df_vxfs

df_vxfs(1M)															       df_vxfs(1M)

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.

EXAMPLES

       Report the number of free disk blocks for all mounted file systems:

       Report the number of free extents of each size, for all mounted VxFS file systems:

       Report the number of free files for all mounted VxFS file systems:

       Report the total allocated block figures and the number of free blocks, for all mounted file systems:
