I am working up a system with elasticsearch 5.6.2, I did a rolling update to elasticsearch 6.1.3 but something went wrong with the existing applications, so i reverted back to v5.6.2. The Issue I am facing is, my cluster has formed but the status is RED and when I check the status of any shard from any index, below is the json:
@dadoonet I placed my old data node into the cluster and pulled out the new data node. but still the shards remain unassigned. can this be an issue of the segments.gen file? if so, where can I find it?
