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 MaxLogi-
       calVolumes] [-M|--metadatatype  type]  [-p|--maxphysicalvolumes  MaxPhysicalVolumes]  [--[vg]metadatacopies]  NumberOfCopies|unmanaged|all]
       [-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, --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 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.

       A vgsplit into an existing volume group retains the existing volume group's value of vgmetadatacopies (see vgcreate and lvm.conf  for  fur-
       ther explanation of vgmetadatacopies).  To change the value of vgmetadatacopies, use vgchange.

OPTIONS

       See lvm for common options.
