NAME

       setext - set VxFS extent attributes

SYNOPSIS

       extent_size] flag] reservation] file

DESCRIPTION

       specifies a fixed extent size for a file, and reserves space for a file.  The file must already exist.

       In  some cases, fsadm may reorganize the extent map of a file in such a way as to make it less contiguous.  However, it does not change the
       geometry of a file that has a fixed extent size.

   Options
       recognizes the following options:

	      Specify a fixed extent size.
			     extent_size is the number of file system blocks to allocate for the extent.  An extent_size of zero cancels  previous
			     fixed-size  extents  for the file and uses the default extent allocation policy.  See vxtunefs(1M) for information on
			     extent size parameters.

	      The available allocation flags are

			     Specify that all extents must be aligned on
				    extent_size boundaries relative to the start of allocation units.

			     Immediately incorporate the reservation
				    into the file and update the file's on-disk inode with size and block count information that is  increased	to
				    include  the  reserved  space.   The  space added to the file is not initialized.  Only users with appropriate
				    privileges can use the option.

			     Specify that the reservation must be allocated contiguously.

			     Specify that the file may not be extended after the preallocated space
				    is used.

			     Specify that the reservation is not a persistent attribute of the file.
				    Instead, the space is allocated until the final close of the file, when any space not  used  by  the  file	is
				    freed.  The temporary reservation is not visible to the user (via getext(1M) or the ioctl, for example).

			     Specify that the reservation is reduced to the current file size
				    after the last close by all processes that have the file open.

	      Specify the VxFS file system type.

	      Preallocate space for
			     file.  reservation is specified in file system blocks or the actual size in bytes.

	      Echo the completed command line, but do not execute the command.
			     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.

   Operands
       recognizes the following operand:

	      file	     Name of an existing VxFS file.

   Notes
       is available only with the HP OnLineJFS product.

       You can specify multiple flags by entering multiple instances of on the command line.

       You must specify the allocation flags with either the or option.

       Only the and allocation flags are persistent attributes of the file and therefore visible via getext(1M) or the ioctl.  Although is  not  a
       persistent  attribute  of  the file, it is visible until it is cleared during the final close of the file.  Other allocation flags may have
       persistent effects, but are not visible as allocation flags.

       In some cases, may reorganize the extent map of a file in such a way as to make it less contiguous.  However, it will not change the geome-
       try of a file that has a fixed extent size.

       For  the or options, you can specify the size in number of file system blocks or in bytes.  A numeric value indicates file system blocks, a
       numeric value with a suffix specifies the size in bytes: for kilobytes, for megabytes, or for gigabytes.

NAME

       df_vxfs: df - report number of free disk blocks on a VxFS file system

SYNOPSIS

       [special|directory]...

DESCRIPTION

       prints the number of free blocks and free inodes in VxFS file systems or directories based on the counts kept in the super-blocks.

       VxFS dynamically allocates inodes from a pool of free blocks.  The number of free inodes and blocks reported by is an estimate based on the
       number of free 8K or larger extents and the current ratio of allocated inodes to allocated blocks.  (Extents smaller than  8K  may  not	be
       usable  for all types of allocation, so does not count free blocks in extents smaller than 8K.)	Allocating additional blocks may therefore
       decrease the count of free inodes and vice versa.

       If the operand to is a special device name, the file system can be an unmounted or mounted file system  (for  example,  If  you	specify  a
       directoryname, displays information for the file system at that mount point.  If neither special nor directory is specified, the free space
       on all of the mounted file systems is printed.

   Options
       recognizes the following options:

	      Report only the number of kilobytes free.

	      Report the number of files free.

	      Report only an actual count of the blocks in the free list
			     (free inodes are not reported).  When this option is specified, reports on raw devices.

	      Specify the file system type

	      Report the entire
			     statvfs(2) structure.

	      Report the total number of inodes, the number of free inodes, number of used inodes
			     and the percentage of inodes in use.

	      Report the allocation in kilobytes.

	      Report on local file systems only.

	      Report the file system name.  If invoked with no other options this
			     option prints a list of mounted file system types.

	      Print the number of free extents of each size.
			     Free extents are always an integral power of two in length, ranging from a minimum of one block to the maximum extent
			     size supported by the file system.

	      Report the total allocated block figures and the number of free blocks.

	      Report the percentage of blocks used, the number of blocks used and the number
			     of blocks free. This option cannot be used with other options.

	      Echo the completed command line, but performs no other action.
			     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.

       There are a number of options that specify output formats, some combinations of which are incompatible.	If an incompatible combination	is
       specified, one of the options will override the other(s).

   Operands
       recognizes the following operands:

	      directory      Name of the mount point from which the VxFS file system is accessed.

	      special	     Device name, which contains a mounted or unmounted VxFS file system.
