Open Stack

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.
