|
|
.SH DESCRIPTION
|
|
vgreduce allows you to remove one or more unused physical volumes
|
|
from a volume group.
|
|
.SH OPTIONS
|
|
See \fBlvm\fP for common options.
|
|
.TP
|
|
.I \-a, \-\-all
|
|
Removes all empty physical volumes if none are given on command line.
|
|
.TP
|
|
.I \-\-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 \fBlvm (8)\fP.
