NAME

       vgreduce - reduce a volume group

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

       See lvm 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 acti-
              vating your logical volumes with --partial as described in lvm (8).
