      We do OSS failover, trigger LFSCK:

      

      

      lctl lfsck_start -M soaked-MDT0000 -s 1000 -t all -A{code]
      


      The lfsck start hangs, lfsck is not started, the clients wedge in state 'comp' the entire system wedges. I have dumped Lustre Logs from all MDS, attached.  I have crash-dumped all the MDT nodes and the dumps are available on Spirit. lfsck_layout is unkillable.
