NAME
       extendfs_vxfs: extendfs - extend VxFS file system size

SYNOPSIS
       size] special

DESCRIPTION
       If  the	VxFS file system image created on special does not use all of the available space, increases the capacity of a VxFS file system by
       updating the file system structure to include the extra space.

       special specifies the device special file of either a logical volume or a disk partition.  If special refers to a mounted file system,  you
       must unmount special before running (see mount(1M)).

       The Version 5 disk layout supports file systems up to 32 terabytes.  The size to which a Version 5 disk layout file system can be increased
       depends on the file system block size:

	    o  1024 bytes  4,294,967,039 sectors (4 TB)

	    o  2048 bytes  8,589,934,078 sectors (8 TB)

	    o  4096 bytes 17,179,868,156 sectors (16 TB)

	    o  8192 bytes 34,359,736,312 sectors (32 TB)

       The Version 6 disk layout supports file systems up to 256 terabytes.  The size to which	a  Version  6  disk  layout  file  system  can	be
       increased depends on the file system block size:

	    o  1024 bytes  34,359,736,312 sectors (32 TB)

	    o  2048 bytes  68,719,472,624 sectors (64 TB)

	    o  4096 bytes 137,438,945,248 sectors (128 TB)

	    o  8192 bytes 274,877,890,496 sectors (256 TB)

       The  maximum file system size supported is 2 terabytes.	For a file system's size to be increased to 32 terabytes or greater, the file sys-
       tem must be on a 64-bit kernel operating system and must reside on a VERITAS Volume Manager volume.

       If the file system resides on a volume set, will fail.  Use the fsvoladm(1M) command to extend a multi-volume file system.

       When the file system size is grown with the extendfs command, the intent log size is not automatically increased.

   Options
       recognizes the following options:

	      Specify the VxFS file system type.

	      Query	special to determine the size.	The file system is not extended.

	      Specify the number of
			blocks to add to the file system.  If size is omitted, the maximum possible size is used.

	      Specify verbose mode, which displays the resulting size of file system
			along with output of the newly sized file system.  Without there is no output.

   Operands
       recognizes the following operand:

	      special	The device special file of either a logical volume or a disk partition.  If special refers to a mounted file  system,  you
			must unmount special before running (see mount(1M)).

EXAMPLES
       This example shows how to increase the capacity of a file system created on a logical volume.
