Comment 6 for bug 1426375

My current understanding is that https://github.com/stackforge/fuel-qa/commit/f75ee6796164b25497fe10010bbaa671d31d842d not only added this test to BVT_2, but also changed the test itself a lot and now it can fail even if the environment is perfectly OK.

As it's stated in the description, we start tests before cinder-scheduler understands there is available space in Ceph.
