| .SH DESCRIPTION |
| vgreduce allows you to remove one or more unused physical volumes |
| from a volume group. |
| .SH OPTIONS |
| See \fBlvm\fP(8) for common options. |
| .TP |
| .BR \-a ", " \-\-all |
| Removes all empty physical volumes if none are given on command line. |
| .TP |
| .B \-\-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 \fB\-\-force\fP to have \fBvgreduce\fP |
| 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 \fB\-\-partial\fP as described in \fBlvm\fP(8). |
