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

       vgsplit — split a volume group into two

       vgsplit  [--alloc AllocationPolicy] [-A|--autobackup {y|n}] [-c|--clustered {y|n}] [--com‐
       mandprofile ProfileName] [-d|--debug] [-h|--help]  [-l|--maxlogicalvolumes  MaxLogicalVol‐
       umes]  [-M|--metadatatype  type] [-p|--maxphysicalvolumes MaxPhysicalVolumes] [--[vg]meta‐
       datacopies   NumberOfCopies|unmanaged|all]   [-n|--name   LogicalVolumeName]   [-t|--test]
       [-v|--verbose] SourceVolumeGroupName DestinationVolumeGroupName [PhysicalVolumePath...]

       vgsplit moves one or more physical volumes from SourceVolumeGroupName into DestinationVol‐
       umeGroupName.  The physical volumes moved can be specified either  explicitly  via  Physi‐
       calVolumePath,  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

       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 destina‐
       tion 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  vgmetadata‐
       copies).  To change the value of vgmetadatacopies, use vgchange(8).

       See lvm(8) for common options.
