NAME
vgsplit - split a volume group into two
SYNOPSIS
vgsplit [--alloc AllocationPolicy] [-A|--autobackup {y|n}]
[-c|--clustered {y|n}] [-d|--debug] [-h|--help] [-l|--maxlogicalvolumes
MaxLogicalVolumes] [-M|--metadatatype type] [-p|--maxphysicalvolumes
MaxPhysicalVolumes] [-n|--name LogicalVolumeName] [-t|--test]
[-v|--verbose] SourceVolumeGroupName DestinationVolumeGroupName [
PhysicalVolumePath ...]
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, and --maxphysicalvolumes (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.
OPTIONS
See lvm for common options.
