Hello; Long time lurker here and first time posting.
I have a couple of clusters that are beefy 128GB of ram each 16+ cores per host and 3 servers per cluster and a few different clusters in different environments. All running off 10G fiber to a V7000 SAN appliance.
Now I built these clusters a few months back. So far its been fairly painless process. Have a few hard hitting vm's on them with way more to come.
When I move VM's from host to host my servers are running into NTP drift issues, some nearly 5 seconds. This is on esx5.1 on IBM x series servers. These servers are RHEL/centos 6.3. The guest os's are syncing to a local NTP source not the web.
No matter how I search the only mention I see about NTP drift are from 2004 for esx 3.x if im not mistaken. Anyone encountered this? Anyone have advice? To be fair I do not have vmware tools on the hosts as I really don't see much benefit to them.
Thank you.
