I'm running Logstash with Redis, Kibana, and Elasticsearch. All is working well. But when I look in the configured location for data, as set in the elasticsearch.yml file I see nothing. The directory is empty. But I can see my data in Kibana and view it in Redis. So where is Elasticsearch hiding it? My config setting is: path.data: /var/lib/elasticsearch ...which is empty. As I understand it Elasticsearch relies on Lucene which I thought stored data in flat files. If this is the case where are these files? I need to know this so I can adequately plan storage.

I'm new to Elasticsearch and recently started playing around with version 1.0.1. Just saw your question and noticed that the data files at /data//nodes/0/indices//0/index/segment\_1 Note that lucene data is stored in segments.

Hi Marcus, You can find out where the data is by calling the nodes stats api and looking a the fs.data section. Assuming you are running 1.0 this will be: curl -XGET "[http://localhost:9200/\_nodes/stats/fs](http://localhost:9200/_nodes/stats/fs)" And yes, ES stores the data in lucene.
