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

  • File system being marked as corrupt when doing backup and
restore (or long running finds)  when the inode cache is full.

Problem conclusion

  • correct a check on the read into the inode cache.

Temporary fix
