       vgreduce - reduce a volume group


       vgreduce  [-a|--all]  [-A|--autobackup  y|n] [-d|--debug] [-h|-?|--help] [--removemissing]
       [-t|--test] [-v|--verbose] VolumeGroupName [PhysicalVolumePath...]


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


       See lvm 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).
