NAME
vgsplit - split a volume group into two
SYNOPSIS
vgsplit [--alloc AllocationPolicy] [-A|--autobackup {y|n}] [-c|--clus-
tered {y|n}] [-d|--debug] [-h|--help] [-l|--maxlogicalvolumes MaxLogi-
calVolumes] [-M|--metadatatype type] [-p|--maxphysicalvolumes MaxPhysi-
calVolumes] [--[vg]metadatacopies NumberOfCopies|unmanaged|all]
[-n|--name LogicalVolumeName] [-t|--test] [-v|--verbose] SourceVol-
umeGroupName 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, --meta-
datatype, --maxphysicalvolumes and --[vg]metadatacopies (see vgcre-
ate(8) for a description of these options). If any of these options
are not given, default attribute(s) are taken from SourceVolumeGroup-
Name. 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 com-
patibility 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 physi-
cal 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(8) and lvm.conf(5) for
further explanation of vgmetadatacopies). To change the value of
vgmetadatacopies, use vgchange(8).
OPTIONS
See lvm(8) for common options.
