IJ36237: JFS2 FILE SYSTEM CAN GET MARKED CORRUPT AFTER EXTENDING FS. APPLIES TO AIX 7200-05

 

APAR status

  • Closed as program error.

Error description

  • Right after a file system is extended it is possible that
    the same file system
    could be marked corrupted and error message sent to the
    error report to run fsck on it
    This is due to a race condition on the setting of the new
    size of the
    file system and has not been seen very often. So it is
    considered a
    rare occurrence
    

Local fix

Problem summary

  • An FS could be incorrectly marked corrupt soon after it was
    extended. J2_DMAP_CORRUPT and J2_FSCK_REQUIRED entries would
    be found in the errpt. They could be immediately preceeded by
    a J2_FS_FULL log.
    

Problem conclusion

  • Ignore hint value if it appears to be out of bounds, and
    switch to the default allocation path.
    

Temporary fix
