and status
           is copied to the shadow CIB.

           If the name of the shadow is omitted, we create a temporary CIB
           shadow. It is useful if multiple level sessions are desired without
           affecting the cluster. A temporary CIB shadow is short lived and
           will be removed either on commit or on program exit. Note that if
           the temporary shadow is not committed all changes in the temporary
           shadow are lost.

           Specify withstatus if you want to edit the status section of the
           shadow CIB (see the cibstatus section). Add force to force
           overwriting the existing shadow CIB.

           To start with an empty configuration that is not copied from the
           live CIB, specify the empty keyword. (This also allows a shadow CIB
           to be created in case no cluster is running.)

           Usage:

               new [<cib>] [withstatus] [force] [empty]

       reset
           Copy the current cluster configuration into the shadow CIB.

           Usage:

               reset <cib>

       use
           Choose a CIB source. If you want to edit the status from the shadow
           CIB specify withstatus (see cibstatus). Leave out the CIB name to
           switch to the running CIB.

           Usage:

               use [<cib>] [withstatus]

   ra - Resource Agents (RA) lists and documentation
       This level contains commands which show various information about the
       installed resource agents. It is available both at the top level and at
       the configure level.

       classes
           Print all resource agents' classes and, where appropriate, a list
           of available providers.

           Usage:

               classes

       info (meta)
           Show the meta-data of a resource agent type. This is where users
           can find information on how to use a resource agent. It is also
           possible to get information from some programs: pengine, crmd, cib,
           and stonithd. Just specify the program name instead of an RA.

           Usage:

               info [<class>:[<provider>:]]<type>
               info <type> <class> [<provider>] (obsolete)

           Example:

               info apache
               info ocf:pacemaker:Dummy
               info stonith:ipmilan
               info pengine

       list
           List available resource agents for the given class. If the class is
           ocf, supply a provider to get agents which are available only from
           that provider.

           Usage:

               list <class> [<provider>]

           Example:

               list ocf pacemaker

       providers
           List providers for a resource agent type. The class parameter
           defaults to ocf.

           Usage:

               providers <type> [<class>]

           Example:

               providers apache

       validate
           If the resource agent supports the validate-all action, this calls
           the action with the given parameters, printing any warnings or
           errors reported by the agent.

           Usage:

               validate <agent> [<key>=<value> ...]

   resource - Resource management
       At this level resources may be managed.

       All (or almost all) commands are implemented with the CRM tools such as
       crm_resource(8).

       cleanup
           Cleanup resource status. Typically done after the resource has
           temporarily failed. If a node is omitted, cleanup on all nodes. If
           there are many nodes, the command may take a while.

           Usage:

               cleanup <rsc> [<node>]

       demote
           Demote a master-slave resource using the target-role attribute.

           Usage:

               demote <rsc>

       failcount
           Show/edit/delete the failcount of a resource.

           Usage:

               failcount <rsc> set <node> <value>
               failcount <rsc> delete <node>
               failcount <rsc> show <node>

           Example:

               failcount fs_0 delete node2

       maintenance
           Enables or disables the per-resource maintenance mode. When this
           mode is enabled, no monitor operations will be triggered for the
           resource.

           Usage:

               maintenance <resource> [on|off|true|false]

           Example:

               maintenance rsc1
               maintenance rsc2 off

       manage
           Manage a resource using the is-managed attribute. If there are
           multiple meta attributes sets, the attribute is set in all of them.
           If the resource is a clone, all is-managed attributes are removed
           from the children resources.

           For details on group management see options manage-children.

           Usage:

               manage <rsc>

       meta
           Show/edit/delete a meta attribute of a resource. Currently, all
           meta attributes of a resource may be managed with other commands
           such as resource stop.

           Usage:

               meta <rsc> set <attr> <value>
               meta <rsc> delete <attr>
               meta <rsc> show <attr>

           Example:

               meta ip_0 set target-role stopped

       migrate (move)
           Migrate a resource to a different node. If node is left out, the
           resource is migrated by creating a constraint which prevents it
           from running on the current node. Additionally, you may specify a
           lifetime for the constraint---once it expires, the location
           constraint will no longer be active.

           Usage:

               migrate <rsc> [<node>] [<lifetime>] [force]

       ban
           Ban a resource from running on a certain node. If no node is given
           as argument, the resource is banned from the current location.

           See migrate for details on other arguments.

           Usage:

               ban <rsc> [<node>] [<lifetime>] [force]

       param
           Show/edit/delete a parameter of a resource.

           Usage:

               param <rsc> set <param> <value>
               param <rsc> delete <param>
               param <rsc> show <param>

           Example:

               param ip_0 show ip

       promote
           Promote a master-slave resource using the target-role attribute.

           Usage:

               promote <rsc>

       refresh
           Refresh CIB from the LRM status.  Note

           refresh has been deprecated and is now an alias for cleanup.

           Usage:

               refresh [<node>]

       reprobe
           Probe for resources not started by the CRM.  Note

           reprobe has been deprecated and is now an alias for cleanup.

           Usage:

               reprobe [<node>]

       restart
           Restart one or more resources. This is essentially a shortcut for
           resource stop followed by a start. The shell is first going to wait
           for the stop to finish, that is for all resources to really stop,
           and only then to order the start action. Due to this command
           entailing a whole set of operations, informational messages are
           printed to let the user see some progress.

           For details on group management see options manage-children.

           Usage:

               restart <rsc> [<rsc> ...]

           Example:

               # crm resource restart g_webserver
               INFO: ordering g_webserver to stop
               waiting for stop to finish .... done
               INFO: ordering g_webserver to start
               #

       constraints
           Display the location and colocation constraints affecting the
           resource.

           Usage:

               constraints <rsc>

       operations
           Show active operations, optionally filtered by resource and node.

           Usage:

               operations [<rsc>] [<node>]

       scores
           Display the allocation scores for all resources.

           Usage:

               scores

       secret
           Sensitive parameters can be kept in local files rather than CIB in
           order to prevent accidental data exposure. Use the secret command
           to manage such parameters. stash and unstash move the value from
           the CIB and back to the CIB respectively. The set subcommand sets
           the parameter to the provided value. delete removes the parameter
           completely. show displays the value of the parameter from the local
           file. Use check to verify if the local file content is valid.

           Usage:

               secret <rsc> set <param> <value>
               secret <rsc> stash <param>
               secret <rsc> unstash <param>
               secret <rsc> delete <param>
               secret <rsc> show <param>
               secret <rsc> check <param>

           Example:

               secret fence_1 show password
               secret fence_1 stash password
               secret fence_1 set password secret_value

       start
           Start one or more resources by setting the target-role attribute.
           If there are multiple meta attributes sets, the attribute is set in
           all of them. If the resource is a clone, all target-role attributes
           are removed from the children resources.

           For details on group management see options manage-children.

           Usage:

               start <rsc> [<rsc> ...]

       status (show, list)
           Print resource status. More than one resource can be shown at once.
           If the resource parameter is left out, the status of all resources
           is printed.

           Usage:

               status [<rsc> ...]

       stop
           Stop one or more resources using the target-role attribute. If
           there are multiple meta attributes sets, the attribute is set in
           all of them. If the resource is a clone, all target-role attributes
           are removed from the children resources.

           For details on group management see options manage-children.

           Usage:

               stop <rsc> [<rsc> ...]

       trace
           Start tracing RA for the given operation. The trace files are
           stored in $HA_VARLIB/trace_ra. If the operation to be traced is
           monitor, note that the number of trace files can grow very quickly.

           If no operation name is given, crmsh will attempt to trace all
           operations for the RA. This includes any configured operations,
           start and stop as well as promote/demote for multistate resources.

           To trace the probe operation which exists for all resources, either
           set a trace for monitor with interval 0, or use probe as the
           operation name.

           Usage:

               trace <rsc> [<op> [<interval>] ]

           Example:

               trace fs start
               trace webserver
               trace webserver probe
               trace fs monitor 0

       unmanage
           Unmanage a resource using the is-managed attribute. If there are
           multiple meta attributes sets, the attribute is set in all of them.
           If the resource is a clone, all is-managed attributes are removed
           from the children resources.

           For details on group management see options manage-children.

           Usage:

               unmanage <rsc>

       unmigrate (unmove)
           Remove the constraint generated by the previous migrate command.

           Usage:

               unmigrate <rsc>

       untrace
           Stop tracing RA for the given operation. If no operation name is
           given, crmsh will attempt to stop tracing all operations in
           resource.

           Usage:

               untrace <rsc> [<op> [<interval>] ]

           Example:

               untrace fs start
               untrace webserver

       utilization
           Show/edit/delete a utilization attribute of a resource. These
           attributes describe hardware requirements. By setting the
           placement-strategy cluster property appropriately, it is possible
           then to distribute resources based on resource requirements and
           node size. See also node utilization attributes.

           Usage:

               utilization <rsc> set <attr> <value>
               utilization <rsc> delete <attr>
               utilization <rsc> show <attr>

           Example:

               utilization xen1 set memory 4096

   node - Node management
       Node management and status commands.

       attribute
           Edit node attributes. This kind of attribute should refer to
           relatively static properties, such as memory size.

           Usage:

               attribute <node> set <attr> <value>
               attribute <node> delete <attr>
               attribute <node> show <attr>

           Example:

               attribute node_1 set memory_size 4096

       clearstate
           Resets and clears the state of the specified node. This node is
           afterwards assumed clean and offline. This command can be used to
           manually confirm that a node has been fenced (e.g., powered off).

           Be careful! This can cause data corruption if you confirm that a
           node is down that is, in fact, not cleanly down - the cluster will
           proceed as if the fence had succeeded, possibly starting resources
           multiple times.

           Usage:

               clearstate <node>

       delete
           Delete a node. This command will remove the node from the CIB and,
           in case the cluster stack is running, use the appropriate program
           (crm_node or hb_delnode) to remove the node from the membership.

           If the node is still listed as active and a member of our partition
           we refuse to remove it. With the global force option (-F) we will
           try to delete the node anyway.

           Usage:

               delete <node>

       fence
           Make CRM fence a node. This functionality depends on stonith
           resources capable of fencing the specified node. No such stonith
           resources, no fencing will happen.

           Usage:

               fence <node>

       maintenance
           Set the node status to maintenance. This is equivalent to the
           cluster-wide maintenance-mode property but puts just one node into
           the maintenance mode.

           The node parameter defaults to the node where the command is run.

           Usage:

               maintenance [<node>]

       online
           Set a node to online status.

           The node parameter defaults to the node where the command is run.

           Usage:

               online [<node>]

       ready
           Set the node’s maintenance status to off. The node should be now
           again fully operational and capable of running resource operations.

           The node parameter defaults to the node where the command is run.

           Usage:

               ready [<node>]

       show
           Show a node definition. If the node parameter is omitted then all
           nodes are shown.

           Usage:

               show [<node>]

       standby
           Set a node to standby status. The node parameter defaults to the
           node where the command is run.

           Additionally, you may specify a lifetime for the standby---if set
           to reboot, the node will be back online once it reboots. forever
           will keep the node in standby after reboot. The life time defaults
           to forever.

           Usage:

               standby [<node>] [<lifetime>]

               lifetime :: reboot | forever

           Example:

               standby bob reboot

       status
           Show nodes' status as XML. If the node parameter is omitted then
           all nodes are shown.

           Usage:

               status [<node>]

       status-attr
           Edit node attributes which are in the CIB status section, i.e.
           attributes which hold properties of a more volatile nature. One
           typical example is attribute generated by the pingd utility.

           Usage:

               status-attr <node> set <attr> <value>
               status-attr <node> delete <attr>
               status-attr <node> show <attr>

           Example:

               status-attr node_1 show pingd

       utilization
           Edit node utilization attributes. These attributes describe
           hardware characteristics as integer numbers such as memory size or
           the number of CPUs. By setting the placement-strategy cluster
           property appropriately, it is possible then to distribute resources
           based on resource requirements and node size. See also resource
           utilization attributes.

           Usage:

               utilization <node> set <attr> <value>
               utilization <node> delete <attr>
               utilization <node> show <attr>

           Examples:

               utilization node_1 set memory 16384
               utilization node_1 show cpu

   site - GEO clustering site support
       A cluster may consist of two or more subclusters in different and
       distant locations. This set of commands supports such setups.

       ticket
           Tickets are cluster-wide attributes. They can be managed at the
           site where this command is executed.

           It is then possible to constrain resources depending on the ticket
           availability (see the rsc_ticket command for more details).

           Usage:

               ticket {grant|revoke|standby|activate|show|time|delete} <ticket>

           Example:

               ticket grant ticket1

   options - User preferences
       The user may set various options for the crm shell itself.

       add-quotes
           The shell (as in /bin/sh) parser strips quotes from the command
           line. This may sometimes make it really difficult to type values
           which contain white space. One typical example is the configure
           filter command. The crm shell will supply extra quotes around
           arguments which contain white space. The default is yes.  Note on
           quotes use

           Adding quotes around arguments automatically has been introduced
           with version 1.2.2 and it is technically a regression. Being a
           regression is the only reason the add-quotes option exists. If you
           have custom shell scripts which would break, just set the
           add-quotes option to no.

           For instance, with adding quotes enabled, it is possible to do the
           following:

               # crm configure primitive d1 Dummy \
                   meta description="some description here"
               # crm configure filter 'sed "s/hostlist=./&node-c /"' fencing

       check-frequency
           Semantic check of the CIB or elements modified or created may be
           done on every configuration change (always), when verifying
           (on-verify) or never. It is by default set to always. Experts may
           want to change the setting to on-verify.

           The checks require that resource agents are present. If they are
           not installed at the configuration time set this preference to
           never.

           See Configuration semantic checks for more details.

       check-mode
           Semantic check of the CIB or elements modified or created may be
           done in the strict mode or in the relaxed mode. In the former
           certain problems are treated as configuration errors. In the
           relaxed mode all are treated as warnings. The default is strict.

           See Configuration semantic checks for more details.

       colorscheme
           With output set to color, a comma separated list of colors from
           this option are used to emphasize:

           ·   keywords

           ·   object ids

           ·   attribute names

           ·   attribute values

           ·   scores

           ·   resource references

           crm can show colors only if there is curses support for python
           installed (usually provided by the python-curses package). The
           colors are whatever is available in your terminal. Use normal if
           you want to keep the default foreground color.

           This user preference defaults to
           yellow,normal,cyan,red,green,magenta which is good for terminals
           with dark background. You may want to change the color scheme and
           save it in the preferences file for other color setups.

           Example:

               colorscheme yellow,normal,blue,red,green,magenta

       editor
           The edit command invokes an editor. Use this to specify your
           preferred editor program. If not set, it will default to either the
           value of the EDITOR environment variable or to one of the standard
           UNIX editors (vi,emacs,nano).

           Usage:

               editor program

           Example:

               editor vim

       manage-children
           Some resource management commands, such as resource stop, when the
           target resource is a group, may not always produce desired result.
           Each element, group and the primitive members, can have a meta
           attribute and those attributes may end up with conflicting values.
           Consider the following construct:

               crm(live)# configure show svc fs virtual-ip
               primitive fs Filesystem \
                   params device="/dev/drbd0" directory="/srv/nfs" fstype=ext3 \
                   op monitor interval=10s \
                   meta target-role=Started
               primitive virtual-ip IPaddr2 \
                   params ip=10.2.13.110 iflabel=1 \
                   op monitor interval=10s \
                   op start interval=0 \
                   meta target-role=Started
               group svc fs virtual-ip \
                   meta target-role=Stopped

           Even though the element svc should be stopped, the group is
           actually running because all its members have the target-role set
           to Started:

               crm(live)# resource show svc
               resource svc is running on: xen-f

           Hence, if the user invokes resource stop svc the intention is not
           clear. This preference gives the user an opportunity to better
           control what happens if attributes of group members have values
           which are in conflict with the same attribute of the group itself.

           Possible values are ask (the default), always, and never. If set to
           always, the crm shell removes all children attributes which have
           values different from the parent. If set to never, all children
           attributes are left intact. Finally, if set to ask, the user will
           be asked for each member what is to be done.

       output
           crm can adorn configurations in two ways: in color (similar to for
           instance the ls --color command) and by showing keywords in upper
           case. Possible values are plain, color-always, color, and
           uppercase. It is possible to combine uppercase with one of the
           color values in order to get an upper case xmass tree. Just set
           this option to color,uppercase or color-always,uppercase. In case
           you need color codes in pipes, color-always forces color codes even
           in case the terminal is not a tty (just like ls --color=always).

       pager
           The view command displays text through a pager. Use this to specify
           your preferred pager program. If not set, it will default to either
           the value of the PAGER environment variable or to one of the
           standard UNIX system pagers (less,more,pg).

       reset
           This command resets all user options to the defaults. If used as a
           single-shot command, the rc file ($HOME/.config/crm/rc) is reset to
           the defaults too.

       save
           Save current settings to the rc file ($HOME/.config/crm/rc). On
           further crm runs, the rc file is automatically read and parsed.

       set
           Sets the value of an option. Takes the fully qualified name of the
           option as argument, as displayed by show all.

           The modified option value is stored in the user-local configuration
           file, usually found in ~/.config/crm/crm.conf.

           Usage:

               set <option> <value>

           Example:

               set color.warn "magenta bold"
               set editor nano

       show
           Display all current settings.

           Given an option name as argument, show will display only the value
           of that argument.

           Given all as argument, show displays all available user options.

           Usage:

               show [all|<option>]

           Example:

               show
               show skill-level
               show all

       skill-level
           Based on the skill-level setting, the user is allowed to use only a
           subset of commands. There are three levels: operator,
           administrator, and expert. The operator level allows only commands
           at the resource and node levels, but not editing or deleting
           resources. The administrator may do that and may also configure the
           cluster at the configure level and manage the shadow CIBs. The
           expert may do all.

           Usage:

               skill-level <level>

               level :: operator | administrator | expert
           Note on security

           The skill-level option is advisory only. There is nothing stopping
           any users change their skill level (see Access Control Lists (ACL)
           on how to enforce access control).

       sort-elements
           crm by default sorts CIB elements. If you want them appear in the
           order they were created, set this option to no.

           Usage:

               sort-elements {yes|no}

           Example:

               sort-elements no

       user
           Sufficient privileges are necessary in order to manage a cluster:
           programs such as crm_verify or crm_resource and, ultimately,
           cibadmin have to be run either as root or as the CRM owner user
           (typically hacluster). You don’t have to worry about that if you
           run crm as root. A more secure way is to run the program with your
           usual privileges, set this option to the appropriate user (such as
           hacluster), and setup the sudoers file.

           Usage:

               user system-user

           Example:

               user hacluster

       wait
           In normal operation, crm runs a command and gets back immediately
           to process other commands or get input from the user. With this
           option set to yes it will wait for the started transition to
           finish. In interactive mode dots are printed to indicate progress.

           Usage:

               wait {yes|no}

           Example:

               wait yes

   configure - CIB configuration
       This level enables all CIB object definition commands.

       The configuration may be logically divided into four parts: nodes,
       resources, constraints, and (cluster) properties and attributes. Each
       of these commands support one or more basic CIB objects.

       Nodes and attributes describing nodes are managed using the node
       command.

       Commands for resources are:

       ·   primitive

       ·   monitor

       ·   group

       ·   clone

       ·   ms/master (master-slave)

       In order to streamline large configurations, it is possible to define a
       template which can later be referenced in primitives:

       ·   rsc_template

       In that case the primitive inherits all attributes defined in the
       template.

       There are three types of constraints:

       ·   location

       ·   colocation

       ·   order

       It is possible to define fencing order (stonith resource priorities):

       ·   fencing_topology

       Finally, there are the cluster properties, resource meta attributes
       defaults, and operations defaults. All are just a set of attributes.
       These attributes are managed by the following commands:

       ·   property

       ·   rsc_defaults

       ·   op_defaults

       In addition to the cluster configuration, the Access Control Lists
       (ACL) can be setup to allow access to parts of the CIB for users other
       than root and hacluster. The following commands manage ACL:

       ·   user

       ·   role

       In Pacemaker 1.1.12 and up, this command replaces the user command for
       handling ACLs:

       ·   acl_target

       The changes are applied to the current CIB only on ending the
       configuration session or using the commit command.

       Comments start with # in the first line. The comments are tied to the
       element which follows. If the element moves, its comments will follow.

       acl_target
           Defines an ACL target.

           Usage:

               acl_target <tid> [<role> ...]

           Example:

               acl_target joe resource_admin constraint_editor

       cib
           This level is for management of shadow CIBs. It is available at the
           configure level to enable saving intermediate changes to a shadow
           CIB instead of to the live cluster. This short excerpt shows how:

               crm(live)configure# cib new test-2
               INFO: test-2 shadow CIB created
               crm(test-2)configure# commit

           Note how the current CIB in the prompt changed from live to test-2
           after issuing the cib new command. See also the CIB shadow
           management for more information.

       cibstatus
           Enter edit and manage the CIB status section level. See the CIB
           status management section.

       clone
           The clone command creates a resource clone. It may contain a single
           primitive resource or one group of resources.

           Usage:

               clone <name> <rsc>
                 [description=<description>]
                 [meta <attr_list>]
                 [params <attr_list>]

               attr_list :: [$id=<id>] <attr>=<val> [<attr>=<val>...] | $id-ref=<id>

           Example:

               clone cl_fence apc_1 \
                 meta clone-node-max=1 globally-unique=false

       colocation (collocation)
           This constraint expresses the placement relation between two or
           more resources. If there are more than two resources, then the
           constraint is called a resource set.

           The score is used to indicate the priority of the constraint. A
           positive score indicates that the resources should run on the same
           node. A negative score that they should not run on the same node.
           Values of positive or negative infinity indicate a mandatory
           constraint.

           In the two resource form, the cluster will place <with-rsc> first,
           and then decide where to put the <rsc> resource.

           Collocation resource sets have an extra attribute (sequential) to
           allow for sets of resources which don’t depend on each other in
           terms of state. The shell syntax for such sets is to put resources
           in parentheses.

           Sets cannot be nested.

           The optional node-attribute can be used to colocate resources on a
           set of nodes and not necessarily on the same node. For example, by
           setting a node attribute color on all nodes and setting the
           node-attribute value to color as well, the colocated resources will
           be placed on any node that has the same color.

           For more details on how to configure resource sets, see Syntax:
           Resource sets.

           Usage:

               colocation <id> <score>: <rsc>[:<role>] <with-rsc>[:<role>]
                 [node-attribute=<node_attr>]

               colocation <id> <score>: <resource_sets>
                 [node-attribute=<node_attr>]

               resource_sets :: <resource_set> [<resource_set> ...]

               resource_set :: ["("|"["] <rsc>[:<role>] [<rsc>[:<role>] ...] \
                               [<attributes>]  [")"|"]"]

               attributes :: [require-all=(true|false)] [sequential=(true|false)]

           Example:

               colocation never_put_apache_with_dummy -inf: apache dummy
               colocation c1 inf: A ( B C )

       commit
           Commit the current configuration to the CIB in use. As noted
           elsewhere, commands in a configure session don’t have immediate
           effect on the CIB. All changes are applied at one point in time,
           either using commit or when the user leaves the configure level. In
           case the CIB in use changed in the meantime, presumably by somebody
           else, the crm shell will refuse to apply the changes.

           If you know that it’s fine to still apply them, add force to the
           command line.

           To disable CIB patching and apply the changes by replacing the CIB
           completely, add replace to the command line. Note that this can
           lead to previous changes being overwritten if some other process
           concurrently modifies the CIB.

           Usage:

               commit [force] [replace]

       default-timeouts
           This command takes the timeouts from the actions section of the
           resource agent meta-data and sets them for the operations of the
           primitive.

           Usage:

               default-timeouts <id> [<id>...]
           Note on default-timeouts

           The use of this command is discouraged in favor of manually
           determining the best timeouts required for the particular
           configuration. Relying on the resource agent to supply appropriate
           timeouts can cause the resource to fail at the worst possible
           moment.

           Appropriate timeouts for resource actions are context-sensitive,
           and should be carefully considered with the whole configuration in
           mind.

       delete
           Delete one or more objects. If an object to be deleted belongs to a
           container object, such as a group, and it is the only resource in
           that container, then the container is deleted as well. Any related
           constraints are removed as well.

           If the object is a started resource, it will not be deleted unless
           the --force flag is passed to the command, or the force option is
           set.

           Usage:

               delete [--force] <id> [<id>...]

       edit
           This command invokes the editor with the object description. As
           with the show command, the user may choose to edit all objects or a
           set of objects.

           If the user insists, he or she may edit the XML edition of the
           object. If you do that, don’t modify any id attributes.

           Usage:

               edit [xml] [<id> ...]
               edit [xml] changed
           Note on renaming element ids

           The edit command sometimes cannot properly handle modifying element
           ids. In particular for elements which belong to group or ms
           resources. Group and ms resources themselves also cannot be
           renamed. Please use the rename command instead.

       erase
           The erase clears all configuration. Apart from nodes. To remove
           nodes, you have to specify an additional keyword nodes.

           Note that removing nodes from the live cluster may have some
           strange/interesting/unwelcome effects.

           Usage:

               erase [nodes]

       fencing_topology
           If multiple fencing (stonith) devices are available capable of
           fencing a node, their order may be specified by fencing_topology.
           The order is specified per node.

           Stonith resources can be separated by , in which case all of them
           need to succeed. If they fail, the next stonith resource (or set of
           resources) is used. In other words, use comma to separate resources
           which all need to succeed and whitespace for serial order. It is
           not allowed to use whitespace around comma.

           If the node is left out, the order is used for all nodes. That
           should reduce the configuration size in some stonith setups.

           From Pacemaker version 1.1.14, it is possible to use a node
           attribute as the target in a fencing topology. The syntax for this
           usage is described below.

           Usage:

               fencing_topology <stonith_resources> [<stonith_resources> ...]
               fencing_topology <fencing_order> [<fencing_order> ...]

               fencing_order :: <target> <stonith_resources> [<stonith_resources> ...]

               stonith_resources :: <rsc>[,<rsc>...]
               target :: <node>: | attr:<node-attribute>=<value>

           Example:

               # Only kill the power if poison-pill fails
               fencing_topology poison-pill power

               # As above for node-a, but a different strategy for node-b
               fencing_topology \
                   node-a: poison-pill power \
                   node-b: ipmi serial

               # Fencing anything on rack 1 requires fencing via both APC 1 and 2,
               # to defeat the redundancy provided by two separate UPS units.
               fencing_topology attr:rack=1 apc01,apc02

       filter
           This command filters the given CIB elements through an external
           program. The program should accept input on stdin and send output
           to stdout (the standard UNIX filter conventions). As with the show
           command, the user may choose to filter all or just a subset of
           elements.

           It is possible to filter the XML representation of objects, but
           probably not as useful as the configuration language. The
           presentation is somewhat different from what would be displayed by
           the show command---each element is shown on a single line, i.e.
           there are no backslashes and no other embelishments.

           Don’t forget to put quotes around the filter if it contains spaces.

           Usage:

               filter <prog> [xml] [<id> ...]
               filter <prog> [xml] changed

           Examples:

               filter "sed '/^primitive/s/target-role=[^ ]*//'"
               # crm configure filter "sed '/^primitive/s/target-role=[^ ]*//'"
               crm configure <<END
                 filter "sed '/threshold=\"1\"/s/=\"1\"/=\"0\"/g'"
               END
           Note on quotation marks

           Filter commands which feature a blend of quotation marks can be
           difficult to get right, especially when used directly from bash,
           since bash does its own quotation parsing. In these cases, it can
           be easier to supply the filter command as standard input. See the
           last example above.

       graph
           Create a graphviz graphical layout from the current cluster
           configuration.

           Currently, only dot (directed graph) is supported. It is
           essentially a visualization of resource ordering.

           The graph may be saved to a file which can be used as source for
           various graphviz tools (by default it is displayed in the user’s
           X11 session). Optionally, by specifying the format, one can also
           produce an image instead.

           For more or different graphviz attributes, it is possible to save
           the default set of attributes to an ini file. If this file exists
           it will always override the builtin settings. The exportsettings
           subcommand also prints the location of the ini file.

           Usage:

               graph [<gtype> [<file> [<img_format>]]]
               graph exportsettings

               gtype :: dot
               img_format :: `dot` output format (see the +-T+ option)

           Example:

               graph dot
               graph dot clu1.conf.dot
               graph dot clu1.conf.svg svg

       group
           The group command creates a group of resources. This can be useful
           when resources depend on other resources and require that those
           resources start in order on the same node. A commmon use of
           resource groups is to ensure that a server and a virtual IP are
           located together, and that the virtual IP is started before the
           server.

           Grouped resources are started in the order they appear in the
           group, and stopped in the reverse order. If a resource in the group
           cannot run anywhere, resources following it in the group will not
           start.

           group can be passed the "container" meta attribute, to indicate
           that it is to be used to group VM resources monitored using Nagios.
           The resource referred to by the container attribute must be of type
           ocf:heartbeat:Xen, oxf:heartbeat:VirtualDomain or
           ocf:heartbeat:lxc.

           Usage:

               group <name> <rsc> [<rsc>...]
                 [description=<description>]
                 [meta attr_list]
                 [params attr_list]

               attr_list :: [$id=<id>] <attr>=<val> [<attr>=<val>...] | $id-ref=<id>

           Example:

               group internal_www disk0 fs0 internal_ip apache \
                 meta target_role=stopped

               group vm-and-services vm vm-sshd meta container="vm"

       load
           Load a part of configuration (or all of it) from a local file or a
           network URL. The replace method replaces the current configuration
           with the one from the source. The update tries to import the
           contents into the current configuration. The file may be a CLI file
           or an XML file.

           If the URL is -, the configuration is read from standard input.

           Usage:

               load [xml] <method> URL

               method :: replace | update

           Example:

               load xml update myfirstcib.xml
               load xml replace http://storage.big.com/cibs/bigcib.xml

       location
           location defines the preference of nodes for the given resource.
           The location constraints consist of one or more rules which specify
           a score to be awarded if the rule matches.

           The resource referenced by the location constraint can be one of
           the following:

           ·   Plain resource reference: location loc1 webserver 100: node1

           ·   Resource set in curly brackets: location loc1 { virtual-ip
               webserver } 100: node1

           ·   Tag containing resource ids: location loc1 tag1 100: node1

           ·   Resource pattern: location loc1 /web.*/ 100: node1

           The resource-discovery attribute allows probes to be selectively
           enabled or disabled per resource and node.

           The syntax for resource sets is described in detail for colocation.

           For more details on how to configure resource sets, see Syntax:
           Resource sets.

           For more information on rule expressions, see Syntax: Rule
           expressions.

           Usage:

               location <id> <rsc> [<attributes>] {<node_pref>|<rules>}

               rsc :: /<rsc-pattern>/
                       | { resource_sets }
                       | <rsc>

               attributes :: role=<role> | resource-discovery=always|never|exclusive

               node_pref :: <score>: <node>

               rules ::
                 rule [id_spec] [$role=<role>] <score>: <expression>
                 [rule [id_spec] [$role=<role>] <score>: <expression> ...]

               id_spec :: $id=<id> | $id-ref=<id>
               score :: <number> | <attribute> | [-]inf
               expression :: <simple_exp> [<bool_op> <simple_exp> ...]
               bool_op :: or | and
               simple_exp :: <attribute> [type:]<binary_op> <value>
                         | <unary_op> <attribute>
                         | date <date_expr>
               type :: string | version | number
               binary_op :: lt | gt | lte | gte | eq | ne
               unary_op :: defined | not_defined

               date_expr :: lt <end>
                        | gt <start>
                        | in start=<start> end=<end>
                        | in start=<start> <duration>
                        | spec <date_spec>
               duration|date_spec ::
                        hours=<value>
                        | monthdays=<value>
                        | weekdays=<value>
                        | yearsdays=<value>
                        | months=<value>
                        | weeks=<value>
                        | years=<value>
                        | weekyears=<value>
                        | moon=<value>

           Examples:

               location conn_1 internal_www 100: node1

               location conn_1 internal_www \
                 rule 50: #uname eq node1 \
                 rule pingd: defined pingd

               location conn_2 dummy_float \
                 rule -inf: not_defined pingd or pingd number:lte 0

               # never probe for rsc1 on node1
               location no-probe rsc1 resource-discovery=never -inf: node1

       modgroup
           Add or remove primitives in a group. The add subcommand appends the
           new group member by default. Should it go elsewhere, there are
           after and before clauses.

           Usage:

               modgroup <id> add <id> [after <id>|before <id>]
               modgroup <id> remove <id>

           Examples:

               modgroup share1 add storage2 before share1-fs

       monitor
           Monitor is by far the most common operation. It is possible to add
           it without editing the whole resource. Also, long primitive
           definitions may be a bit uncluttered. In order to make this command
           as concise as possible, less common operation attributes are not
           available. If you need them, then use the op part of the primitive
           command.

           Usage:

               monitor <rsc>[:<role>] <interval>[:<timeout>]

           Example:

               monitor apcfence 60m:60s

           Note that after executing the command, the monitor operation may be
           shown as part of the primitive definition.

       ms (master)
           The ms command creates a master/slave resource type. It may contain
           a single primitive resource or one group of resources.

           Usage:

               ms <name> <rsc>
                 [description=<description>]
                 [meta attr_list]
                 [params attr_list]

               attr_list :: [$id=<id>] <attr>=<val> [<attr>=<val>...] | $id-ref=<id>

           Example:

               ms disk1 drbd1 \
                 meta notify=true globally-unique=false
           Note on id-ref usage

           Instance or meta attributes (‘params` and meta) may contain a
           reference to another set of attributes. In that case, no other
           attributes are allowed. Since attribute sets’ ids, though they do
           exist, are not shown in the crm, it is also possible to reference
           an object instead of an attribute set. crm will automatically
           replace such a reference with the right id:

               crm(live)configure# primitive a2 www-2 meta $id-ref=a1
               crm(live)configure# show a2
               primitive a2 apache \
                   meta $id-ref=a1-meta_attributes
                   [...]

           It is advisable to give meaningful names to attribute sets which
           are going to be referenced.

       node
           The node command describes a cluster node. Nodes in the CIB are
           commonly created automatically by the CRM. Hence, you should not
           need to deal with nodes unless you also want to define node
           attributes. Note that it is also possible to manage node attributes
           at the node level.

           Usage:

               node [$id=<id>] <uname>[:<type>]
                 [description=<description>]
                 [attributes [$id=<id>] [<score>:] [rule...]
                   <param>=<value> [<param>=<value>...]] | $id-ref=<ref>
                 [utilization [$id=<id>] [<score>:] [rule...]
                   <param>=<value> [<param>=<value>...]] | $id-ref=<ref>

               type :: normal | member | ping | remote

           Example:

               node node1
               node big_node attributes memory=64

       op_defaults
           Set defaults for the operations meta attributes.

           For more information on rule expressions, see Syntax: Rule
           expressions.

           Usage:

               op_defaults [$id=<set_id>] [rule ...] <option>=<value> [<option>=<value> ...]

           Example:

               op_defaults record-pending=true

       order
           This constraint expresses the order of actions on two resources or
           more resources. If there are more than two resources, then the
           constraint is called a resource set.

           Ordered resource sets have an extra attribute to allow for sets of
           resources whose actions may run in parallel. The shell syntax for
           such sets is to put resources in parentheses.

           If the subsequent resource can start or promote after any one of
           the resources in a set has done, enclose the set in brackets ([ and
           ]).

           Sets cannot be nested.

           Three strings are reserved to specify a kind of order constraint:
           Mandatory, Optional, and Serialize. It is preferred to use one of
           these settings instead of score. Previous versions mapped scores 0
           and inf to keywords advisory and mandatory. That is still valid but
           deprecated.

           For more details on how to configure resource sets, see Syntax:
           Resource sets.

           Usage:

               order <id> [{kind|<score>}:] first then [symmetrical=<bool>]

               order <id> [{kind|<score>}:] resource_sets [symmetrical=<bool>]

               kind :: Mandatory | Optional | Serialize

               first :: <rsc>[:<action>]

               then ::  <rsc>[:<action>]

               resource_sets :: resource_set [resource_set ...]

               resource_set :: ["["|"("] <rsc>[:<action>] [<rsc>[:<action>] ...] \
                               [attributes] ["]"|")"]

               attributes :: [require-all=(true|false)] [sequential=(true|false)]

           Example:

               order o-1 Mandatory: apache:start ip_1
               order o-2 Serialize: A ( B C )
               order o-3 inf: [ A B ] C
               order o-4 first-resource then-resource

       primitive
           The primitive command describes a resource. It may be referenced
           only once in group, clone, or master-slave objects. If it’s not
           referenced, then it is placed as a single resource in the CIB.

           Operations may be specified anonymously, as a group or by
           reference:

           ·   "Anonymous", as a list of op specifications. Use this method if
               you don’t need to reference the set of operations elsewhere.
               This is the most common way to define operations.

           ·   If reusing operation sets is desired, use the operations
               keyword along with an id to give the operations set a name. Use
               the operations keyword and an id-ref value set to the id of
               another operations set, to apply the same set of operations to
               this primitive.

           Operation attributes which are not recognized are saved as instance
           attributes of that operation. A typical example is OCF_CHECK_LEVEL.

           For multistate resources, roles are specified as role=<role>.

           A template may be defined for resources which are of the same type
           and which share most of the configuration. See rsc_template for
           more information.

           Attributes containing time values, such as the interval attribute
           on operations, are configured either as a plain number, which is
           interpreted as a time in seconds, or using one of the following
           suffixes:

           ·   s, sec - time in seconds (same as no suffix)

           ·   ms, msec - time in milliseconds

           ·   us, usec - time in microseconds

           ·   m, min - time in minutes

           ·   h, hr - time in hours

           Usage:

               primitive <rsc> {[<class>:[<provider>:]]<type>|@<template>}
                 [description=<description>]
                 [[params] attr_list]

                 params 1: interface=eth0 port=9999

       property
           Set cluster configuration properties. To list the available cluster
           configuration properties, use the ra info command with pengine,
           crmd, cib and stonithd as arguments.

           For more information on rule expressions, see Syntax: Rule
           expressions.

           Usage:

               property [<set_id>:] [rule ...] <option>=<value> [<option>=<value> ...]

           Example:

               property stonith-enabled=true
               property rule date spec years=2014 stonith-enabled=false

       ptest (simulate)
           Show PE (Policy Engine) motions using ptest(8) or crm_simulate(8).

           A CIB is constructed using the current user edited configuration
           and the status from the running CIB. The resulting CIB is run
           through ptest (or crm_simulate) to show changes which would happen
           if the configuration is committed.

           The status section may be loaded from another source and modified
           using the cibstatus level commands. In that case, the ptest command
           will issue a message informing the user that the Policy Engine
           graph is not calculated based on the current status section and
           therefore won’t show what would happen to the running but some
           imaginary cluster.

           If you have graphviz installed and X11 session, dotty(1) is run to
           display the changes graphically.

           Add a string of v characters to increase verbosity. ptest can also
           show allocation scores. utilization turns on information about the
           remaining capacity of nodes. With the actions option, ptest will
           print all resource actions.

           The ptest program has been replaced by crm_simulate in newer
           Pacemaker versions. In some installations both could be installed.
           Use simulate to enfore using crm_simulate.

           Usage:

               ptest [nograph] [v...] [scores] [actions] [utilization]

           Examples:

               ptest scores
               ptest vvvvv
               simulate actions

       refresh
           Refresh the internal structures from the CIB. All changes made
           during this session are lost.

           Usage:

               refresh

       rename
           Rename an object. It is recommended to use this command to rename a
           resource, because it will take care of updating all related
           constraints and a parent resource. Changing ids with the edit
           command won’t have the same effect.

           If you want to rename a resource, it must be in the stopped state.

           Usage:

               rename <old_id> <new_id>

       role
           An ACL role is a set of rules which describe access rights to CIB.
           Rules consist of an access right read, write, or deny and a
           specification denoting part of the configuration to which the
           access right applies. The specification can be an XPath or a
           combination of tag and id references. If an attribute is appended,
           then the specification applies only to that attribute of the
           matching element.

           There is a number of shortcuts for XPath specifications. The meta,
           params, and utilization shortcuts reference resource meta
           attributes, parameters, and utilization respectively. The location
           may be used to specify location constraints most of the time to
           allow resource move and unmove commands. The property references
           cluster properties. The node allows reading node attributes.
           nodeattr and nodeutil reference node attributes and node capacity
           (utilization). The status shortcut references the whole status
           section of the CIB. Read access to status is necessary for various
           monitoring tools such as crm_mon(8) (aka crm status).

           For more information on rule expressions, see Syntax: Rule
           expressions.

           Usage:

               role <role-id> rule [rule ...]

               rule :: acl-right cib-spec [attribute:<attribute>]

               acl-right :: read | write | deny

               cib-spec :: xpath-spec | tag-ref-spec
               xpath-spec :: xpath:<xpath> | shortcut
               tag-ref-spec :: tag:<tag> | ref:<id> | tag:<tag> ref:<id>

               shortcut :: meta:<rsc>[:<attr>]
                       params:<rsc>[:<attr>]
                       utilization:<rsc>
                       location:<rsc>
                       property[:<attr>]
                       node[:<node>]
                       nodeattr[:<attr>]
                       nodeutil[:<node>]
                       status

           Example:

               role app1_admin \
                   write meta:app1:target-role \
                   write meta:app1:is-managed \
                   write location:app1 \
                   read ref:app1

       rsc_defaults
           Set defaults for the resource meta attributes.

           For more information on rule expressions, see Syntax: Rule
           expressions.

           Usage:

               rsc_defaults [<set_id>:] [rule ...] <option>=<value> [<option>=<value> ...]

           Example:

               rsc_defaults failure-timeout=3m

       rsc_template
           The rsc_template command creates a resource template. It may be
           referenced in primitives. It is used to reduce large configurations
           with many similar resources.

           Usage:

               rsc_template <name> [<class>:[<provider>:]]<type>
                 [description=<description>]
                 [params attr_list]
                 [meta attr_list]
                 [utilization attr_list]
                 [operations id_spec]
                   [op op_type [<attribute>=<value>...] ...]

               attr_list :: [$id=<id>] <attr>=<val> [<attr>=<val>...] | $id-ref=<id>
               id_spec :: $id=<id> | $id-ref=<id>
               op_type :: start | stop | monitor

           Example:

               rsc_template public_vm Xen \
                 op start timeout=300s \
                 op stop timeout=300s \
                 op monitor interval=30s timeout=60s \
                 op migrate_from timeout=600s \
                 op migrate_to timeout=600s
               primitive xen0 @public_vm \
                 params xmfile=/etc/xen/xen0
               primitive xen1 @public_vm \
                 params xmfile=/etc/xen/xen1

       rsc_ticket
           This constraint expresses dependency of resources on cluster-wide
           attributes, also known as tickets. Tickets are mainly used in
           geo-clusters, which consist of multiple sites. A ticket may be
           granted to a site, thus allowing resources to run there.

           The loss-policy attribute specifies what happens to the resource
           (or resources) if the ticket is revoked. The default is either stop
           or demote depending on whether a resource is multi-state.

           See also the site set of commands.

           Usage:

               rsc_ticket <id> <ticket_id>: <rsc>[:<role>] [<rsc>[:<role>] ...]
                 [loss-policy=<loss_policy_action>]

               loss_policy_action :: stop | demote | fence | freeze

           Example:

               rsc_ticket ticket-A_public-ip ticket-A: public-ip
               rsc_ticket ticket-A_bigdb ticket-A: bigdb loss-policy=fence
               rsc_ticket ticket-B_storage ticket-B: drbd-a:Master drbd-b:Master

       rsctest
           Test resources with current resource configuration. If no nodes are
           specified, tests are run on all known nodes.

           The order of resources is significant: it is assumed that later
           resources depend on earlier ones.

           If a resource is multi-state, it is assumed that the role on which
           later resources depend is master.

           Tests are run sequentially to prevent running the same resource on
           two or more nodes. Tests are carried out only if none of the
           specified nodes currently run any of the specified resources.
           However, it won’t verify whether resources run on the other nodes.

           Superuser privileges are obviously required: either run this as
           root or setup the sudoers file appropriately.

           Note that resource testing may take some time.

           Usage:

               rsctest <rsc_id> [<rsc_id> ...] [<node_id> ...]

           Examples:

               rsctest my_ip websvc
               rsctest websvc nodeB

       save
           Save the current configuration to a file. Optionally, as XML. Use -
           instead of file name to write the output to stdout.

           The save command accepts the same selection arguments as the show
           command. See the help section for show for more details.

           Usage:

               save [xml] [<id> | type:<type | tag:<tag> |
                           related:<obj> | changed ...] <file>

           Example:

               save myfirstcib.txt
               save web-server server-config.txt

       schema
           CIB’s content is validated by a RNG schema. Pacemaker supports
           several, depending on version. At least the following schemas are
           accepted by crmsh:

           ·   pacemaker-1.0

           ·   pacemaker-1.1

           ·   pacemaker-1.2

           ·   pacemaker-1.3

           ·   pacemaker-2.0

           Use this command to display or switch to another RNG schema.

           Usage:

               schema [<schema>]

           Example:

               schema pacemaker-1.1

       set
           Set the value of a configured attribute. The attribute must have a
           value configured previously, and can be an agent parameter, meta
           attribute or utilization value.

           The first argument to the command is a path to an attribute. This
           is a dot-separated sequence beginning with the name of the
           resource, and ending with the name of the attribute to set.

           Usage:

               set <path> <value>

           Examples:

               set vip1.ip 192.168.20.5
               set vm-a.force_stop 1

       show
           The show command displays CIB objects. Without any argument, it
           displays all objects in the CIB, but the set of objects displayed
           by show can be limited to only objects with the given IDs or by
           using one or more of the special prefixes described below.

           The XML representation for the objects can be displayed by passing
           xml as the first argument.

           To show one or more specific objects, pass the object IDs as
           arguments.

           To show all objects of a certain type, use the type: prefix.

           To show all objects in a tag, use the tag: prefix.

           To show all constraints related to a primitive, use the related:
           prefix.

           To show all modified objects, pass the argument changed.

           The prefixes can be used together on a single command line. For
           example, to show both the tag itself and the objects tagged by it
           the following combination can be used: show tag:my-tag my-tag.

           Usage:

               show [xml] [<id>
                          | changed
                          | type:<type>
                          | tag:<id>
                          | related:<obj>
                          ...]

               type :: node | primitive | group | clone | ms | rsc_template
                     | location | colocation | order
                     | rsc_ticket
                     | property | rsc_defaults | op_defaults
                     | fencing_topology
                     | role | user | acl_target
                     | tag

           Example:

               show webapp
               show type:primitive
               show xml tag:db tag:fs
               show related:webapp

       show-property
           Show the value of the given property. If the value is not set, the
           command will print the default value for the property, if known.

           If no property name is passed to the command, the list of known
           cluster properties is printed.

           If the property is set multiple times, for example using multiple
           property sets with different rule expressions, the output of this
           command is undefined.

           Pass the argument -t or --true to show-property to translate the
           argument value into true or false. If the value is not set, the
           command will print false.

           Usage:

               show-property [-t|--true] [<name>]

           Example:

               show-property stonith-enabled
               show-property -t maintenance-mode

       tag
           Define a resource tag. A tag is an id referring to one or more
           resources, without implying any constraints between the tagged
           resources. This can be useful for grouping conceptually related
           resources.

           Usage:

               tag <tag-name>: <rsc> [<rsc> ...]
               tag <tag-name> <rsc> [<rsc> ...]

           Example:

               tag web: p-webserver p-vip
               tag ips server-vip admin-vip

       template
           The specified template is loaded into the editor. It’s up to the
           user to make a good CRM configuration out of it. See also the
           template section.

           Usage:

               template [xml] url

           Example:

               template two-apaches.txt

       upgrade
           Attempts to upgrade the CIB to validate with the current version.
           Commonly, this is required if the error CIB not supported occurs.
           It typically means that the active CIB version is coming from an
           older release.

           As a safety precaution, the force argument is required if the
           validation-with attribute is set to anything other than 0.6. Thus
           in most cases, it is required.

           Usage:

               upgrade [force]

           Example:

               upgrade force

       user
           Users which normally cannot view or manage cluster configuration
           can be allowed access to parts of the CIB. The access is defined by
           a set of read, write, and deny rules as in role definitions or by
           referencing roles. The latter is considered best practice.

           For more information on rule expressions, see Syntax: Rule
           expressions.

           Usage:

               user <uid> {roles|rules}

               roles :: role:<role-ref> [role:<role-ref> ...]
               rules :: rule [rule ...]

           Example:

               user joe \
                   role:app1_admin \
                   role:read_all

       validate-all
           Call the validate-all action for the resource, if possible.

           Limitations:

           ·   The resource agent must implement the validate-all action.

           ·   The current user must be root.

           ·   The primitive resource must not use nvpair references.

           Usage:

               validate-all <rsc>

       verify
           Verify the contents of the CIB which would be committed.

           Usage:

               verify

       xml
           Even though we promissed no xml, it may happen, but hopefully very
           very seldom, that an element from the CIB cannot be rendered in the
           configuration language. In that case, the element will be shown as
           raw xml, prefixed by this command. That element can then be edited
           like any other. If the shell finds out that after the change it can
           digest it, then it is going to be converted into the normal
           configuration language. Otherwise, there is no need to use xml for
           configuration.

           Usage:

               xml <xml>

   template - Import configuration from templates
       User may be assisted in the cluster configuration by templates prepared
       in advance. Templates consist of a typical ready configuration which
       may be edited to suit particular user needs.

       This command enters a template level where additional commands for
       configuration/template management are available.

       apply
           Copy the current or given configuration to the current CIB. By
           default, the CIB is replaced, unless the method is set to "update".

           Usage:

               apply [<method>] [<config>]

               method :: replace | update

       delete
           Remove a configuration. The loaded (active) configuration may be
           removed by force.

           Usage:

               delete <config> [force]

       edit
           Edit current or given configuration using your favourite editor.

           Usage:

               edit [<config>]

       list
           When called with no argument, lists existing templates and
           configurations.

           Given the argument templates, lists the available templates.

           Given the argument configs, lists the available configurations.

           Usage:

               list [templates|configs]

       load
           Load an existing configuration. Further edit, show, and apply
           commands will refer to this configuration.

           Usage:

               load <config>

       new
           Create a new configuration from one or more templates. Note that
           configurations and templates are kept in different places, so it is
           possible to have a configuration name equal a template name.

           If you already know which parameters are required, you can set them
           directly on the command line.

           The parameter name id is set by default to the name of the
           configuration.

           If no parameters are being set and you don’t want a particular name
           for your configuration, you can call this command with a template
           name as the only parameter. A unique configuration name based on
           the template name will be generated.

           Usage:

               new [<config>] <template> [<template> ...] [params name=value ...]

           Example:

               new vip virtual-ip
               new bigfs ocfs2 params device=/dev/sdx8 directory=/bigfs
               new apache

       show
           Process the current or given configuration and display the result.

           Usage:

               show [<config>]

   cibstatus - CIB status management and editing
       The status section of the CIB keeps the current status of nodes and
       resources. It is modified only on events, i.e. when some resource
       operation is run or node status changes. For obvious reasons, the CRM
       has no user interface with which it is possible to affect the status
       section. From the user’s point of view, the status section is
       essentially a read-only part of the CIB. The current status is never
       even written to disk, though it is available in the PE (Policy Engine)
       input files which represent the history of cluster motions. The current
       status may be read using the cibadmin -Q command.

       It may sometimes be of interest to see how status changes would affect
       the Policy Engine. The set of ‘cibstatus` level commands allow the user
       to load status sections from various sources and then insert or modify
       resource operations or change nodes’ state.

       The effect of those changes may then be observed by running the ptest
       command at the configure level or simulate and run commands at this
       level. The ptest runs with the user edited CIB whereas the latter two
       commands run with the CIB which was loaded along with the status
       section.

       The simulate and run commands as well as all status modification
       commands are implemented using crm_simulate(8).

       load
           Load a status section from a file, a shadow CIB, or the running
           cluster. By default, the current (live) status section is modified.
           Note that if the live status section is modified it is not going to
           be updated if the cluster status changes, because that would
           overwrite the user changes. To make crm drop changes and resume use
           of the running cluster status, run load live.

           All CIB shadow configurations contain the status section which is a
           snapshot of the status section taken at the time the shadow was
           created. Obviously, this status section doesn’t have much to do
           with the running cluster status, unless the shadow CIB has just
           been created. Therefore, the ptest command by default uses the
           running cluster status section.

           Usage:

               load {<file>|shadow:<cib>|live}

           Example:

               load bug-12299.xml
               load shadow:test1

       node
           Change the node status. It is possible to throw a node out of the
           cluster, make it a member, or set its state to unclean.

           online
               Set the node_state crmd attribute to online and the expected
               and join attributes to member. The effect is that the node
               becomes a cluster member.

           offline
               Set the node_state crmd attribute to offline and the expected
               attribute to empty. This makes the node cleanly removed from
               the cluster.

           unclean
               Set the node_state crmd attribute to offline and the expected
               attribute to member. In this case the node has unexpectedly
               disappeared.

           Usage:

               node <node> {online|offline|unclean}

           Example:

               node xen-b unclean

       op
           Edit the outcome of a resource operation. This way you can tell CRM
           that it ran an operation and that the resource agent returned
           certain exit code. It is also possible to change the operation’s
           status. In case the operation status is set to something other than
           done, the exit code is effectively ignored.

           Usage:

               op <operation> <resource> <exit_code> [<op_status>] [<node>]

               operation :: probe | monitor[:<n>] | start | stop |
                  promote | demote | notify | migrate_to | migrate_from
               exit_code :: <rc> | success | generic | args |
                  unimplemented | perm | installed | configured | not_running |
                  master | failed_master
               op_status :: pending | done | cancelled | timeout | notsupported | error

               n :: the monitor interval in seconds; if omitted, the first
                  recurring operation is referenced
               rc :: numeric exit code in range 0..9

           Example:

               op start d1 xen-b generic
               op start d1 xen-b 1
               op monitor d1 xen-b not_running
               op stop d1 xen-b 0 timeout

       origin
           Show the origin of the status section currently in use. This
           essentially shows the latest load argument.

           Usage:

               origin

       quorum
           Set the quorum value.

           Usage:

               quorum <bool>

           Example:

               quorum false

       run
           Run the policy engine with the edited status section.

           Add a string of v characters to increase verbosity. Specify scores
           to see allocation scores also. utilization turns on information
           about the remaining capacity of nodes.

           If you have graphviz installed and X11 session, dotty(1) is run to
           display the changes graphically.

           Usage:

               run [nograph] [v...] [scores] [utilization]

           Example:

               run

       save
           The current internal status section with whatever modifications
           were performed can be saved to a file or shadow CIB.

           If the file exists and contains a complete CIB, only the status
           section is going to be replaced and the rest of the CIB will remain
           intact. Otherwise, the current user edited configuration is saved
           along with the status section.

           Note that all modifications are saved in the source file as soon as
           they are run.

           Usage:

               save [<file>|shadow:<cib>]

           Example:

               save bug-12299.xml

       show
           Show the current status section in the XML format. Brace yourself
           for some unreadable output. Add changed option to get a human
           readable output of all changes.

           Usage:

               show [changed]

       simulate
           Run the policy engine with the edited status section and simulate
           the transition.

           Add a string of v characters to increase verbosity. Specify scores
           to see allocation scores also. utilization turns on information
           about the remaining capacity of nodes.

           If you have graphviz installed and X11 session, dotty(1) is run to
           display the changes graphically.

           Usage:

               simulate [nograph] [v...] [scores] [utilization]

           Example:

               simulate

       ticket
           Modify the ticket status. Tickets can be granted and revoked.
           Granted tickets could be activated or put in standby.

           Usage:

               ticket <ticket> {grant|revoke|activate|standby}

           Example:

               ticket ticketA grant

   assist - Configuration assistant
       The assist sublevel is a collection of helper commands that create or
       modify resources and constraints, to simplify the creation of certain
       configurations.

       For more information on individual commands, see the help text for
       those commands.

       template
           This command takes a list of primitives as argument, and creates a
           new rsc_template for these primitives. It can only do this if the
           primitives do not already share a template and are of the same
           type.

           Usage:

               template primitive-1 primitive-2 primitive-3

       weak-bond
           A colocation between a group of resources says that the resources
           should be located together, but it also means that those resources
           are dependent on each other. If one of the resources fails, the
           others will be restarted.

           If this is not desired, it is possible to circumvent: By placing
           the resources in a non-sequential set and colocating the set with a
           dummy resource which is not monitored, the resources will be placed
           together but will have no further dependency on each other.

           This command creates both the constraint and the dummy resource
           needed for such a colocation.

           Usage:

               weak-bond resource-1 resource-2

   maintenance - Maintenance mode commands
       Maintenance mode commands are commands that manipulate resources
       directly without going through the cluster infrastructure. Therefore,
       it is essential to ensure that the cluster does not attempt to monitor
       or manipulate the resources while these commands are being executed.

       To ensure this, these commands require that maintenance mode is set
       either for the particular resource, or for the whole cluster.

       on
           Enables maintenances mode, either for the whole cluster or for the
           given resource.

           Usage:

               on
               on <rsc>

           Example:

               on rsc1

       off
           Disables maintenances mode, either for the whole cluster or for the
           given resource.

           Usage:

               off
               off <rsc>

           Example:

               off rsc1

       action
           Invokes the given action for the resource. This is done directly
           via the resource agent, so the command must be issued while the
           cluster or the resource is in maintenance mode.

           Unless the action is start or monitor, the action must be invoked
           on the same node as where the resource is running. If the resource
           is running on multiple nodes, the command will fail.

           To use SSH for executing resource actions on multiple nodes, append
           ssh after the action name. This requires SSH access to be
           configured between the nodes and the parallax python package to be
           installed.

           Usage:

               action <rsc> <action>
               action <rsc> <action> ssh

           Example:

               action webserver reload
               action webserver monitor ssh

   history - Cluster history
       Examining Pacemaker’s history is a particularly involved task. The
       number of subsystems to be considered, the complexity of the
       configuration, and the set of various information sources, most of
       which are not exactly human readable, keep analyzing resource or node
       problems accessible to only the most knowledgeable. Or, depending on
       the point of view, to the most persistent. The following set of
       commands has been devised in hope to make cluster history more
       accessible.

       Of course, looking at all history could be time consuming regardless of
       how good the tools at hand are. Therefore, one should first say which
       period he or she wants to analyze. If not otherwise specified, the last
       hour is considered. Logs and other relevant information is collected
       using crm report. Since this process takes some time and we always need
       fresh logs, information is refreshed in a much faster way using the
       python parallax module. If python-parallax is not found on the system,
       examining a live cluster is still possible — though not as comfortable.

       Apart from examining a live cluster, events may be retrieved from a
       report generated by crm report (see also the -H option). In that case
       we assume that the period stretching the whole report needs to be
       investigated. Of course, it is still possible to further reduce the
       time range.

       If you have discovered an issue that you want to show someone else, you
       can use the session pack command to save the current session as a
       tarball, similar to those generated by crm report.

       In order to minimize the size of the tarball, and to make it easier for
       others to find the interesting events, it is recommended to limit the
       time frame which the saved session covers. This can be done using the
       timeframe command (example below).

       It is also possible to name the saved session using the session save
       command.

       Example:

           crm(live)history# timeframe "Jul 18 12:00" "Jul 18 12:30"
           crm(live)history# session save strange_restart
           crm(live)history# session pack
           Report saved in .../strange_restart.tar.bz2
           crm(live)history#

       detail
           How much detail to show from the logs. Valid detail levels are
           either 0 or 1, where 1 is the highest detail level. The default
           detail level is 0.

           Usage:

               detail <detail_level>

               detail_level :: small integer (defaults to 0)

           Example:

               detail 1

       diff
           A transition represents a change in cluster configuration or state.
           Use diff to see what has changed between two transitions.

           If you want to specify the current cluster configuration and
           status, use the string live.

           Normally, the first transition specified should be the one which is
           older, but we are not going to enforce that.

           Note that a single configuration update may result in more than one
           transition.

           Usage:

               diff <pe> <pe> [status] [html]

               pe :: <number>|<index>|<file>|live

           Examples:

               diff 2066 2067
               diff pe-input-2080.bz2 live status

       exclude
           If a log is infested with irrelevant messages, those messages may
           be excluded by specifying a regular expression. The regular
           expressions used are Python extended. This command is additive. To
           drop all regular expressions, use exclude clear. Run exclude only
           to see the current list of regular expressions. Excludes are saved
           along with the history sessions.

           Usage:

               exclude [<regex>|clear]

           Example:

               exclude kernel.*ocfs2

       graph
           Create a graphviz graphical layout from the PE file (the
           transition). Every transition contains the cluster configuration
           which was active at the time. See also generate a directed graph
           from configuration.

           Usage:

               graph <pe> [<gtype> [<file> [<img_format>]]]

               gtype :: dot
               img_format :: `dot` output format (see the +-T+ option)

           Example:

               graph -1
               graph 322 dot clu1.conf.dot
               graph 322 dot clu1.conf.svg svg

       info
           The info command provides a summary of the information source,
           which can be either a live cluster snapshot or a previously
           generated report.

           Usage:

               info

           Example:

               info

       latest
           The latest command shows a bit of recent history, more precisely
           whatever happened since the last cluster change (the latest
           transition). If the transition is running, the shell will first
           wait until it finishes.

           Usage:

               latest

           Example:

               latest

       limit (timeframe)
           This command can be used to modify the time span to examine. All
           history commands look at events within a certain time span.

           For the live source, the default time span is the last hour.

           There is no time span limit for the hb_report source.

           The time period is parsed by the dateutil python module. It covers
           a wide range of date formats. For instance:

           ·   3:00 (today at 3am)

           ·   2010/9/1 2pm (September 1st 2010 at 2pm)

           For more examples of valid time/date statements, please refer to
           the python-dateutil documentation:

           ·   dateutil.readthedocs.org

           If the dateutil module is not available, then the time is parsed
           using strptime and only the kind as printed by date(1) is allowed:

           ·   Tue Sep 15 20:46:27 CEST 2010

           Usage:

               limit [<from_time>] [<to_time>]

           Examples:

               limit 10:15
               limit 15h22m 16h
               limit "Sun 5 20:46" "Sun 5 22:00"

       log
           Show messages logged on one or more nodes. Leaving out a node name
           produces combined logs of all nodes. Messages are sorted by time
           and, if the terminal emulations supports it, displayed in different
           colours depending on the node to allow for easier reading.

           The sorting key is the timestamp as written by syslog which
           normally has the maximum resolution of one second. Obviously,
           messages generated by events which share the same timestamp may not
           be sorted in the same way as they happened. Such close events may
           actually happen fairly often.

           Usage:

               log [<node> [<node> ...] ]

           Example:

               log node-a

       events
           By analysing the log output and looking for particular patterns,
           the events command helps sifting through the logs to find when
           particular events like resources changing state or node failure may
           have occurred.

           This can be used to generate a combined list of events from all
           nodes.

           Usage:

               events

           Example:

               events

       node
           Show important events that happened on a node. Important events are
           node lost and join, standby and online, and fence. Use either node
           names or extended regular expressions.

           Usage:

               node <node> [<node> ...]

           Example:

               node node1

       peinputs
           Every event in the cluster results in generating one or more Policy
           Engine (PE) files. These files describe future motions of
           resources. The files are listed as full paths in the current report
           directory. Add v to also see the creation time stamps.

           Usage:

               peinputs [{<range>|<number>} ...] [v]

               range :: <n1>:<n2>

           Example:

               peinputs
               peinputs 440:444 446
               peinputs v

       refresh
           This command makes sense only for the live source and makes crm
           collect the latest logs and other relevant information from the
           logs. If you want to make a completely new report, specify force.

           Usage:

               refresh [force]

       resource
           Show actions and any failures that happened on all specified
           resources on all nodes. Normally, one gives resource names as
           arguments, but it is also possible to use extended regular
           expressions. Note that neither groups nor clones or master/slave
           names are ever logged. The resource command is going to expand all
           of these appropriately, so that clone instances or resources which
           are part of a group are shown.

           Usage:

               resource <rsc> [<rsc> ...]

           Example:

               resource bigdb public_ip
               resource my_.*_db2
               resource ping_clone

       session
           Sometimes you may want to get back to examining a particular
           history period or bug report. In order to make that easier, the
           current settings can be saved and later retrieved.

           If the current history being examined is coming from a live cluster
           the logs, PE inputs, and other files are saved too, because they
           may disappear from nodes. For the existing reports coming from
           hb_report, only the directory location is saved (not to waste
           space).

           A history session may also be packed into a tarball which can then
           be sent to support.

           Leave out subcommand to see the current session.

           Usage:

               session [{save|load|delete} <name> | pack [<name>] | update | list]

           Examples:

               session save bnc966622
               session load rsclost-2
               session list

       setnodes
           In case the host this program runs on is not part of the cluster,
           it is necessary to set the list of nodes.

           Usage:

               setnodes node <node> [<node> ...]

           Example:

               setnodes node_a node_b

       show
           Every transition is saved as a PE file. Use this command to render
           that PE file either as configuration or status. The configuration
           output is the same as crm configure show.

           Usage:

               show <pe> [status]

               pe :: <number>|<index>|<file>|live

           Examples:

               show 2066
               show pe-input-2080.bz2 status

       source
           Events to be examined can come from the current cluster or from a
           hb_report report. This command sets the source. source live sets
           source to the running cluster and system logs. If no source is
           specified, the current source information is printed.

           In case a report source is specified as a file reference, the file
           is going to be unpacked in place where it resides. This directory
           is not removed on exit.

           Usage:

               source [<dir>|<file>|live]

           Examples:

               source live
               source /tmp/customer_case_22.tar.bz2
               source /tmp/customer_case_22
               source

       transition
           This command will print actions planned by the PE and run graphviz
           (dotty) to display a graphical representation of the transition. Of
           course, for the latter an X11 session is required. This command
           invokes ptest(8) in background.

           The showdot subcommand runs graphviz (dotty) to display a graphical
           representation of the .dot file which has been included in the
           report. Essentially, it shows the calculation produced by pengine
           which is installed on the node where the report was produced. In
           optimal case this output should not differ from the one produced by
           the locally installed pengine.

           The log subcommand shows the full log for the duration of the
           transition.

           A transition can also be saved to a CIB shadow for further analysis
           or use with cib or configure commands (use the save subcommand).
           The shadow file name defaults to the name of the PE input file.

           If the PE input file number is not provided, it defaults to the
           last one, i.e. the last transition. The last transition can also be
           referenced with number 0. If the number is negative, then the
           corresponding transition relative to the last one is chosen.

           If there are warning and error PE input files or different nodes
           were the DC in the observed timeframe, it may happen that PE input
           file numbers collide. In that case provide some unique part of the
           path to the file.

           After the ptest output, logs about events that happened during the
           transition are printed.

           The tags subcommand scans the logs for the transition and return a
           list of key events during that transition. For example, the tag
           error will be returned if there are any errors logged during the
           transition.

           Usage:

               transition [<number>|<index>|<file>] [nograph] [v...] [scores] [actions] [utilization]
               transition showdot [<number>|<index>|<file>]
               transition log [<number>|<index>|<file>]
               transition save [<number>|<index>|<file> [name]]
               transition tags [<number>|<index>|<file>]

           Examples:

               transition
               transition 444
               transition -1
               transition pe-error-3.bz2
               transition node-a/pengine/pe-input-2.bz2
               transition showdot 444
               transition log
               transition save 0 enigma-22

       wdiff
           A transition represents a change in cluster configuration or state.
           Use wdiff to see what has changed between two transitions as word
           differences on a line-by-line basis.

           If you want to specify the current cluster configuration and
           status, use the string live.

           Normally, the first transition specified should be the one which is
           older, but we are not going to enforce that.

           Note that a single configuration update may result in more than one
           transition.

           Usage:

               wdiff <pe> <pe> [status]

               pe :: <number>|<index>|<file>|live

           Examples:

               wdiff 2066 2067
               wdiff pe-input-2080.bz2 live status

   report
       Interface to a tool for creating a cluster report. A report is an
       archive containing log files, configuration files, system information
       and other relevant data for a given time period. This is a useful tool
       for collecting data to attach to bug reports, or for detecting the root
       cause of errors resulting in resource failover, for example.

       See crmsh_hb_report(8) for more details on arguments, or call crm
       report -h

       Usage:

           report -f {time|"cts:"testnum} [-t time] [-u user] [-l file]
                  [-n nodes] [-E files] [-p patt] [-L patt] [-e prog]
                  [-MSDZAVsvhd] [dest]

       Examples:

           report -f 2pm report_1
           report -f "2007/9/5 12:30" -t "2007/9/5 14:00" report_2
           report -f 1:00 -t 3:00 -l /var/log/cluster/ha-debug report_3
           report -f "09sep07 2:00" -u hbadmin report_4
           report -f 18:00 -p "usern.*" -p "admin.*" report_5
           report -f cts:133 ctstest_133

   end (cd, up)
       The end command ends the current level and the user moves to the parent
       level. This command is available everywhere.

       Usage:

           end

   help
       The help command prints help for the current level or for the specified
       topic (command). This command is available everywhere.

       Usage:

           help [<topic>]

   quit (exit, bye)
       Leave the program.

BUGS

       Even though all sensible configurations (and most of those that are
       not) are going to be supported by the crm shell, I suspect that it may
       still happen that certain XML constructs may confuse the tool. When
       that happens, please file a bug report.

       The crm shell will not try to update the objects it does not
       understand. Of course, it is always possible to edit such objects in
       the XML format.
