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 - #3 by dakrone](https://discuss.elastic.co/t/distress-elasticsearch-does-not-start/152288/3) for more details, but here is the quick summary:

1. ELK 541 working fine.
2. Upgraded to ELK640, ES640 and Kibana640 came up fine, Logstash 640 had some issues.
3. Went back to ELK 541 (possibly this was the mistake! ☹ It did not come up. As possibly downgrading is not supported.
4. Came back to ELK 640 - but it wont start now. Possibly corrupted data?

Full error log at [ES640 Fails to start · GitHub](https://gist.github.com/rsmoorthy/132223e7540edc2c73c2827f8ebb732d)

Any help to recover the data is appreciated!!

Please don't post the same thing more than once, it makes it harder for people to help 🙂
