DESCRIPTION
lvmconfig, lvm config, lvm dumpconfig (for compatibility reasons, to be phased out) pro-
duce 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 ]
[ --lockopt String ]
[ --longhelp ]
[ --nolocking ]
[ --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 dis-
played, the configuration settings recognized at this LVM version will be consid-
ered 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 in-
formation 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 ei-
ther 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.
--lockopt String
Used to pass options for special cases to lvmlockd. See lvmlockd(8) for more in-
formation.
--longhelp
Display long help text.
--mergedconfig
When the command is run with --config and/or --commandprofile (or using LVM_COM-
MAND_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.
--nolocking
Disable locking.
--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 depre-
cated 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 com-
plete 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 ap-
plicable only with --typeconfig new to display all configuration settings intro-
duced since given version.
-t|--test
Run in test mode. Commands will not update metadata. This is implemented by dis-
abling all metadata writing but nevertheless returning success to the calling func-
tion. 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|pro-
filable-metadata
current prints the config settings that would be applied to an lvm command (assum-
ing the command does not override them on the command line.) This includes: set-
tings 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 val-
ues internally, and these settings are printed as comments. Other settings get
their default values from config files, and these settings are not printed as com-
ments. 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 com-
mented with the internal default. new prints config settings that have been added
since the lvm version specified by --sinceversion. They are printed with their de-
fault 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 val-
idation is done only for the configuration at the front of the "config cascade". To
validate the whole merged configuration tree, also use --mergedconfig. The valida-
tion 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 configura-
tion 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 re-
fer 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 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.
