ElasticSearch 6.4.0 fails to start with Java IO exception:
org.elasticsearch.ElasticsearchException: java.io.IOException: failed to read [id:305, file:/var/lib/elasticsearch/nodes/0/_state/global-305.st]
Please see Distress: Elasticsearch does not start for more details, but here is the quick summary:
- ELK 541 working fine.
- Upgraded to ELK640, ES640 and Kibana640 came up fine, Logstash 640 had some issues.
- Went back to ELK 541 (possibly this was the mistake! It did not come up. As possibly downgrading is not supported.
- Came back to ELK 640 - but it wont start now. Possibly corrupted data?

Any help to recover the data is appreciated!!
