VGEXTEND(8)                 System Manager's Manual                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 avail-
       able for LVs in the VG.
       Also, PVs that have gone missing and then returned, e.g. due to a tran-
       sient device failure, can be added back to the VG without re-initializ-
       ing them (see --restoremissing).
       If the specified PVs have not yet been initialized with pvcreate, vgex-
       tend  will  initialize them. In this case pvcreate options can be used,
       e.g.  --labelsector,  --metadatasize,  --metadataignore,  --pvmetadata-
       copies, --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(5) set-
              tings.   The  String arg uses the same format as lvm.conf(5), or
              may use section/field syntax.  See lvm.conf(5) for more informa-
              tion about config.
       --dataalignment Size[k|UNIT]
              Align  the  start of a PV data area with a multiple of this num-
              ber.  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)  com-
              mand.   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.   out-
              put: record the default command output.  debug: record full com-
              mand 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 lvm-
              lockd(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.
       --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.
       --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 limi-
              tations on the ability to use vgsplit later.)
       -q|--quiet ...
              Suppress output and log messages. Overrides --debug  and  --ver-
              bose.   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(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. 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  reini-
              tialized.
       -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 con-
              tent.
       Size[UNIT]
              Size is an input number that accepts an  optional  unit.   Input
              units are always treated as base two values, regardless of capi-
              talization, e.g. 'k' and 'K' both refer to  1024.   The  default
              input unit is specified by letter, followed by |UNIT.  UNIT rep-
              resents 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
       Add two PVs to a VG.
       vgextend vg00 /dev/sda4 /dev/sdn1
