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 ]
[ --devices PV ]
[ --devicesfile String ]
[ --driverloaded y|n ]
[ --journal String ]
[ --lockopt String ]
[ --longhelp ]
[ --nohints ]
[ --nolocking ]
[ --profile String ]
[ --version ]
--atversion String
Specify an LVM version in x.y.z format where x is the ma‐
jor 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 considered only. This can be used to dis‐
play a configuration that a certain LVM version under‐
stands 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
Devices that the command can use. This option can be re‐
peated 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) de‐
vices/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 de‐
fined 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 out‐
put. These settings are either used for debugging and de‐
velopment 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 unsup‐
ported settings.
--journal String
Record information in the systemd journal. This informa‐
tion 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 --commandpro‐
file (or using LVM_COMMAND_PROFILE environment variable),
--profile, or --metadataprofile, merge all the contents of
the "config cascade" before displaying it. Without merg‐
ing, 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.
--profile String
An alias for --commandprofile or --metadataprofile, de‐
pending 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, depre‐
cated 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 depre‐
cated 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 develop‐
ment purposes only, or their support is not yet complete
and they are not meant to be used in production. The cur‐
rent 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 ma‐
jor 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 config‐
uration 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 nev‐
ertheless returning success to the calling function. This
may lead to unusual error messages in multi-stage opera‐
tions if a tool relies on reading back metadata it be‐
lieves 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 set‐
tings 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 set‐
tings are not printed as comments. diff prints only con‐
fig 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 set‐
tings 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 set‐
ting that usually gets its default from config files is
printed uncommented and set to the internal default. Set‐
tings that get their default internally and are not set in
config files are printed commented with the internal de‐
fault. 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 appro‐
priate 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.
-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 depreca‐
tion.
--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 introduc‐
tion for each configuration node. If the setting is depre‐
cated, also display the version since which it is depre‐
cated.
-y|--yes
Do not prompt for confirmation interactively but always
assume the answer yes. Use with extreme caution. (For au‐
tomatic 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, regard‐
less of capitalization, e.g. 'k' and 'K' both refer to
1024. The default input unit is specified by letter, fol‐
lowed 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 con‐
trol --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.
