Comment 3 for bug 1417685

The deployment failed as the only mysql backend went down in the middle of primary-controller deploy:
2015-02-03T10:29:20.877547+00:00 alert: Server mysqld/node-1 is DOWN, reason: Layer7 timeout, check duration: 10000ms. 0 active and 0 backup servers left. 3 sessions active, 0 requeued, 0 remaining in queue.

And the failure was caused by some OS issues not related to the Openstack deployment:
