 NAME
      extendfs (generic) - extend a file system size

 SYNOPSIS
      /usr/sbin/extendfs [-F FStype] [-q] [-v] [-s size] special

 DESCRIPTION
      If the original file system image created on special does not make use
      of all of the available space, extendfs can be used to increase the
      capacity of a file system by updating the file system structure to
      include the extra space.

      The command-line parameter special specifies the device special file
      of either a logical volume or a disk partition. The special must be
      un-mounted before extendfs can be run (see mount(1M)).

    Options
      extendfs recognizes the following options:

	   -F FStype Specify the file system type on which to operate (see
		     fstyp(1M) and fs_wrapper(5)).  If this option is not
		     included on the command line, then the file system type
		     is determined from the file /etc/default/fs.

	   -q	     Query the size of special.	 No file system extension
		     will be done.

	   -v	     Verbose flag.

	   -s size   Specifies the number of DEV_BSIZE blocks to be added to
		     the file system.  If  size is not specified, the
		     maximum possible size is used.

 EXAMPLES
      To increase the capacity of a file system created on a logical volume,
      enter:

	   umount /dev/vg00/lvol1

	   lvextend -L larger_size /dev/vg00/lvol1

	   extendfs -F hfs /dev/vg00/rlvol1

	   mount /dev/vg00/lvol1 mount_directory
