The sub-test test_bonnie failed with the following error:

test failed to respond and timed out

With OSTCOUNT=2, sanity-benchmark test bonnie passed:

Let's close this ticket.

sanity-benchmark test_bonnie also hit the same failure:
https://maloo.whamcloud.com/test_sets/f407fb0c-305a-11e3-b28a-52540035b04c

We'll see whether the timeout failure can disappear after TEI-790 is resolved.

I believe this is another zfs performance issue a la LU-2887.

The completion times for this test when it passes on ZFS are in the range 1800-3400 which out-lairs on either side, so those that timeout are just running long and no a failure per se.
