obdfilter-survey test 3a hangs on OST umount. The last thing we see in the client test_log for test 3a is unmounting OST1 on onyx-34vm8.

From the OST dmesg log, we see

obdfilter-survey test 3a started hanging on OST umount from, at least, October 11. The OST umount only hangs (for this test) during interop testing; for example 2.10.2 RC1 and 2.9.0.
