replay-ost-single test_5 hangs after starting iozone and waiting for the failed OST to start. Logs for this hang are at https://testing.hpdd.intel.com/test_sets/fd70c104-dae4-11e7-8027-52540065bddc There's not much in the console and dmesg logs to determine what the issue is. The last thing seen after failing the OST in the test log on the client Failing ost1 on trevis-3vm3
