Dashboard Message - Time on servers not in sync with Grid Controller

[SeanCurry]

Folks,
New to applogic, and just did a grid install, and got the the following message on the console (in 2.9.9):

Mar 28 - The time on the following servers are no longer in sync with the grid controller: srv2, srv3, srv4, srv5. Appliances running on these servers may report the incorrect time. Please contact technical support.

This is our 3rd or 4th install, and the first time I'd seen the message, so I thought I'd see if anyone had any ideas.

Thanks!

I pushed the grid controller to one of the other servers, just to see if it resovles it (with the thinking that the server the grid controller was on was the only one not reporting the issue). Seems to have worked so far.

There are a few things that can cause this problem. Sometimes, if the time on the servers are off to far they cannot automatically update via NTP. The system is setup for the controller to get NTP from a live NTP server online, and each node is configured to sync against the controller. So, the best place to start is to find out what is actually off and by how much.

Have you restarted the grid since it was built?

You can also do a manual sync(on the controller, and the nodes) by first stopping the ntpd service('service ntpd stop'), using ntpdate to sync the time(on controller: 'ntpdate 0.pool.ntp.org' ; on a node: 'ntpdate 192.168.<grid id>.254' ), and then restarting the ntpd service('service ntpd start').
