NAME

       gfs2_grow - Expand a GFS2 filesystem

SYNOPSIS

       gfs2_grow [OPTION]... <DEVICE|MOUNTPOINT>...

DESCRIPTION

       gfs2_grow expands a GFS2 filesystem after the device upon which the filesystem resides has
       also been expanded. gfs2_grow expands the GFS2 filesystem  to  utilize  any  unused  space
       between  the  current  end  of  the filesystem and the end of the block device.  When this
       operation is complete, the resource group index for the filesystem is updated so that  all
       nodes in the cluster can use the extra storage space that has been added.

       See  lvmlockd(8)  for  the  procedure  to  extend  and refresh the logical volume prior to
       running gfs2_grow.

       The DEVICE or MOUNTPOINT arguments must be paths  to  mounted  filesystems;  expansion  of
       unmounted  filesystems  is  not  supported.  gfs2_grow need only be run on one node in the
       cluster.  The other nodes will see the expansion has occurred and automatically  start  to
       use the newly available space.

       gfs2_grow  must  be  run  as  the  superuser. When the filesystem cannot be resized due to
       detected errors, gfs2_grow will leave the filesystem in a consistent state.

OPTIONS

       -D     Print out debugging information about the filesystem layout.

       -h     Prints out a short usage message and exits.

       -q     Be quiet.  Don't print anything.

       -T     Test. Do all calculations, but do not write any data to the disk and do not  expand
              the  filesystem. This is used to discover what the tool would have done were it run
              without this flag. This option can be used  to  display  the  current  state  of  a
              mounted GFS2 filesystem.

       -V     Version. Print out version information, then exit.

NOTES

       Shrinking GFS2 filesystems is currently unsupported.
