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
[24240.212638] INFO: task umount:26551 blocked for more than 120 seconds. [24240.213441] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
