NAME
     fsck_s5fs - file system consistency  check  and  interactive
     repair

SYNOPSIS
     fsck -F  s5fs  [ generic_options ]  [ special ... ]

     fsck -F  s5fs  [ generic_options ]  [ -o specific-options  ]
     [ special ... ]

DESCRIPTION
     fsck audits and interactively  repairs  inconsistent  condi-
     tions  on  file systems.  A file system to be checked may be
     specified by giving the name of the block or character  spe-
     cial  device  or  by giving the name of its mount point if a
     matching entry exists in  /etc/vfstab. If no special  device
     is  specified,  all s5 file systems specified in the  vfstab
     with a fsckdev entry will be checked.

     In  the  case  of  correcting  serious  inconsistencies,  by
     default,   fsck asks for confirmation before making a repair
     and waits for the operator to respond either yes or  no.  If
     the operator does not have write permission on the file sys-
     tem,  fsck will default to a -n (no corrections) action. See
     fsck(1M).

     Repairing some file system  inconsistencies  may  result  in
     loss  of  data.  The amount and severity of data loss may be
     determined from the diagnostic output.

     fsck automatically corrects innocuous  inconsistencies  such
     as  unreferenced  inodes,  missing  blocks in the free list,
     blocks appearing in the free list  and  also  in  files,  or
     incorrect   counts  in  the  superblock  automatically.   It
     displays a message for  each  inconsistency  corrected  that
     identifies  the  nature  of the correction on which the file
     system took place.  After  successfully  correcting  a  file
     system,  fsck prints the number of files on that file system
     and the number of used and free blocks.

     Inconsistencies checked are as follows:

        o  Blocks claimed by more than  one  inode  or  the  free
           list.

        o  Blocks claimed by an inode or the  free  list  outside
           the range of the file system.

        o  Incorrect link counts.

        o  Incorrect directory sizes.

        o  Bad inode format.

        o  Blocks not accounted for anywhere.

        o  Directory checks, file pointing to unallocated  inode,
           inode  number  out  of range, absence of  `.' and `..'
           entries in any directory.

        o  Superblock checks: more blocks for inodes  than  there
           are in the file system.

        o  Bad free block list format.

        o  Total free block and/or free inode count incorrect.

     Orphaned files and directories (allocated but  unreferenced)
     are, with the operator's concurrence, reconnected by placing
     them in the  lost+found directory. The name assigned is  the
     inode  number.   If the lost+found directory does not exist,
     it is created.

OPTIONS
     See generic  fsck(1M) for generic_options  and  details  for
     specifying special.

     -o    Specify s5 file system specific options. These options
           can  be  any combination of the following separated by
           commas (with no intervening spaces):

           f or F
                 Fast check; duplicate blocks and free list check
                 only.

           l     After  all  other  output  is  done,  print   i-
                 number/pathname   correspondences   for  damaged
                 files.

           t scratchfile
                 If there is insufficient memory and a  temporary
                 file is necessary to complete file system check-
                 ing, use scratchfile as the temporary file.

           T scratchfile
                 Same as above.

           s cyl:skip
                 If it is necessary to rewrite (salvage) the free
                 block  list  to correct an inconsistency, inter-
                 leave the blocks such that, to the extent possi-
                 ble  within  each  group of cyl consecutive free
                 blocks, the interval  between  blocks  is  skip.
                 For  example, with an interleave of 8:3, in each
                 group of  eight  consecutive  free  blocks,  the
                 order on the free list would be 1 4 7 2 5 8 3 6.
                 If no cyl:skip is given,  the  value  is  either
                 taken  from  the  superblock, or, if unspecified
                 (either has a value of 0), 400:7 is  used.   For
                 obscure  historical reasons, interleave specifi-
                 cation of ``3'' and ``4'' (without  colons)  are
                 taken to mean 200:5 and 418:7, respectively.

           S cyl:skip
                 Same as above, except  rewrite  the  free  block
                 list unconditionally.

           q     Quiet; produce less verbose output.

           D     Perform more extensive directory  checking  than
                 normal.

           p     (``preen'') Check and fix the file  system  non-
                 interactively.  Exit  immediately  if there is a
                 problem requiring intervention.

           ?     Print usage message.

NOTES
     It is usually faster to check the character  special  device
     than the  block special device.
