Hi I'm using localhost so far and if I'm planning to create a cluster later and if I enable network.host and cluster settings, will I lose my data as ES points to localhost:9200 so far?? Regards Ram ---

i created an index using localhost:9200, but when I change network.host and add it to cluster, im not finding that index in kibana ---

I added below node.name: "es-node-1" #define node 1 as master-eligible: node.master: true #define nodes 2 and 3 as data nodes: node.data: true #enter the private IP and port of your node: network.host: 172.11.61.27 http.port: 9200 discovery.zen.ping.unicast.hosts: cluster.initial\_master\_nodes: in all the nodes Also I changed Kibana to point to [http://ip:9200](http://ip:9200) Initially all three cluster nodes with same index called "dashboard-0001". After that I created cluster with these three nodes. After that I dont find dashboard-0001 in kibana ---

Right, so you're doing a bit more than just changing loopback 😉 > [@RAM\_NATHAN](#): > > Initially all three cluster nodes with same index called "dashboard-0001". After that I created cluster with these three nodes. After that I dont find dashboard-0001 in kibana Yes that won't work, because when you join the nodes together they won't know which index they should be using. Why are you creating it on each of the 3 nodes? You should create the cluster with all your nodes, then the indices. ---

> [@RAM\_NATHAN](#): > > cluster.initial\_master\_nodes: Thanks for the reply. Please confirm below will work Initially I have single node points to loop back address. I create an index dashboard-0001 there and later I create two nodes and create a cluster all together. Last two nodes doesnt have index. Now I will not lose my dashboard-0001 data. Correct? ---
