OPTIONS
--addtag Tag
Adds a tag to a PV, VG or LV. This option can be repeated to add multiple tags at
once. See lvm(8) for information about tags.
-a|--all
Change all visible PVs.
-x|--allocatable y|n
Enable or disable allocation of physical extents on this PV.
-A|--autobackup y|n
Specifies if metadata should be backed up automatically after a change. Enabling
this is strongly advised! See vgcfgbackup(8) for more information.
--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).
--deltag Tag
Deletes a tag from a PV, VG or LV. This option can be repeated to delete multiple
tags at once. See lvm(8) for information about tags.
--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|--force ...
Override various checks, confirmations and protections. Use with extreme caution.
-h|--help
Display help text.
--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.
--lockopt String
Used to pass options for special cases to lvmlockd. See lvmlockd(8) for more
information.
--longhelp
Display long help text.
--metadataignore y|n
Specifies the metadataignore property of a PV. If yes, metadata areas on the PV
are ignored, and lvm will not store metadata in the metadata areas of the PV. If
no, lvm will store metadata on the PV.
--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'.
--reportformat basic|json
Overrides current output format for reports which is defined globally by the
report/output_format setting in lvm.conf(5). basic is the original format with
columns and rows. If there is more than one report per command, each report is
prefixed with the report name for identification. json produces report output in
JSON format. See lvmreport(7) for more information.
-S|--select String
Select objects for processing and reporting based on specified criteria. The
criteria syntax is described by --select help and lvmreport(7). For reporting
commands, one row is displayed for each object matching the criteria. See
--options help for selectable object fields. Rows can be displayed with an
additional "selected" field (-o selected) showing 1 if the row matches the
selection and 0 otherwise. For non-reporting commands which process LVM entities,
the selection is used to choose items to process.
-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.
-u|--uuid
Generate new random UUID for specified PVs.
-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.
-y|--yes
Do not prompt for confirmation interactively but always assume the answer yes. Use
with extreme caution. (For automatic no, see -qq.)
VARIABLES
PV Physical Volume name, a device path under /dev. For commands managing physical
extents, a PV positional arg generally accepts a suffix indicating a range (or
multiple ranges) of physical extents (PEs). When the first PE is omitted, it
defaults to the start of the device, and when the last PE is omitted it defaults to
end. Start and end range (inclusive): PV[:PE-PE]... Start and length range
(counting from 0): PV[:PE+PE]...
Select Select indicates that a required positional parameter can be omitted if the
--select option is used. No arg appears in this position.
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.
EXAMPLES
Disallow the allocation of physical extents on a PV (e.g. because of disk errors, or
because it will be removed after freeing it).
