vgreduce allows you to remove one or more unused physical volumes from
a volume group.
See lvm for common options.
Removes all empty physical volumes if none are given on command
Removes all missing physical volumes from the volume group and
makes the volume group consistent again.
It's a good idea to run this option with --test first to find
out what it would remove before running it for real.
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
