IV60235: JFS2 FS MARKED CORRUPT WHEN USING FIND COMMAND NEEDING FSCK RUN

APAR status

• Closed as program error.

Error description

• A JfS2 FS can be marked corrupt when accessing a lot of
  files(been seen with the
  use of the find command). This results in fsck needing to
  be run the
  next time the FS needs to be mounted. The error report is
  updated with symbol
  addresses indicating problem happened  with the following
  stack :
  
  diRead+000354
  iGet+000DF8
  j2_lookup+000428
  vnop_lookup+0001D4
  lookuppn+000918
  statxat+000320
  
  It is caused by accessing stale metadata.  It occurs
  rarely since
  most of the time the metadata has acceptable data even
  though
  it is stale.  However when it does not have acceptable
  data the FS can be
  marked as corrupt.  The fix of the problem avoids stale
  data from being accessed
  

Local fix

• No local fix.
  

Problem summary

• *************************************************************
  * USERS AFFECTED:
  * Systems running the 5300-12 Technology Level with
  * bos.mp between and including the 5.3.12.7 and 5.3.12.9
  * levels and bos.mp64 between and including the 5.3.12.7 and
  * 5.3.12.9 levels.
  *************************************************************
  * PROBLEM DESCRIPTION:
  * Customers using jfs2 may see errpt showing the filesystem
  * requires fsck with an error code of 0x34 (ESTALE).
  * LABEL:          J2_FSCK_REQUIRED
  * ERROR CODE
  * 0000 0034
  * However when fsck is run, it reports that no corruption was
  * encountered.
  *
  * In this case, you may be experiencing a bug in jfs2 code
  * that can cause it to mistakenly mark the filesystem as
  * needing repair when it is not really needed.  If the
  * situation is encountered, you should:
  *  1. install this fix to ensure jfs2 will not mark the
  *     filesystem dirty by mistake
  *  2. unmount, run fsck, and remount to mark the filesystem
  *     clean
  *************************************************************
  * RECOMMENDATION:
  * Install APAR IV60235.
  * Prior to fix availability, an interim fix is available from
  * either
