I am using Elasticsearch Version 5.6.8 . I am changing the elasticsearch path data in elasticsearch.yml to a new folder in a new mountpoint . When i restart the elasticsearch service its giving below error [2018-06-13T15:49:36,873][ERROR][o.e.b.Bootstrap] Exception java.lang.IllegalStateException: detected index data in default.path.data [/var/lib/elasticsearch] where there should not be any; check the logs for details I have already done chown elasticsearch:elasticsearch for the new folder ..Why is elasticsearch complaining of index data in default.path.data Please help ---

I assume it's the old one. This error is telling you that you have configured your ES node to use a custom data path, but you also have index data in the default data path (`/var/lib/elasticsearch`). This is almost always a mistake, and if ES starts writing to the new data path, then you will get yourself into a state with diverging indices that probably cannot be recovered correctly. When you create a new (replacement) data path, you need to manually _move_ the data from the old path to the new path. Feel free to keep a copy of the old data somewhere, but don't keep it in the old data path. ---

I came about this but for elasticsearch ..looks like same behaviour ..But my elasticsearch is 5.6.8 ..The blog says its fixed from 5.3 versions ☹ > **[Multi data path bug in Elasticsearch 5.3.0](https://www.elastic.co/blog/multi-data-path-bug-in-elasticsearch-5-3-0)** > > If you use a custom data path with Elasticsearch 5.3.0, you may be subject to a bug which could cause data loss unless properly handled. ---

Please read my reply above. The behaviour you are seeing is intentional. It is not a bug, it is attempting to prevent your data from being corrupted due to bugs or misconfiguration. You can read that message as if it were saying: > You have changed the `path.data` from its default value to another value, but there is still data in the default location. This could be a misconfiguration, or it could be the result of a bug. Please investigate and make sure that your index data in in the correct place before you restart your node. ---
