Turning 1 node off kills whole cluster


(kurtis) #1

While investigating an outage on our production cluster, I noticed that if I turn off one of the data nodes, it kills the entire cluster. The cluster immediately becomes operational when I turn it back on.

What is going on? How can I further investigate?

3 Masters
5 Data Nodes

All have X-Pack Platinum

Theory.... Is it possible that the node has an index on it that is needed for x-pack and when it goes down it brings the cluster down with it?

Most likely you have your cluster setup incorrectly. If you want help post your elasticsearch.yml for each node here.

Of course if you have Platinum, just contact support. They will probably have you fixed quickly.
