df(1M_VXFS)                    (VXFS)                    df(1M_VXFS)


       NAME
             df (vxfs) - report number of free disk blocks and inodes for
             vxfs file systems

       SYNOPSIS
             df  [-F vxfs] [generic_options] [-o s] directory | special . . .

       DESCRIPTION
             generic_options are options supported by the generic df
             command.

             The df command prints out the number of free blocks and free
             inodes in vxfs file systems or  directories by examining the
             counts kept in the super-blocks.

             Extents smaller than 8K may not be usable for all types of
             allocation, so df does not count free blocks in extents below
             8K when reporting the total number of free blocks.

             Since VxFS 2.0 dynamically allocates inodes from the pool of
             free blocks, the number of free inodes and blocks reported by
             df is an estimate based on the number of free 8K (or larger)
             extents and the current ratio of allocated inodes to allocated
             blocks. Allocating additional blocks may therefore decrease
             the count of free inodes, and vice versa.

             The special device name (for example, /dev/dsk/c0b0t1d0s5) or
             mount point directory name (for example, /usr) must be
             specified.  If directory is a directory name, the report
             presents information for the device that contains the
             directory.

             The options are:

             -F vxfs   Specify the vxfs FSType.

             -o        Specify vxfs file system specific options.  The
                       following option is available:

                       s       Print the number of free extents of each
                               size.  Free extents are always an integral
                               power of 2 in length, ranging from a minimum
                               of 1 block to a maximum of the size of an
                               allocation unit.
