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 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(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
Restricts the devices that are visible and accessible to the command. Devices
not listed will appear to be missing. This option can be repeated, 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) devices/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 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.
--journal
String
Record information in the systemd journal. This information 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 --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.
--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. Use with caution, concurrent commands may produce incorrect
results.
--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(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 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
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.)
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 refer to 1024. The default input unit is specified by letter, followed 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 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.SEE ALSO
