DESCRIPTION¶
vgsplit moves one or more physical volumes from
SourceVolumeGroupName into
DestinationVolumeGroupName. The
physical volumes moved can be specified either explicitly via
PhysicalVolumePath, or implicitly by -n
LogicalVolumeName, in which case only physical volumes
underlying the specified logical volume will be moved.
If
DestinationVolumeGroupName does not exist, a new volume group will be
created. The default attributes for the new volume group can be specified with
--alloc,
--clustered,
--maxlogicalvolumes,
--metadatatype,
--maxphysicalvolumes and
--[vg]metadatacopies, (see
vgcreate(8) for a description of
these options). If any of these options are not given, default attribute(s)
are taken from
SourceVolumeGroupName. If a non-LVM2 metadata type (e.g.
lvm1) is being used, you should use the -M option to specify the
metadata type directly.
If
DestinationVolumeGroupName does exist, it will be checked for
compatibility with
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.
Vgsplit(8) only
moves complete physical volumes: To move part of a physical volume, use
pvmove(8). Each existing logical volume must be entirely on the
physical volumes forming either the source or the destination volume group.
For this reason,
vgsplit(8) may fail with an error if a split would
result in a logical volume being split across volume groups.
A
vgsplit into an existing volume group retains the existing volume
group's value of
vgmetadatacopies (see
vgcreate and
lvm.conf for further explanation of
vgmetadatacopies). To change
the value of
vgmetadatacopies, use
vgchange.
OPTIONS¶
See
lvm for common options.
