ElasticSearch data loss after host reboot


I've installed elasticsearch-1.7.0 and have created bunch of indices, visualizations & dashboards using kibana-4.1.1-linux-x64. All these were working fine until we re-booted the machine on which elastic-search server was hosted.

After the restart, elastic search server started creating data/elasticsearch/nodes/1 and ignores nodes/0.

I tried the following and it still comes up with empty index/vis/dashboard:

  1. Started the elastic-search server with -Des.node.name=0
  2. Copied nodes/0/indices to nodes/1/indices

How do I get these indices, dashboards back on Kibana?
