       vgreduce — reduce a volume group


       vgreduce  [-a|--all]  [-A|--autobackup  {y|n}] [--commandprofile ProfileName] [-d|--debug]
       [-h|-?|--help]    [--removemissing]     [-t|--test]     [-v|--verbose]     VolumeGroupName


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


       See lvm(8) for common options.

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

              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

              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).
