PVCHANGE(8)                                                        PVCHANGE(8)



NAME
       pvchange - change attributes of a physical volume

SYNOPSIS
       pvchange  [-A|--autobackup  {y|n}]  [-d|--debug] [-h|--help] [-v|--ver-
       bose] [-a|--all] [-x|--allocation {y|n}] [PhysicalVolumePath...]

DESCRIPTION
       pvchange allows you to change the allocation permissions of one or more
       physical volumes.

   OPTIONS
       -A, --autobackup y/n
              Controls  automatic backup of VG metadata after the change ( 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.

       -v, --verbose
              Gives verbose runtime information about pvchange's activities.

       -a, --all
              If  PhysicalVolumePath  is not specified on the command line all
              physical volumes are searched for and used.

       -x, --allocation y/n
              Enable or disable allocation of physical extents on this  physi-
              cal volume.

Example
       "pvchange  -x n /dev/sdk1" disallows the allocation of physical extents
       on this physical volume (possibly because of disk errors, or because it
       will be removed after freeing it.

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

       1  no physical volume name(s) on command line
       2  no physical volume names found
       3  error changing physical volume in kernel
       4  error writing physical volume

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

       LVM_VG_MAX_BACKUPS
              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).
