Orphan Data Node


We lost our master-nodes in our cluster due to a faulty deployment process, and now our data-nodes cant join the new master nodes due to cluster id mismatch.

If we want no data-loss, what are our options?

Which version of Elasticsearch are you on?

Unfortunately if you lost your master nodes then you have already lost data. The master nodes hold information that isn't held elsewhere. Your best bet is to restore from a snapshot.

(It'll be version 7.x, Christian, since earlier versions would erroneously ignore the lost data)
