NAME
lvmconfig — Display and manipulate configuration information
SYNOPSIS
lvmconfig
[ option_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.

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(5) settings. The String
arg uses the same format as lvm.conf(5), 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).
--devices PV
Restricts the devices that are visible and accessible to the command. Devices not
listed will appear to be missing. This option can be repeated, or accepts a comma
separated list of devices. This overrides the devices file.
--devicesfile String
A file listing devices that LVM should use. The file must exist in
/etc/lvm/devices/ and is managed with the lvmdevices(8) command. This overrides
the lvm.conf(5) devices/devicesfile and devices/use_devicesfile settings.
--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.
--journal String
Record information in the systemd journal. This information is in addition to
information enabled by the lvm.conf log/journal setting. command: record
information about the command. output: record the default command output. debug:
record full command debugging.
-l|--list
List config settings with summarizing comment. This is the same as using options
--typeconfig list --withsummary.
--lockopt String
Used to pass options for special cases to lvmlockd. See lvmlockd(8) for more
information.
--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.
--nohints
Do not use the hints file to locate devices for PVs. A command may read more
devices to find PVs when hints are not used. The command will still perform
standard hint file invalidation where appropriate.
--nolocking
Disable locking. Use with caution, concurrent commands may produce incorrect
results.
--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(5) config/checks is disabled.
--valuesonly
When printing config settings, print only values without keys.
-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: b|B is bytes, s|S is sectors of 512
bytes, k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB, p|P is PiB, e|E is EiB.
(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.
