-a|--allRemoves all empty PVs if none are named on the command line.
-A|--autobackup y|nSpecifies if metadata should be backed up automatically after a change. Enabling this is strongly advised! See vgcfgbackup(8) for more information.
--commandprofile StringThe command profile to use for command configuration. See lvm.conf(5) for more information about profiles.
--config StringConfig 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|nIf 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|--helpDisplay help text.
--longhelpDisplay long help text.
--mirrorsonlyOnly remove missing PVs from mirror LVs.
--profile StringAn 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'.
--removemissingRemoves all missing PVs from the VG, if there are no LVs allocated on them. This resumes normal operation of the VG (new LVs may again be created, changed and so on). If this is not possible because LVs are referencing the missing PVs, this option can be combined with --force to have the command remove any partial LVs. In this case, any LVs and dependent snapshots that were partly on the missing disks are removed completely, including those parts on disks that are still present. If LVs spanned several disks, including ones that are lost, salvaging some data first may be possible by activating LVs in partial mode.
--reportformat basic|jsonOverrides current output format for reports which is defined globally by the report/output_format setting in lvm.conf. 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.
-t|--testRun 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.
-v|--verbose ...Set verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and stderr.
--versionDisplay version information.
-y|--yesDo not prompt for confirmation interactively but always assume the answer yes. Use with extreme caution. (For automatic no, see -qq.)
VGVolume Group name. See lvm(8) for valid names.
PVPhysical 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]...
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 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: 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 is terabytes, p|P is petabytes, e|E is exabytes. (This should not be confused with the output control --units, where capital letters mean multiple of 1000.)lvm(8) for information about environment variables used by lvm. For example, LVM_VG_NAME can generally be substituted for a required VG parameter. lvm(8) lvm.conf(5) lvmconfig(8)
