.SH DESCRIPTION
|
|
.B vgchange
|
|
allows you to change the attributes of one or more volume groups.
|
|
Its main purpose is to activate and deactivate
|
|
.IR VolumeGroupName ,
|
|
or all volume groups if none is specified. Only active volume groups
|
|
are subject to changes and allow access to their logical volumes.
|
|
During volume group activation, if
|
|
.B vgchange
|
|
recognizes snapshot logical volumes which were dropped because they ran
|
|
out of space, it displays a message informing the administrator that such
|
|
snapshots should be removed (see
|
|
.BR lvremove (8)).
|
|

See \fBlvm\fP for common options.

.TP
