[systests] Nodes went offline during the system tests

It is caused by performance issues of a system tests. It takes a lot time to suspend slave nodes. Thereby the master node may detect offline / suspended nodes before it suspended.

Tatyana, could you please set 'Confirmed' status if bug is successfully reproduced?

No I can not, because I have not chance to reproduce it

Looks like this is problem with performance. It is reproduced when user tries to deploy multinode HA environment (with 4+ nodes) simultaneously. The root of this problem in hardcoded timeouts for different operations in Fuel manifests. Need to check on the other environment.

Anastasia, can you please look on this problem with the system tests? Anastasia Naboikina can provide more detaield information abbout the root of this problem.

This problem was fixed in systests, actually test wait online status for nodes.

Have the same issue on 214 iso.

My suggestion: after snapshot reverting and ntp synchronization we get big time different between last node agent report and actual time. Aslo we have background process in Nailgun which periodically (every 5 minuts) check database and set state of nodes to offline if no reports from nailgun agent performed between runs.

Because this process do it in background, we can get moment, when we start deploy and in same time at least one in cluster set as offline.

Solutions:
 - after ntp synchronization run nailgun-agent. It will actualize nodes status and prevent unexpected offline status (preferable);
 - update datetime field in nodes table to actual in master node which also prevent such behavior.
