--addtag

Adds a tag to a PV, VG or LV. This option can be repeated to add multiple tags at once. See lvm(8) forinformation about tags.

-a|--all

Change all visible PVs.

-x|--allocatable

Enable or disable allocation of physical extents on this PV.

-A|--autobackup

Specifies if metadata should be backed up automatically after a change. Enabling this is stronglyadvised! See vgcfgbackup(8) for more information.

--commandprofile

The command profile to use for command configuration. See lvm.conf(5) for more information about pro‐files.

--config

Config settings for the command. These override lvm.conf settings. The String arg uses the same formatas 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 fileand/or syslog (if configured).

--deltag

Deletes a tag from a PV, VG or LV. This option can be repeated to delete multiple tags at once. Seelvm(8) for information about tags.

--driverloaded

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.

--ignoreskippedcluster

Use to avoid exiting with an non-zero status code if the command is run without clustered locking andclustered VGs are skipped.

--longhelp

Display long help text.

--metadataignore

Specifies the metadataignore property of a PV. If yes, metadata areas on the PV are ignored, and lvmwill not store metadata in the metadata areas of the PV. If no, lvm will store metadata on the PV.

--profile

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 anyprompts with answer 'no'.

--reportformat

Overrides current output format for reports which is defined globally by the report/output_format set‐ting in lvm.conf. basic is the original format with columns and rows. If there is more than onereport per command, each report is prefixed with the report name for identification. json producesreport output in JSON format. See lvmreport(7) for more information.

-S|--select

Select objects for processing and reporting based on specified criteria. The criteria syntax isdescribed by --select help and lvmreport(7). For reporting commands, one row is displayed for eachobject matching the criteria. See --options help for selectable object fields. Rows can be displayedwith an additional "selected" field (-o selected) showing 1 if the row matches the selection and 0 oth‐erwise. For non-reporting commands which process LVM entities, the selection is used to choose itemsto process.

-t|--test

Run in test mode. Commands will not update metadata. This is implemented by disabling all metadatawriting but nevertheless returning success to the calling function. This may lead to unusual error mes‐sages in multi-stage operations if a tool relies on reading back metadata it believes has changed buthasn'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 andstderr.

--version

Display version information.

-y|--yes

Do not prompt for confirmation interactively but always assume the answer yes. Use with extreme cau‐tion. (For automatic no, see -qq.)VARIABLESPVPhysical Volume name, a device path under /dev. For commands managing physical extents, a PV posi‐tional 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 isomitted it defaults to end. Start and end range (inclusive): PV[:PE-PE]... Start and length range(counting from 0): PV[:PE+PE]...SelectSelect indicates that a required positional parameter can be omitted if the --select option is used.No arg appears in this position.StringSee 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 val‐ues, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024. The default input unit isspecified 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 isterabytes, p|P is petabytes, e|E is exabytes. (This should not be confused with the output control
