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 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 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).
