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

     NAME
          vgextend - Add physical volumes to a volume group

     SYNOPSIS
          vgextend position_args
              [ option_args ]

     DESCRIPTION
          vgextend adds one or more PVs to a VG. This increases the
          space available for LVs in the VG.

          Also, PVs that have gone missing and then returned, e.g. due
          to a transient device failure, can be added back to the VG
          without re-initializing them (see --restoremissing).

          If the specified PVs have not yet been initialized with
          pvcreate, vgextend will initialize them. In this case
          pvcreate options can be used, e.g.  --labelsector,
          --metadatasize, --metadataignore, --pvmetadatacopies,
          --dataalignment, --dataalignmentoffset.

              [    --profile String ]
              [    --version ]

     OPTIONS
          -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.

          --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).

          --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.

          --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

     Page 2                    Red Hat, Inc.         (printed 5/25/22)

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

               source). Use with care.

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

          --longhelp
               Display long help text.

          --metadataignore y|n
               Specifies the metadataignore property of a PV.  If yes,
               metadata areas on the PV are ignored, and lvm will not
               store metadata in the metadata areas of the PV.  If no,
               lvm will store metadata on the PV.

          --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.

          --nolocking
               Disable locking.

          --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
               Overrides current output format for reports which is
               defined globally by the report/output_format setting in
               lvm.conf.  basic is the original format with columns
               and rows.  If there is more than one report per

     Page 3                    Red Hat, Inc.         (printed 5/25/22)

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

               command, each report is prefixed with the report name
               for identification. json produces report output in JSON
               format. See lvmreport(7) for more information.

          --restoremissing
               Add a PV back into a VG after the PV was missing and
               then returned, e.g. due to a transient failure. The PV
               is not reinitialized.

          -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.

          -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: bBsSkKmMgGtTpPeE.  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
          Add two PVs to a VG.
          vgextend vg00 /dev/sda4 /dev/sdn1
