       vgextend - add physical volumes to a volume group

       vgextend [-A|--autobackup{y|n}] [-d|--debug] [-h|--help] [-v|--verbose]
       VolumeGroupName PhysicalVolumePath [PhysicalVolumePath...]

       vgextend allows you to add one or more initialized physical  volumes  (
       see pvcreate(8) ) to an existing volume group to extend it in size.

       -A, --autobackup y/n
              Controls  automatic backup of VG metadata after the change ( see
              vgcfgbackup(8) ). Default is yes.

       -d, --debug
              Enables additional debugging output (if compiled with DEBUG).

       -h, --help
              Print a usage message on standard output and exit  successfully.

       -v, --verbose
              Gives verbose runtime information about lvextend's activities.

       "vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing volume
       group "vg00" by the new physical volumes (see pvcreate(8) ) "/dev/sdn1"
       and /dev/sda4".

       vgextend returns an exit code of 0 for success and > 0 for error:

       1  no volume group name on command line
       2  volume group name not given as first argument
       3  no physical volume(s) on command line
       4  invalid volume group name
       5  error checking existence of volume group
       6  inactive volume group
       7  error reading VGDA
       8  volume group is set to not extendable
       9  maximum physical volume number of volume group exceeded
       10 error reading all physical volumes
       11 error setting up VGDA
       12 error extending VGDA in kernel
       13 error writing VGDA to physical volume(s)

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line

              If  this variable is set to "no" then the automatic backup of VG
              metadata is turned off.

              This variable determines the backup history depth of  kept  VGDA
              copy  files  in /etc/lvmconf. It can be set to a positive number
              between 0 and 999.  The higher this number is, the more  changes
              you can restore using vgcfgrestore(8).
