I think it is a decent assumption that NTP is installed on the hypervisors. I assume that not having NTP can cause more issues but I wouldn't focus on fixing them. There is an option to configure NTP in PackStack. I'm closing this bug, feel free to reopen if you think I missed something. I have two issues with closing this as WONTFIX: * I think there should be some informative message in some log about that the time skew is the issue. * Only one node which has time skewed for whatever reason, like some problem when connecting some external NTP server, causes malfunction of whole stack. The second item in comment 4 seems like a real bug. I think we should at least try to reproduce this behaviour. Brent, I would check what happens if the administrator fixes the skewed time on the node, does everything goes back to normal? I think answering the above question could help us determine the priority of this bug. Agreed. Jaroslav, can you confirm if setting the time back to being in sync resolves the flapping. Also it would be interesting to retest. I couldn't get things to "flap" in a simple vm based multinode environment using Havana and upstream trunk code. Some of the agent state update code has been modified quite a bit so this might have been resolved. Since this is not critical we can look into this in the Icehouse time frame. |
