VGSPLIT(8)     (LVM TOOLS 2.03.11(2) (2021-01-08))     VGSPLIT(8)

     NAME
          vgsplit - Move physical volumes into a new or existing
          volume group

     SYNOPSIS
          vgsplit option_args position_args
              [ option_args ]

     DESCRIPTION
          vgsplit moves one or more PVs from a source VG (the first VG
          arg) to a destination VG (the second VG arg).  The PV(s) to
          move are named after the source and destination VGs, or an
          LV is named, in which case the PVs underlying the LV are
          moved.

          If the destination VG does not exist, a new VG is created
          (command options can be used to specify properties of the
          new VG, also see vgcreate(8).)

          LVs cannot be split between VGs; each LV must be entirely on
          the PVs in the source or destination VG.

          vgsplit can only move complete PVs. (See pvmove(8) for
          moving part of a PV.)

          Split a VG by specified PVs.

     OPTIONS
          --alloc
               contiguous|cling|cling_by_tags|normal|anywhere|inherit
               Determines the allocation policy when a command needs
               to allocate Physical Extents (PEs) from the VG. Each VG
               and LV has an allocation policy which can be changed
               with vgchange/lvchange, or overriden on the command
               line.  normal applies common sense rules such as not
               placing parallel stripes on the same PV.  inherit
               applies the VG policy to an LV.  contiguous requires
               new PEs be placed adjacent to existing PEs.  cling
               places new PEs on the same PV as existing PEs in the
               same stripe of the LV.  If there are sufficient PEs for
               an allocation, but normal does not use them, anywhere
               will use them even if it reduces performance, e.g. by
               placing two stripes on the same PV.  Optional
               positional PV args on the command line can also be used
               to limit which PVs the command will use for allocation.
               See lvm(8) for more information about allocation.

          -A|--autobackup y|n
               Specifies if metadata should be backed up automatically
               after a change.  Enabling this is strongly advised! See
               vgcfgbackup(8) for more information.

          --commandprofile String
               The command profile to use for command configuration.
               See lvm.conf(5) for more information about profiles.

          --config String
               Config settings for the command. These override
               lvm.conf settings.  The String arg uses the same format
               as lvm.conf, or may use section/field syntax.  See
               lvm.conf(5) for more information about config.

          -d|--debug ...
               Set debug level. Repeat from 1 to 6 times to increase
               the detail of messages sent to the log file and/or
               syslog (if configured).

          --driverloaded y|n

     VGSPLIT(8)     (LVM TOOLS 2.03.11(2) (2021-01-08))     VGSPLIT(8)

               If set to no, the command will not attempt to use
               device-mapper.  For testing and debugging.

          -h|--help
               Display help text.

          --lockopt String
               Used to pass options for special cases to lvmlockd.
               See lvmlockd(8) for more information.

          --longhelp
               Display long help text.

          -l|--maxlogicalvolumes Number
               Sets the maximum number of LVs allowed in a VG.

          -p|--maxphysicalvolumes Number
               Sets the maximum number of PVs that can belong to the
               VG.  The value 0 removes any limitation.  For large
               numbers of PVs, also see options --pvmetadatacopies,
               and --vgmetadatacopies for improving performance.

          -M|--metadatatype lvm2
               Specifies the type of on-disk metadata to use.  lvm2
               (or just 2) is the current, standard format.  lvm1 (or
               just 1) is no longer used.

          -n|--name String
               Move only PVs used by the named LV.

          --nolocking
               Disable locking.

          --profile String
               An alias for --commandprofile or --metadataprofile,
               depending on the command.

          -q|--quiet ...
               Suppress output and log messages. Overrides --debug and
               --verbose.  Repeat once to also suppress any prompts
               with answer 'no'.

          -t|--test
               Run in test mode. Commands will not update metadata.
               This is implemented by disabling all metadata writing
               but nevertheless returning success to the calling
               function. This may lead to unusual error messages in
               multi-stage operations if a tool relies on reading back
               metadata it believes has changed but hasn't.

          -v|--verbose ...
               Set verbose level. Repeat from 1 to 4 times to increase

     VGSPLIT(8)     (LVM TOOLS 2.03.11(2) (2021-01-08))     VGSPLIT(8)

               the detail of messages sent to stdout and stderr.

          --version
               Display version information.

          --[vg]metadatacopies all|unmanaged|Number
               Number of copies of the VG metadata that are kept.  VG
               metadata is kept in VG metadata areas on PVs in the VG,
               i.e. reserved space at the start and/or end of the PVs.
               Keeping a copy of the VG metadata on every PV can
               reduce performance in VGs containing a large number of
               PVs.  When this number is set to a non-zero value, LVM
               will automatically choose PVs on which to store
               metadata, using the metadataignore flags on PVs to
               achieve the specified number.  The number can also be
               replaced with special string values: unmanaged causes
               LVM to not automatically manage the PV metadataignore
               flags.  all causes LVM to first clear the
               metadataignore flags on all PVs, and then to become
               unmanaged.

          -y|--yes
               Do not prompt for confirmation interactively but always
               assume the answer yes. Use with extreme caution.  (For
               automatic no, see -qq.)

     VARIABLES
          VG
               Volume Group name.  See lvm(8) for valid names.

          PV
               Physical Volume name, a device path  under  /dev.   For
               commands managing physical extents, a PV positional arg
               generally accepts  a  suffix  indicating  a  range  (or
               multiple  ranges)  of  physical extents (PEs). When the
               first PE is omitted, it defaults to the  start  of  the
               device,  and when the last PE is omitted it defaults to
               end.  Start and end  range  (inclusive):  PV[:PE-PE]...
               Start and length range (counting from 0): PV[:PE+PE]...

          String
               See the option description for  information  about  the
               string content.

          Size[UNIT]
               Size is an input number that accepts an optional  unit.
               Input  units  are  always  treated  as base two values,
               regardless of capitalization, e.g.  'k'  and  'K'  both
               refer  to 1024.  The default input unit is specified by
               letter,  followed  by  |UNIT.   UNIT  represents  other
               possible  input units: bBsSkKmMgGtTpPeE.  b|B is bytes,
               s|S is sectors of 512 bytes, k|K is KiB,  m|M  is  MiB,

     VGSPLIT(8)     (LVM TOOLS 2.03.11(2) (2021-01-08))     VGSPLIT(8)

               g|G  is GiB, t|T is TiB, p|P is PiB, e|E is EiB.  (This
               should not be confused with the output control --units,
               where capital letters mean multiple of 1000.)

     ENVIRONMENT VARIABLES
          See lvm(8) for information about environment variables  used
          by   lvm.    For   example,  LVM_VG_NAME  can  generally  be
          substituted for a required VG parameter.
