Clock sync between nodes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Running a two node replicated volume with GlusterFS 3.5.3, I've noticed that one node couldn't reach its time server, and is now about 80 sec behind the other node.
I'm a bit afraid of running a ntpdate to force the clock back on sync, could such a big jump forward cause gluster to think the files are out dated and start a heal ? Only meta-data heal maybe ? This cluster is hosting critical data, and I don't want to take a risk.

What could happen if I just leave it as is, with a big time offset between the two nodes ? Could this explain why I see continuous healed file (see my previous thread "info healed show files being healed all the time") ?

Thanks for your advice.

Cheers
Daniel
