NAME
vgreduce - reduce a volume group
SYNOPSIS
vgreduce [-a|--all] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help]
[--removemissing] [-t|--test] [-v|--verbose] VolumeGroupName
[PhysicalVolumePath...]
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).
