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.

NAME

       newfs_vxfs: newfs - create a new VxFS file system

SYNOPSIS

       disk_type] swap]
	      [mkfs_vxfs_options] special

DESCRIPTION

       builds a VxFS file system by invoking

       special specifies a character (or raw) file (for example, or

   Options
       recognizes the following options:

	      Reserve space for boot programs past the end of the
			     file  system.  If the file is present on the system, sufficient space to accommodate that file is reserved; otherwise
			     691 kilobytes are reserved.  This option decreases the size of the file system being created.  This option cannot	be
			     used if the file-system size is also specified using (see options below).

	      Specify the file-system type

	      Use disk parameters from the
			     disk_type	named  in  This option is provided for backward compatibility with previous HP-UX releases. Any parameters
			     specified on the command line will the corresponding values in Any values not specified in the command line  and  not
			     shown in are defaulted.

	      Reserve	     swap  megabytes  of swap space past the end of the file system.  This option decreases the size of the file system to
			     be created by the specified number of megabytes.  cannot be used if the file-system size is also specified using (see
			     options below).

	      Specify verbose mode.
			     prints out its actions, including the parameters passed to

	      Echo the completed command line, but do not execute the command.
			     If not valid, prints an error message.  The command line is generated by incorporating the user-specified options and
			     other information derived from This option allows the user to verify the command line.

       NOTE: You can specify the and options in the same command line.	In that case, both the requested swap space and the space needed for  boot
       programs are reserved.  These options are used when the file system size is defaulted to the size of the entire disk.

   mkfs_vxfs Options
       The following additional command-line options can be used to override default parameters passed to

	      File system block size in bytes. The default value is
			     1024 bytes for systems smaller than two terabytes.  For Version 5 disk layout file systems larger than two terabytes,
			     the maximum file system size is dependent on the block size.  A four terabyte file system requires a 1K  block  size,
			     An  eight	terabyte  file	system requires a 2K block size, a 16 TB file system requires a 4K block size, and a 32 TB
			     file system requires an 8K block size.

	      Valid only for the Version 4 and 5 disk layouts.
			     This option controls the largefiles flag for the file system.  If is specified, the bit is set and  files	two  giga-
			     bytes  or	larger can be created.	If is specified, the bit is cleared and files created on the files system are lim-
			     ited to less than two gigabytes.  The default is See mkfs_vxfs(1M), mount_vxfs(1M), and fsadm_vxfs(1M).

	      File system size in
			     blocks (defined in The default value is the size of the entire disk or disk section, minus any  swap  or  boot  space
			     requested.   The  size specifies the number of sectors in the file system.  By default, size is specified in units of
			     sectors.  However, you can append a suffix to size to indicate another unit of measure.  Append or to  indicate  that
			     the value is in kilobytes, or to indicate megabytes, or or to indicate gigabytes.

   Operands
       recognizes the following operand:

	      special	     A character (raw) file.

EXAMPLES

       To create a VxFS file system on or and reserve 40 megabytes of swap space.

FILES

       Disk description file.
