 NAME    [Toc]    [Back]
      df_vxfs: df - report number of free disk blocks on a VxFS file system

 SYNOPSIS    [Toc]    [Back]
      df [-F vxfs] [-V] [-befgiklntv] [-o s]
           [special | directory ...]

 DESCRIPTION    [Toc]    [Back]
      df 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 df 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 df 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 df is a special device name, the file system can be
      an unmounted or mounted file system (for example, /dev/dsk/c0t1d0).
      If you specify a directoryname, df 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    [Toc]    [Back]
      df recognizes the following options:

           -b             Report only the number of kilobytes free.

           -e             Report the number of files free.

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

           -F vxfs        Specify the file system type (vxfs).

           -g             Report the entire statvfs(2) structure.

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

           -k             Report the allocation in kilobytes.

           -l             Report on local file systems only.

 df_vxfs(1M)                                                     df_vxfs(1M)




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

           -o s           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.

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

           -v             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.

           -V             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 /etc/fstab.  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    [Toc]    [Back]
      df 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    [Toc]    [Back]

           df -F vxfs -e
