vgreduce − reduce a volume group
vgreduce [−a|−−all] [−A|−−autobackup{y|n}] [−d|−−debug] [−h|−−help] [−v|−−verbose] VolumeGroupName [PhysicalVolumePath...]
vgreduce allows you to remove one or more unused physical volumes from a volume group.
OPTIONS
−a, −−all
Removes all empty physical volumes if none are given on command line.
−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 vgreduce’s activities.
vgreduce returns an exit code of 0 for success and > 0 for error:
1 neither
volume group name nor physical volume path(s) on command
line
2 invalid volume group name
3 error checking existence of volume group
4 volume group must be active
5 error reading VGDA

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).
