  16 .SH DESCRIPTION
  17 vgreduce allows you to remove one or more unused physical volumes
  18 from a volume group.
  19 .SH OPTIONS
  20 See \fBlvm\fP(8) for common options.
  21 .TP
  22 .BR \-a ", " \-\-all
  23 Removes all empty physical volumes if none are given on command line.
  24 .TP
  25 .B \-\-removemissing
  26 Removes all missing physical volumes from the volume group, if there are no
  27 logical volumes allocated on those. This resumes normal operation of the volume
  28 group (new logical volumes may again be created, changed and so on).
  29
  30 If this is not possible (there are logical volumes referencing the missing
  31 physical volumes) and you cannot or do not want to remove them manually, you
  32 can run this option with \fB--force\fP to have \fBvgreduce\fP
  33 remove any partial LVs.
  34
  35 Any logical volumes and dependent snapshots that were partly on the
  36 missing disks get removed completely. This includes those parts
  37 that lie on disks that are still present.
  38
  39 If your logical volumes spanned several disks including the ones that are
  40 lost, you might want to try to salvage data first by activating your
  41 logical volumes with \fB--partial\fP as described in \fBlvm\fP(8).
