pvresize — Resize physical volume(s)

pvresize position_args
[ option_args ]

pvresize resizes a PV. The PV may already be in a VG and may have active LVs allocated on it.

[ COMMON_OPTIONS ]

Common options for lvm:

[ -d*|–debug* ]
[ -h*|–help* ]
[ -q*|–quiet* ]
[ -t*|–test* ]
[ -v*|–verbose* ]
[ -y*|–yes* ]
[ –commandprofile String ]
[ –config String ]
[ –devices PV ]
[ –devicesfile String ]
[ –driverloaded y*|*n ]
[ –journal String ]
[ –lockopt String ]
[ –longhelp ]
[ –nohints ]
[ –nolocking ]
[ –profile String ]
[ –version ]

–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
Devices that the command can use. 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.

-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.

–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.

–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.

–setphysicalvolumesize Size[m|UNIT]
Overrides the automatically detected size of the PV. Use with care, or prior to reducing the physical size of the device.

-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.

-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.)

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/]…

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.)

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.

pvresize will refuse to shrink a PV if it has allocated extents beyond the new end.

Expand a PV after enlarging the partition.
pvresize /dev/sda1

Shrink a PV prior to shrinking the partition (ensure that the PV size is appropriate for the intended new partition size).
pvresize –setphysicalvolumesize 40G /dev/sda1
