Hello Team-
We have tried to update our current ELK from 7.4.0 to 7.16.0, after creating a snapshot from Kibana. However, we were unable to do so. So, we have uninstalled Elasticsearch from all our 6 nodes (which were in cluster) and also deleted data as our file system was 99% utilised.
We were able to bring back up the 6 nodes clusters after we have re-installed Elasticsearch again. But we were unable to see the snapshot in Kibana we created in prior. We are constantly getting the below errors.
nested: RepositoryVerificationException[[backup] a file written by master to the store [/data/repo/elasticsearch_backup] cannot be accessed on the node [{node_name}{Sy6-OHfSTYyYsoWUOKpDfA}{Kjil15LmREC97v558KLzCw}{node_name}{node_name:9300}{cdfhilmrstw}{ml.machine_memory=33566654464, xpack.installed=true, transform.node=true, ml.max_open_jobs=512, ml.max_jvm_size=1073741824}].

Can anyone help me on the same?
