Issue: Elasticsearch cluster upgrade stuck.

 

Findings:

We can see pod elasticsearch-cdm-tnwarhmo-1 is on the latest image and elasticsearch-cdm-tnwarhmo-2 and elasticsearch-cdm-tnwarhmo-3 are on the old image.

Verified the latest image by installing the test logging cluster.

 

Elasticsearch operator logs.

Pod 'elasticsearch-cdm-tnwarhmo-1' is already restarted and is up and running. I am wondering why the operator is stuck at 'timed out waiting for node to rollout'.

 

I tried to replicate this issue in the test cluster but the upgrade was completed successfully.
