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).
