The PV may already be in a VG and may have ac- tive LVs allocated on it. USAGE pvresize PV ... [ --setphysicalvolumesize Size[m|UNIT] ] [ --reportformat basic|json ] [ COMMON_OPTIONS ] Common options for lvm: [ -d|--debug ] [ -h|--help ] [ -q|--quiet ] [ -t|--test ] [ -v|--verbose ] [ -y|--yes ] [ --commandprofile String ] [ --config String ] [ --driverloaded y|n ] [ --lockopt String ] [ --longhelp ] [ --nolocking ] [ --profile String ] [ --version ] OPTIONS --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 set- tings. 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|n If set to no, the command will not attempt to use device-mapper. For testing and debugging. -h|--help Display help text. --lockopt String Used to pass options for special cases to lvmlockd. See lvm- lockd(8) for more information. --longhelp Display long help text. --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 --ver- bose. 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. 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 un- usual 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 de- tail 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.) VARIABLES 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 ex- tents (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 con- tent. Size[UNIT] Size is an input number that accepts an optional unit. Input units are always treated as base two values, regardless of capi- talization, e.g. 'k' and 'K' both refer to 1024. The default input unit is specified by letter, followed by |UNIT. UNIT rep- resents 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.) ENVIRONMENT VARIABLES 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. NOTES pvresize will refuse to shrink a PV if it has allocated extents beyond the new end. EXAMPLES 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 SEE ALSO lvm(8) lvm.conf(5) lvmconfig(8) pvchange(8) pvck(8) pvcreate(8) pvdisplay(8) pvmove(8) pvremove(8) pvresize(8) pvs(8) pvscan(8) vgcfgbackup(8) vgcfgrestore(8) vgchange(8) vgck(8) vgcreate(8) vgcon- vert(8) vgdisplay(8) vgexport(8) vgextend(8) vgimport(8) vgimport- clone(8) vgmerge(8) vgmknodes(8) vgreduce(8) vgremove(8) vgrename(8) vgs(8) vgscan(8) vgsplit(8) lvcreate(8) lvchange(8) lvconvert(8) lvdisplay(8) lvextend(8) lvre- duce(8) lvremove(8) lvrename(8) lvresize(8) lvs(8) lvscan(8) lvm-fullreport(8) lvm-lvpoll(8) lvm2-activation-generator(8) blkdeacti- vate(8) lvmdump(8) dmeventd(8) lvmpolld(8) lvmlockd(8) lvmlockctl(8) cmirrord(8) lvmd- busd(8) lvmsystemid(7) lvmreport(7) lvmraid(7) lvmthin(7) lvmcache(7) Red Hat, Inc.
