VGSPLIT(8)                  System Manager's Manual                 VGSPLIT(8)



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 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.
