NAME

       pvresize - resize a physical volume in a volume group

SYNOPSIS

       pvresize     [-A|--autobackup     {y|n}]    [-d|--debug]    [-h|--help]
       [-s|--sizePhysicalVolumeSize[kKmMgGtT]]   [-v|--verbose]    [--version]
       PhysicalVolume [PhysicalVolume...]

DESCRIPTION

       pvresize  allows  you  to  change  the  size of a physical volume which
       belongs to a volume group in case the underlying device  changes  size.
       Examples  are  hardware  RAID systems which allow resizing without data
       loss or size changes  on  loop  devices.   The  volume  group  must  be
       inactive to run this command.

   OPTIONS
       -A, --autobackup y/n
              Controls  automatic backup of VG metadata after the resize ( see
              vgcfgbackup(8) ). Default is yes.

       -d, --debug
              Enables additional debugging output (if compiled with DEBUG).

       -h, --help
              Print a usage message on standard output and exit  successfully.

       -s, --size
              Overrides  the  size  of  the  physical volume which is normally
              retrieved.  Useful in rare case where this value is wrong.  More
              useful  to  fake  large physical volumes of up to 2 Terabyes - 1
              Kilobyte on smaller devices for testing purposes only  where  no
              real  access  to  data in created logical volumes is needed.  If
              you wish to create  the  supported  maximum,  use  "pvcreate  -s
              2147483647k PhysicalVolume [PhysicalVolume ...]".  All other LVM
              tools will use this size with the exception of lvmdiskscan(8)

       -v, --verbose
              Gives verbose runtime information about pvresize’s activities.

       Example
              "pvresize /dev/sdk1" resizes physical volume in /dev/sdk1 to the
              size the operating system reports.

DIAGNOSTICS

       pvresize returns an exit code of 0 for success and > 0 for error:

       1  no physical volume name(s) on command line
       2  invalid physical volume name
       3  error writing VGDA to physical volumes
       4  error doing backup of VGDA to disk
       5  error storing VGDA in lvmtab

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line

ENVIRONMENT VARIABLES

       LVM_AUTOARCHIVE
              If  this variable is set to "no" then the automatic backup of VG
              metadata is turned off.

       LVM_MAX_ARCHIVES
              This variable determines the backup history depth of  kept  VGDA
              copy  files  in /etc/lvmconf. It can be set to a positive number
              between 0 and 999.  The higher this number is, the more  changes
              you can restore using vgcfgrestore(8).
