VGSPLIT(8)                                                          VGSPLIT(8)



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] [-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,   --meta-
       datatype,  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 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.

       See lvm for common options.
