After experiencing slowness in the Kibana UI from the jump from 6.8.9 to 7.7.1, I was told on the forums I should upgrade to 7.8 as that had a number of UI performance improvements. All elasticsearch nodes were upgraded from 7.7.1 -> 7.8.1, and then I updated Kibana to 7.8.1.
Kibana has been sitting at 'Kibana server is not ready' for over an hour now. I've stopped and restarted the service to no avail. In the journalctl log I keep seeing the following repeating:
Aug 05 21:36:09 kibana kibana[7573]: {"type":"log","@timestamp":"2020-08-05T21:36:09Z","tags":["info","savedobjects-service"],"pid":7573,"message":"Detected mapping change in \"properties.namespaces\""}
The upgrade for elasticsearch was missed on the Kibana node unfortunately. Upon the realization, I killed the Kibana service, upgraded elasticsearch and then restarted kibana but it seems the damage has already been done.
How do we get Kibana back up and running?
