LVMCONFIG(8) System Manager's Manual LVMCONFIG(8)
lvmconfig - Display and manipulate configuration information
lvmconfig
[ option_args ]
[ position_args ]
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.

[ COMMON_OPTIONS ]
[ String ... ]
Common options for lvm:
[ -d|--debug ]
[ -h|--help ]
[ -q|--quiet ]
[ -t|--test ]
[ -v|--verbose ]
[ -y|--yes ]
[ --commandprofile String ]
[ --config String ]
[ --driverloaded y|n ]
[ --longhelp ]
[ --profile String ]
[ --version ]
--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.
--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.)
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.)
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.
