pvchange − change attributes of a physical volume
pvchange [−A|−−autobackup {y|n}] [−d|−−debug] [−h|−−help] [−v|−−verbose] [−a|−−all] [−x|−−allocation {y|n}] [PhysicalVolumePath...]
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.
"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.
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
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).
