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.

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 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 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
