NAME

       vgcreate — Create a volume group

SYNOPSIS

       vgcreate position_args
           [ option_args ]

DESCRIPTION

       vgcreate creates a new VG on block devices. If the devices were not previously initialized
       as PVs with pvcreate(8), vgcreate will inititialize them, making them  PVs.  The  pvcreate
       options for initializing devices are also available with vgcreate.

       When  vgcreate uses an existing PV, that PV's existing values for metadata size, PE start,
       etc, are used, even if different values are specified in the vgcreate command.  To  change
       these values, first use pvremove on the device.

OPTIONS

       --addtag Tag
              Adds  a  tag to a PV, VG or LV. This option can be repeated to add multiple tags at
              once. See lvm(8) for information about tags.

       --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.

       -c|--clustered y|n
              This  option  was  specific to clvm and is now replaced by the --shared option with
              lvmlockd(8).

       --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.

       --dataalignment Size[k|UNIT]
              Align  the  start  of  a  PV  data area with a multiple of this number.  To see the
              location of the first Physical Extent (PE) of an existing PV, use pvs -o +pe_start.
              In  addition,  it may be shifted by an alignment offset, see --dataalignmentoffset.
              Also specify an appropriate PE size when creating a VG.

       --dataalignmentoffset Size[k|UNIT]
              Shift the start of the PV data area by this additional offset.

       -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.

       -f|--force ...
              Override various checks, confirmations and protections.  Use with extreme caution.

       -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.

       --labelsector Number
              By  default the PV is labelled with an LVM2 identifier in its second sector (sector
              1). This lets you use a different sector near the start of the disk (between 0  and
              3 inclusive - see LABEL_SCAN_SECTORS in the source). Use with care.

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

       --locktype sanlock|dlm|none
              Specify the VG lock type directly in place of using --shared.  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.

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

       --metadatasize Size[m|UNIT]
              The approximate amount of space used for each VG metadata area.  The  size  may  be
              rounded.

       -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.

       --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.

       -s|--physicalextentsize Size[m|UNIT]
              Sets  the  physical extent size of PVs in the VG.  The value must be either a power
              of 2 of at least 1 sector (where the sector size is the largest sector size of  the
              PVs  currently used in the VG), or at least 128 KiB.  Once this value has been set,
              it is difficult to change without recreating the VG, unless no extents need moving.

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

       --pvmetadatacopies 0|1|2
              The number of metadata areas to set aside on a PV for storing VG metadata.  When 2,
              one  copy  of the VG metadata is stored at the front of the PV and a second copy is
              stored at the end.  When 1, one copy of the VG metadata is stored at the  front  of
              the PV.  When 0, no copies of the VG metadata are stored on the given PV.  This may
              be useful in VGs containing many PVs (this places limitations on the ability to use
              vgsplit later.)

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

       --reportformat basic|json|json_std
              Overrides current output format for  reports  which  is  defined  globally  by  the
              report/output_format  setting  in  lvm.conf(5).   basic is the original format with
              columns and rows.  If there is more than one report per  command,  each  report  is
              prefixed  with  the  report name for identification. json produces report output in
              JSON format. json_std produces report output in JSON format which is more compliant
              with JSON standard.  See lvmreport(7) for more information.

       --setautoactivation y|n
              Set  the  autoactivation  property on a VG or LV.  Display the property with vgs or
              lvs "-o autoactivation".  When the autoactivation property is disabled, the  VG  or
              LV  will not be activated by a command doing autoactivation (vgchange, lvchange, or
              pvscan using -aay.)  If autoactivation  is  disabled  on  a  VG,  no  LVs  will  be
              autoactivated  in  that  VG,  and the LV autoactivation property has no effect.  If
              autoactivation is enabled on a VG, autoactivation can be  disabled  for  individual
              LVs.

       --shared
              Create  a shared VG using lvmlockd if LVM is compiled with lockd support.  lvmlockd
              will select lock type sanlock or dlm depending on which lock  manager  is  running.
              This  allows  multiple  hosts  to share a VG on shared devices. lvmlockd and a lock
              manager must be configured and running.  See lvmlockd(8) for more information about
              shared VGs.

       --systemid String
              Specifies  the system ID that will be given to the new VG, overriding the system ID
              of the host running the command. A VG is normally created without this  option,  in
              which  case  the  new VG is given the system ID of the host creating it. Using this
              option requires caution because the system ID of the  new  VG  may  not  match  the
              system ID of the host running the command, leaving the VG inaccessible to the host.
              See lvmsystemid(7) for more information.

       -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.)

       -Z|--zero y|n
              Controls  if the first 4 sectors (2048 bytes) of the device are wiped.  The default
              is to wipe these sectors unless either or  both  of  --restorefile  or  --uuid  are
              specified.

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.

EXAMPLES

       Create a VG with two PVs, using the default physical extent size.
       vgcreate myvg /dev/sdk1 /dev/sdl1
