VGREDUCE(8)                                                        VGREDUCE(8)




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
              activating  your  logical volumes with --partial as described in
              lvm (8).
