Problem summary

  • Symptoms vary, but commonly result in a system crash with a
    stack trace ending similar to:
    
    dbUpdatePMap+000670
    txFreeMap+000264
    xtFreeMap+00023C
    txUpdateMap+000240
    txCommit+000774
    

Problem conclusion

  • Do not allow new filesystem metadata transactions to start (and
    fail) as long as there are JFS2 log writes failing. If the
    storage subsystem failure is temporary, allow new transactions
    to start once it recovers.
