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
