NAME

       lvmpvg - LVM physical volume group information file

SYNOPSIS

DESCRIPTION

       is  an  ASCII file that stores the volume-group information for all of the physical volume groups in the system.  The information is stored
       in a hierarchical format.

       First, it starts with a volume group under which multiple physical volume groups can exist.  Under each physical volume group,  a  list	of
       physical  volumes  can be specified.  There must be at least one physical volume group in each volume group that appears in this file.  The
       physical-volume-group name must be unique within the corresponding volume group, although it is permissible to use a common physical volume
       group name across different volume groups.  There can be as many volume groups in this file as there are in the system.

       Instead of using the and commands, the administrator can edit this file to create and extend physical volume groups.  However, care must be
       taken to ensure that all physical volumes to be included in the file have already been defined in their respective volume groups by  previ-
       ous use of or

       The  file  format  has  the  following structure.  and are keywords that introduce the names of the volume group and physical volume group,
       respectively.

	      pv_path
		 ...
	      pv_path
		 ...
	      pv_path
		 ...

       The variables are defined as follows:

	      pv_path	     The block device path name of a physical volume within the volume group.

	      pvg_name	     The name of the physical volume group.  It must be unique within the volume group.

	      vg_name	     The path name of the volume group.

EXAMPLES

       The following example shows an file containing two volume groups: the first containing two physical volume groups, each with  two  physical
       volumes defined in it; the second containing three physical volume groups, each with one physical volume defined in it.

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.
