NAME

       pvresize - Resize physical volume(s)

SYNOPSIS

       pvresize position_args
           [ option_args ]

DESCRIPTION

       pvresize  resizes a PV. The PV may already be in a VG and may have active 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 ]
           [    --longhelp ]
           [    --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 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.

       --longhelp
              Display long help text.

       --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

       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

       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
