 NAME    [Toc]    [Back]
      pfs_fstab, mtab - static file system mounting table, mounted file
      systems table

 SYNOPSIS    [Toc]    [Back]
      /etc/pfs_fstab

      /etc/mtab

 DESCRIPTION    [Toc]    [Back]
      The /etc/pfs_fstab file contains entries for CD-ROM file systems and
      disc images to mount using the pfs_mount(1M) command, which is
      normally invoked by rc(1M) script at boot time.  This file is used by
      various utilities such as pfs_mount and pfs_umount.

      The /etc/mtab file contains entries for file systems currently
      mounted, and is read by programs using the routines described in
      getmntent(3X).  umount (see mount(1M)) removes entries from this file.

      Each entry consists of a line of the form:

           filesystem    directory    type    options    freq    pass

      filesystem  is the pathname of a raw or block-special device, the name
                  of a remote file system in host:pathname form, or the name
                  of a file created with MakeDisc.

      directory   is the pathname of the directory on which to mount the
                  file system.

      type        is the file system type, which can be one of:
                  pfs-iso9660       to mount a device as iso9660.
                  pfs-hsfs          to mount a device as hsfs.
                  pfs-rrip          to mount a device as rrip.
                  pfs-nfs           to mount an exported PFS file system

      options     contains a comma-separated list (no spaces) of mounting
                  options, some of which can be applied to all types of file
                  systems, and others which only apply to specific types.

                  options valid on all file systems:

                  ro                 Even if not specified, this option is
                                     implied.
                  suid|nosuid        Setuid execution allowed or disallowed.
                  bg|fg              If the first attempt fails, retry in
                                     the background, or, in the foreground.
                  retry=n            The number of times to retry the mount
                                     operation.
                  rsize=n            Set the read buffer size to n bytes.

                  timeo=n            Set the PFS timeout to n tenths of a
                                     second.
                  retrans=n          The number of PFS retransmissions.
                  soft|hard          Return an error if the server does not
                                     respond, or continue the retry request
                                     until the server responds.
                  intr               Allow keyboard interrupts on hard
                                     mounts.

                  options specific to iso9660 and hsfs file systems:

                  xlat=xlat_flags     xlat_flags is a colon (:) separated
                                      list of translation options.
                                      Currently supported are no_version,
                                      dot_version, lower_case, and unix.

      freq        is the interval (in days) between dumps.  For a PFS file
                  system, this should be 0.

      pass        is the fsck(1M) pass in which to check the partition.  For
                  a PFS file system, this should be 0.

      A pound-sign (#) as the first character indicates a comment line which
      is ignored by routines that read this file.  The order of records in
      /etc/pfs_fstab is important because fsck, mount, and umount process
      the file sequentially; an entry for a file system must appear after
      the entry for any file system it is to be mounted on top of.

 EXAMPLES    [Toc]    [Back]
      /dev/sr0 /cd-rom pfs-iso9660 ro,suid 0 0

      example: /home/user /home/user pfs-nfs ro,hard,fg 0 0

 WARNINGS    [Toc]    [Back]
      PFS is obsolete and no longer supported on any HP-UX release.
      Delivery of PFS interfaces will be discontinued in the next HP-UX
      release.

      PFS, from Young Minds, Inc. (now defunct), was originally adopted by
      HP to provide accessibility to Rock Ridge Interchange file system
      format on CD-ROM file systems.  The equivalent functionality is now
      provided via the HP-UX CDFS file system type and HP-UX's standard file
      systems commands.

      PFS has known functionality and performance problems.  HP customers
      are urged to stop using the PFS interfaces, including these
      interfaces, /etc/pfs_fstab and /etc/mtab.  Customers should move to
      accessing all CD-ROM file system formats by using the standard HP-UX
      commands, specifying the file system type as cdfs.  For example, to
      mount a CD-ROM file system, use:




 Hewlett-Packard Company            - 2 -      HP-UX 11i Version 2: Sep 2004






 pfs_fstab(5)                                                   pfs_fstab(5)
                                  OBSOLETED



           mount -F cdfs /dev/dsk/c0t0d4 /cdrom

      There is no need to treat the cdfs file system type differently from
      any other file system type, therefore no special daemons or commands
      are required to access the variety of CD-ROM file system formats.

      See mount(1M) and mount_cdfs(1M).
