Description

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.
