Nick, The line " get_object_context: obc NOT found in cache" should be fine, it will be rare (even after obc cache implementation) you will have a hit during random workload. Is the second IO on the pool you are having problem ? I saw huge wait time there during getattr completion. In the first case, it is ~64ms and in second case ~1 sec !! Unfortunately, you didn't enable filestore log level to 20 , that's why I couldn't able to say where it is taking time..Please post that.. But, I think it is the problem while retrieving xattr '_' and '_snapset'...

Release is Hammer, so I can probably drop that setting then. I have hopefully managed to capture a couple of slow IO's on an idle cluster, does the below look about right to you? I can see there is a delay after this entry " get_object_context: obc NOT found in cache", is that indicative of anything? 2015-06-29 12:35:19.551447 7fd8a7d44700 15 osd.1 26335 enqueue_op 0x6b9a4d00
