NAME         top

       pvresize - Resize physical volume(s)

SYNOPSIS         top

       pvresize position_args
           [ option_args ]

DESCRIPTION         top

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

OPTIONS         top

       --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
              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|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
              lvmlockd(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
              --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.  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.)

VARIABLES         top

       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: 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         top

       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         top

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

EXAMPLES         top

       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
