Thanks a lot for the reply, John. Yes I understand that time is really important for cluster setup, that's why I was panicking and looking for alternatives when I found time drifting while ntpd was still on. So I was planning to do a ``ntpdate w.x.y.z '' every 2 mins in order to keep time in sync.
Would want to investigate this. My upstream time server seems fine, its on a baremetal. Many other servers sync with this one too. Also only one controller had issues with time. Kind of stuck here, as I have no idea why one node's ntpd would fail :( Regards, Raja.
