NAME

       pvchange - change attributes of a physical volume

SYNOPSIS

       pvchange     [-A|--autobackup     {y|n}]    [-d|--debug]    [-h|--help]
       [-v|--verbose]        [-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 pvchangeā€™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
              physical 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).
