--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).

--driverloaded

If set to no, the command will not attempt to use device-mapper. For testing and debugging.

-h|--help

Display help text.

--labelsector

By default the PV is labelled with an LVM2 identifier in its second sector (sector 1). This lets youuse a different sector near the start of the disk (between 0 and 3 inclusive - see LABEL_SCAN_SECTORSin the source). Use with care.

--longhelp

Display long help text.

--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'.

-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.

-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]...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

For example, LVM_VG_NAME can generally besubstituted for a required VG parameter.EXAMPLESIf the partition table is corrupted or lost on /dev/sda, and you suspect there was an LVM partition at approx‐imately 100 MiB, then this area of the disk can be scanned using the --labelsector parameter with a value of204800 (100 * 1024 * 1024 / 512 = 204800).pvck --labelsector 204800 /dev/sda
