We have the following configuration:
2x Elastic Master+Data Nodes (Live data centre)
1x Elastic Voting node (DR data centre)
2x Kibana Nodes (live data centre)
2x Logstash Nodes
If I turn off any of the master+data nodes, the remaining cluster function and recovers to a healthy state when I turn it back on, however if I turn off the voting node, Kibana no longer works (times out) until I re-start the elasticsearch voting node. It does seem that the elasticsearch cluster seem to be functioning as normal (ingesting data from logstash), but the Kibana UI is not available.
Is this expected behaviour, let me know if I need to post any configs?
