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.)

USAGE

       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 overridden 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(5) settings.  The String
              arg uses the same format as lvm.conf(5), 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).

       --devices PV
              Restricts the devices that are visible and accessible to the command.  Devices  not
              listed  will  appear to be missing. This option can be repeated, or accepts a comma
              separated list of devices. This overrides the devices file.

       --devicesfile String
              A  file  listing  devices  that  LVM  should  use.   The   file   must   exist   in
              /etc/lvm/devices/  and  is  managed with the lvmdevices(8) command.  This overrides
              the lvm.conf(5) devices/devicesfile and devices/use_devicesfile settings.

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

       -h|--help
              Display help text.

       --journal String
              Record  information  in  the  systemd  journal.  This information is in addition to
              information  enabled  by  the  lvm.conf  log/journal  setting.    command:   record
              information  about the command.  output: record the default command output.  debug:
              record full command debugging.

       --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.

       --nohints
              Do not use the hints file to locate devices  for  PVs.  A  command  may  read  more
              devices  to  find  PVs  when  hints  are  not  used. The command will still perform
              standard hint file invalidation where appropriate.

       --nolocking
              Disable locking. Use  with  caution,  concurrent  commands  may  produce  incorrect
              results.

       --poolmetadataspare y|n
              Enable or disable the automatic creation and management of a spare pool metadata LV
              in the VG. A spare metadata LV is reserved space that can be used when repairing  a
              pool.

       --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 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: b|B is bytes, s|S is sectors of 512
              bytes, k|K is KiB, m|M is MiB, 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.
