DESCRIPTION
lvmconfig produces formatted output from the LVM configuration tree. The command was added in release
2.02.119 and has an identical longer form lvm dumpconfig.
OPTIONS
-f, --file filename
Send output to a file named 'filename'.
-l, --list
List configuration settings with summarizing comment. This is the same as using lvmconfig --type
list --withsummary.
--type {current|default|diff|full|missing|new|profilable|profilable-command|profilable-metadata}
Select the type of configuration to display. The configuration settings displayed have either
default values or currently-used values assigned based on the type selected. If no type is
selected, --type current is used by default. Whenever a configuration setting with a default value
is commented out, it means the setting does not have any concrete default value defined. Output
can be saved and used as a proper lvm.conf(5) file.
current
Display the current lvm.conf configuration merged with any tag config if used. See also
lvm.conf(5) for more info about LVM configuration methods.
default
Display all possible configuration settings with default values assigned.
diff
Display all configuration settings for which the values used differ from defaults. The value
assigned for each configuration setting is the value currently used. This is actually minimal
LVM configuration which can be used without a change to current configured behaviour.
full
Display full configuration tree - a combination of current configuration tree (--type current)
and tree of settings for which default values are used (--type missing). This is exactly the
configuration tree that LVM2 uses during command execution. Using this type also implies the
use of --mergedconfig option. If comments are displayed (see --withcomments and --withsummary
options), then for each setting found in existing configuration and for which defaults are not
used, there's an extra comment line printed to denote this.
list
Display plain list of configuration settings.
missing
Display all configuration settings with default values assigned which are missing in the
configuration currently used and for which LVM automatically fallbacks to using these default
values.
new
Display all new configuration settings introduced in current LVM version or specific version as
defined by --atversion option.
profilable
Display all profilable configuration settings with default values assigned. See lvm.conf(5)
for more info about profile config method.
profilable-command
Display all profilable configuration settings with default values assigned that can be used in
command profile. This is a subset of settings displayed by --type --profilable.
profilable-metadata
Display all profilable configuration settings with default values assigned that can be used in
metadata profile. This is a subset of settings displayed by --type --profilable.
--atversion version
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.
--ignoreadvanced
Exclude advanced configuration settings from the output.
--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.
--ignorelocal
Ignore local section.
--config ConfigurationString
Use ConfigurationString to override existing configuration. This configuration is then applied
for the lvmconfig command itself. See also lvm.conf(5) for more info about config cascade.
--commandprofile ProfileName
Use ProfileName to override existing configuration. This configuration is then applied for the
lvmconfig command itself. See also --mergedconfig option and lvm.conf(5) for more info about
config cascade.
--profile ProfileName
The same as using --commandprofile but the configuration is not applied for the lvmconfig command
itself.
--metadataprofile ProfileName
Use ProfileName to override existing configuration. The configuration defined in metadata profile
has no effect for the lvmconfig command itself. lvmconfig displays the configuration only. See
also --mergedconfig option and lvm.conf(5) for more info about config cascade.
--mergedconfig
When the lvmconfig command is run with the --config option and/or --commandprofile (or using
LVM_COMMAND_PROFILE environment variable), --profile, --metadataprofile option, merge all the
contents of the config cascade before displaying it. Without the --mergeconfig option used, only
the configuration at the front of the cascade is displayed. See also lvm.conf(5) for more info
about config cascade.
--showdeprecated
Include deprecated configuration settings in the output. These settings are always deprecated
since certain version. If concrete version is specified with --atversion option, deprecated
settings are automatically included if specified version is lower that the version in which the
settings were deprecated. The current and diff types include deprecated settings int 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.
--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, use also the --mergedconfig option. The validation is done even if
config/checks lvm.conf(5) option is disabled.
--withsummary
Display a one line comment for each configuration node.
--withcomments
Display a full comment for each configuration node. For deprecated settings, also display comments
about deprecation in addition.
--withspaces
Where appropriate, add more spaces in output for better readability.
--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.
