Description
The following call stack during autotesting on Maloo for http://review.whamcloud.com/#/c/20546/. My new test is standing up 3 MDTs with non-consecutive indices and a couple of OSTs. The method I am using to start the "custom" filesystem seems to be consistent with how other tests start their "custom" filesystems.
Link to the Maloo test session results is https://testing.hpdd.intel.com/test_sessions/4599d8d8-6108-11e6-906c-5254006e85c2.
The LBUG is preventing the filesystem from coming up. Any suggestions?
