NAME
       vgreduce -- reduce a volume group

SYNOPSIS
       vgreduce	 [-a|--all] [-A|--autobackup {y|n}] [--commandprofile Profile-
       Name]  [-d|--debug]  [-h|-?|--help]  [--removemissing]  [--reportformat
       {basic|json}]  [-t|--test] [-v|--verbose] VolumeGroupName [PhysicalVol-
       umePath...]

DESCRIPTION
       vgreduce allows you to remove one or more unused physical volumes  from
       a volume group.

OPTIONS
       See lvm(8) for common options.

       -a, --all
	      Removes  all empty physical volumes if none are given on command
	      line.

       --removemissing
	      Removes all missing physical volumes from the volume  group,  if
	      there  are  no  logical volumes allocated on those. This resumes
	      normal operation of the volume group (new	 logical  volumes  may
	      again be created, changed and so on).

	      If  this	is not possible (there are logical volumes referencing
	      the missing physical volumes) and you cannot or do not  want  to
	      remove  them  manually,  you can run this option with --force to
	      have vgreduce remove any partial LVs.

	      Any logical volumes and dependent snapshots that were partly  on
	      the  missing  disks  get removed completely. This includes those
	      parts that lie on disks that are still present.

	      If your logical volumes spanned several disks including the ones
	      that  are	 lost,	you might want to try to salvage data first by
	      activating your logical volumes with --partial as	 described  in
	      lvm(8).
