NAME

       lvmconfig - Display and manipulate configuration information

SYNOPSIS

       lvmconfig
           [ option_args ]
           [ position_args ]

DESCRIPTION

       lvmconfig,  lvm  config,  lvm  dumpconfig (for compatibility reasons, to be phased out) produce formatted
       output from the LVM configuration tree. The sources of the configuration  data  include  lvm.conf(5)  and
       command line settings from --config.

           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]
           [ -t|--test ]

           [    --longhelp ]
           [    --profile String ]
           [    --version ]

OPTIONS

       --atversion String
              Specify an LVM version in x.y.z format where x is the major version, the y is the minor version
              and z is the patchlevel (e.g. 2.2.106).  When configuration is displayed, the configuration
              settings recognized at this LVM version will be considered only. This can be used to display a
              configuration that a certain LVM version understands and which does not contain any newer settings
              for which LVM would issue a warning message when checking the configuration.

       --commandprofile String
              The command profile to use for command configuration.  See lvm.conf(5) for more information about
              profiles.

       --config String
              Config settings for the command. These override lvm.conf settings.  The String arg uses the same
              format as lvm.conf, or may use section/field syntax.  See lvm.conf(5) for more information about
              config.

       -d|--debug ...
              Set debug level. Repeat from 1 to 6 times to increase the detail of messages sent to the log file
              and/or syslog (if configured).

       --driverloaded y|n
              If set to no, the command will not attempt to use device-mapper.  For testing and debugging.

       -f|--file String
              Write output to the named file.

       -h|--help
              Display help text.

       --ignoreadvanced
              Exclude advanced configuration settings from the output.

       --ignorelocal
              Ignore the local section. The local section should be defined in the lvmlocal.conf file, and
              should contain config settings specific to the local host which should not be copied to other
              hosts.

       --ignoreunsupported
              Exclude unsupported configuration settings from the output. These settings are either used for
              debugging and development purposes only or their support is not yet complete and they are not
              meant to be used in production. The current and diff types include unsupported settings in their
              output by default, all the other types ignore unsupported settings.

       -l|--list
              List config settings with summarizing comment. This is the same as using options --typeconfig list
              --withsummary.

       --longhelp
              Display long help text.

       --mergedconfig
              When the command is run with --config and/or --commandprofile (or using LVM_COMMAND_PROFILE
              environment variable), --profile, or --metadataprofile, merge all the contents of the "config
              cascade" before displaying it.  Without merging, only the configuration at the front of the
              cascade is displayed.  See lvm.conf(5) for more information about config.

       --metadataprofile String
              The metadata profile to use for command configuration.  See lvm.conf(5) for more information about
              profiles.

       --profile String
              An alias for --commandprofile or --metadataprofile, depending on the command.

       -q|--quiet ...
              Suppress output and log messages. Overrides --debug and --verbose.  Repeat once to also suppress
              any prompts with answer 'no'.

       --showdeprecated
              Include deprecated configuration settings in the output. These settings are deprecated after a
              certain version. If a concrete version is specified with --atversion, deprecated settings are
              automatically included if the specified version is lower than the version in which the settings
              were deprecated. The current and diff types include deprecated settings in their output by
              default, all the other types ignore deprecated settings.

       --showunsupported
              Include unsupported configuration settings in the output. These settings are either used for
              debugging or development purposes only, or their support is not yet complete and they are not
              meant to be used in production. The current and diff types include unsupported settings in their
              output by default, all the other types ignore unsupported settings.

       --sinceversion String
              Specify an LVM version in x.y.z format where x is the major version, the y is the minor version
              and z is the patchlevel (e.g. 2.2.106).  This option is currently applicable only with
              --typeconfig new to display all configuration settings introduced since given version.

       -t|--test
              Run in test mode. Commands will not update metadata.  This is implemented by disabling all
              metadata writing but nevertheless returning success to the calling function. This may lead to
              unusual error messages in multi-stage operations if a tool relies on reading back metadata it
              believes has changed but hasn't.

       --typeconfig current|default|diff|full|list|missing|new|profilable|profilable-command|profilable-metadata
              current prints the config settings that would be applied to an lvm command (assuming the command
              does not override them on the command line.) This includes: settings that have been modified in
              lvm config files, settings that get their default values from config files, and default settings
              that have been uncommented in config files.  default prints all settings with their default
              values.  Changes made in lvm config files are not reflected in the output.  Some settings get
              their default values internally, and these settings are printed as comments.  Other settings get
              their default values from config files, and these settings are not printed as comments.  diff
              prints only config settings that have been modified from their default values in config files (the
              difference between current and default.)  full prints every setting uncommented and set to the
              current value, i.e. how it would be used by an lvm command.  This includes settings modified in
              config files, settings that usually get defaults internally, and settings that get defaults from
              config files.  list prints all config names without values.  missing prints settings that are
              missing from the lvm config files. A missing setting that usually gets its default from config
              files is printed uncommented and set to the internal default.  Settings that get their default
              internally and are not set in config files are printed commented with the internal default.  new
              prints config settings that have been added since the lvm version specified by --sinceversion.
              They are printed with their default values.  profilable prints settings with their default values
              that can be set from a profile.  profilable-command prints settings with their default values that
              can be set from a command profile.  profilable-metadata prints settings with their default values
              that can be set from a metadata profile.  Also see lvm.conf(5).

       --unconfigured
              Internal option used for generating config file during build.

       --validate
              Validate current configuration used and exit with appropriate return code. The validation is done
              only for the configuration at the front of the "config cascade". To validate the whole merged
              configuration tree, also use --mergedconfig.  The validation is done even if lvm.conf
              config/checks is disabled.

       -v|--verbose ...
              Set verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and
              stderr.

       --version
              Display version information.

       --withcomments
              Display a full comment for each configuration node. For deprecated settings, also display comments
              about deprecation.

       --withgeneralpreamble
              Include general config file preamble.

       --withlocalpreamble
              Include local config file preamble.

       --withspaces
              Where appropriate, add more spaces in output for better readability.

       --withsummary
              Display a one line comment for each configuration node.

       --withversions
              Also display a comment containing the version of introduction for each configuration node. If the
              setting is deprecated, also display the version since which it is deprecated.

       -y|--yes
              Do not prompt for confirmation interactively but always assume the answer yes. Use with extreme
              caution.  (For automatic no, see -qq.)

VARIABLES

       String
              See the option description for information about the string content.

       Size[UNIT]
              Size is an input number that accepts an optional unit.  Input units are always treated as base two
              values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024.  The default input unit
              is  specified  by  letter,  followed  by  |UNIT.   UNIT  represents  other  possible  input units:
              bBsSkKmMgGtTpPeE.  b|B is bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is  megabytes,
              g|G  is  gigabytes,  t|T  is  terabytes,  p|P  is petabytes, e|E is exabytes.  (This should not be
              confused with the output control --units, where capital letters mean multiple of 1000.)

ENVIRONMENT VARIABLES

       See lvm(8) for information about environment  variables  used  by  lvm.   For  example,  LVM_VG_NAME  can
       generally be substituted for a required VG parameter.
