  13 # Name :
  14 #        bcheckrc (afs) - /sbin/fs/afs/bcheckrc
  15 #
  16 # Description
  17 #       This file contains scripts/commands necessary to checks
  18 #       the afs file systems before mounting.
  19 #
  20 #       It should be invoked by the generic bcheckrc script only.
  21 #
  22 # Input Parameters:
  23 #       None
  24 #
  25 # Expected results:
  26 #       see description.
  27 #
  28 # Side effects of this test:
  29 #       none
  30 #
  31 # Supporting files and Relationship:
  32 #        i) various "/sbin/fs/afs" commands are used by this script.
  33 #       ii) generic bcheckrc scrtipt located in the /sbin
  34 #           directory invokes this script.

  40 # Description - This function will check (fsck) all the afs file systems
  41 # in the static file system table, /etc/fstab.
  42 #
  43 # Result values - status = 0 for success
  44 #                 status = non-0 for failure
  45 #
  46 # Used (exclusively) by - /sbin/bcheckrc's fsck_afs portion

  51 #       ROOTSHELL   - is the command that gives the user a shell in which
  52 #                     to run fsck interactively.  Someday fsck -y should
  53 #                     be fixed to give the right answers to the questions,
  54 #                     rather than always "yes", so this error-prone
  55 #                     interactive fixing business can go away entirely.

  63
  64 #
  65 #       In the remaining part of the function is devoted to the actual
  66 #       cleaning of the afs file systems.
  67 #
  68 #               1) run fsck -m and determine if any afs file systems
  69 #                  need cleaning.
  70 #
  71 #               2) check exit status of fsck -m -
  72 #
  73 #                       0 - indicates (and lists) that  this afs file
  74 #                           system was verified clean.  Continues to
  75 #                           boot.
  76 #
  77 #                       * - indicates and lists the file systems that
  78 #                           were not properly shutdown.  File systems
  79 #                           that are corrupt should be fixed before
  80 #                           continuing with the boot.
  81 #
  82 #
  83 #               3) exit the function with the appropriate return status.
  84 #
  85 #
  86 #               When the file systems are corrupt the following steps are
  87 #               taken ...
  88 #
  89 #                       1) fsck_afs(1M) command is invoked using the
  90 #                       following command line - "/sbin/fsck -F afs -P -f"
  91 #                       (refer to the fsck_afs(1M) man page)
  92 #
  93 #                       2) The following actions are taken according to
  94 #                       the appropriate return values ...
  95 #                                0 - the corrupt file system was fixed.
  96 #                                    Continue with boot'ing.
  97 #                                * - could not automatically fix the
  98 #                                    corrupt file system, going into
  99 #                                    manual mode (shell).
