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


Usage:

Command Line Options:

--commandprofile
The command profile to use for command configuration. See lvm.conf(5) for more information about pro‐files.
pvresize --commandprofile ...
--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.
pvresize --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).
pvresize -d|--debug ...
--driverloaded
If set to no, the command will not attempt to use device-mapper. For testing and debugging.
pvresize --driverloaded ...
-h|--help

pvresize -h|--help ...
--longhelp
Display long help text.
pvresize --longhelp ...
--profile

pvresize -q|--quiet ...
--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.
pvresize --reportformat ...
--setphysicalvolumesize
Overrides the automatically detected size of the PV. Use with care, or prior to reducing the physicalsize of the device.
pvresize --setphysicalvolumesize ...
-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.
pvresize -t|--test ...
-v|--verbose
Set verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout andstderr.
pvresize -v|--verbose ...
--version
Display version information.
pvresize --version ...
-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
