NAME         top

       vgreduce — reduce a volume group

SYNOPSIS         top

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

DESCRIPTION         top

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

OPTIONS         top

       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 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).
