.SH DESCRIPTION
|
|
.B vgsplit
|
|
moves
|
|
.IR PhysicalVolumePath (s)
|
|
from
|
|
.I SourceVolumeGroupName
|
|
into
|
|
.I DestinationVolumeGroupName\fP.
|
|
|
|
If
|
|
.I DestinationVolumeGroupName
|
|
does not exist, a new volume group will be created. The default attributes
|
|
for the new volume group can be specified with \fB\-\-alloc\fR,
|
|
\fB\-\-clustered\fR, \fB\-\-maxlogicalvolumes\fR, \fB\-\-metadatatype\fR,
|
|
and \fB\-\-maxphysicalvolumes\fR (see \fBvgcreate(8)\fR for a description
|
|
of these options). If any of these options are not given, default
|
|
attribute(s) are taken from
|
|
.I SourceVolumeGroupName\fP.
|
|
|
|
If
|
|
.I DestinationVolumeGroupName
|
|
does exist, it will be checked for compatibility with
|
|
.I SourceVolumeGroupName
|
|
before the physical volumes are moved. Specifying any of the above default
|
|
volume group attributes with an existing destination volume group is an error,
|
|
and no split will occur.
|
|
|
|
Logical Volumes cannot be split between Volume Groups.
|
|
Each existing Logical Volume must be entirely on the Physical Volumes forming
|
|
either the source or the destination Volume Group.
