Description

This issue was created by maloo for Oleg Drokin <[e-mail]>

This issue relates to the following test suite run: https://maloo.whamcloud.com/test_sets/b80d0642-f703-11e1-b320-52540035b04c.

The sub-test test_61c failed with the following error:

Restart of ost1 failed!

Info required for matching: replay-single 61c

Seems to be some race in the test script, fail_timeout code woke up one second after userspace attempted to unmount/remount (and failed with 'already mounted'). here's part of OST log:
