Nodes in warmup even though they really aren't

[Lasse Schou]

Hi,

When I have multiple nodes warming up in my cluster, I often see that thay all go green simultaneously when the last node is finished warming up. I've tried to get the warmup information from cbstats (why isn't there detailed warmup stats in the server nodes overview?), and I can see that some nodes have fully loaded all buckets, yet they are still yellow in the web UI.

Is this expected? And what consequences does this have - are the servers serving keys and view data is all buckets are loaded, even though they appear to be in warmup?

Thanks,

Lasse

Yes. We'll enable traffic only when all nodes are up and healthy. That's precaution to be sure that all nodes agree on vbucket map. There's ticket for improving it. See http://www.couchbase.com/issues/browse/MB-4030
