[LU-11249] recovery-small test 29a hangs on unmount/mount

Tue, 14 Aug 2018 15:29:06 +0000

recovery-small test_29a times out with logs for the failed test session at https://testing.whamcloud.com/test_sets/23dc8976-9d91-11e8-87f3-52540065bddc.

The MDS console log shows some issue not seen when this test succeeds. First, we see issues when we try and unmount the MDT
