       vgreduce - reduce a volume group


       vgreduce  [-a/--all]  [-A/--autobackup y/n] [-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 for common options.

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

              Removes  all  missing physical volumes from the volume group and
              makes the volume group consistent again.

              It’s a good idea to run this option with --test  first  to  find
              out what it would remove before running it for real.

              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).
