I have changed /usr/bin/keystone-all file on each controller node. I have added one line:
147 config.setup_logging()
this change regard to https://bugs.launchpad.net/mos/+bug/1413341

Deployment has been passed successfully, but during full rally test primary controller node has been marked as offline. Also this node is unreachable via ssh.

[root@fuel ~]# ssh node-19
Warning: Permanently added 'node-19' (RSA) to the list of known hosts.
Write failed: Broken pipe

But at the moment I have one opened ssh session which gives the able to execute some commands.

here is output of top command:

"rabbitmqctl cluster_status" and "rabbitmqctl list_queues" commands just hang on this node

from other controller node:
