Description
We had a deadlock recently on an MDS at NOAA. The threads were mostly waiting for a mutex in mds_lookup and for the quota master lock in target_handle_dqacq_callback, with some other ldiskfs lock waiters in there too.
I will attach the bt, bt -f, log, and kern.log files. Let me know if there is anything else I should get from the vmcore.
