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. Using this type also implies the use of --mergedconfig option. 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.
- --sinceversion 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).
This option is currently applicable only with --type new
to display all configuration settings introduced since given version.
- --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.
