We have created an Elastic Search ECK instance in a Kubernetes cluster. We modified the volume from 1Ti to 2Ti. Now we want to make additional configurations. But, the elastic-operator instance is not recognizing the new volume, and giving the error:
denied the request: Elasticsearch.elasticsearch.k8s.elastic.co "elasticsearch" is invalid: spec.nodeSet.volumeClaimTemplates: Invalid value: v1.PersistentVolumeClaim(nil): Volume claim templates cannot be modified
We have huge volume of data already indexed into the nodes. We want to make modifications to the Elastic search, but we don't want it to impact the existing pvc's. Can this be done? if any guidance on such a scenario will be good.
