APAR status

  • Closed as program error.

Error description

  • fsck fails to fix the JFS2 corruption involving extended
    attributes. If there is a JFS2 metadata corruption and FS
    has EAs enabled, fsck might not fully fix the corruption
    and hence leave the EAs in erroneous state resulting the
    corruption to be as it is. This will result in corrupted
    EA metadata to re-appear everytime the backup of the FS
    is used.
    

Local fix

  • N/A
    

Problem summary

  • Repeated filesystem corruption will be seen only, if there
    is ever a EAV1 corruption and continue use of EAV1s.
    
    Mostly fsck will complain about "cross linked" blocks
    or "EAV1 data format errors", but other variations of
    corruptions possible, including system crash.
    

Problem conclusion

  • Remove all assoicated data from the inode during cleanup of
    a corurpted EAV1
    

Temporary fix
