``` { "cluster_name": "app_search", "status": "yellow", "timed_out": false, "number_of_nodes": 2, "number_of_data_nodes": 2, "active_primary_shards": 5, "active_shards": 10, "relocating_shards": 0, "initializing_shards": 0, "unassigned_shards": 5, "delayed_unassigned_shards": 0, "number_of_pending_tasks": 0, "number_of_in_flight_fetch": 0 } ``` i tried with below approach 1)my cluster health was red then i have deleted data folder then cluster health became green after that i have created mapping it's turned to yellow, so if i am missing anything please help me out on this. ---

So are you asking for assistance here, or just telling us your cluster is yellow? ---

My guess is that you defined the number of replicas to 2. ---

Thanks for your replay, Yes David , I have define index.number\_of\_replicas:2 is it ok or not ---

So everything is correct here. You have 5 primary shards + 2 copies of each which means 15 shards to allocate. On a 2 nodes cluster, you will end up with - 5 primary shards - 5 replica shards If you add a new node you will allocate: - 5 primary shards - 5 replica shards - 5 replica shards ---

thanks for your response David. if everything seems correct, does this mean cluster health yellow will not make any problem in future ? ---

The question is "why did you change the number of replicas?". I won't keep a yellow cluster in production. If a node stops, you won't be able to index new data because of the quorum. So if you want to have only 2 data nodes, keep number of replicas to 1. But in any case add a 3rd node to avoid split brain issue. Can be a master only node which will act as a tie breaker. ---

Thanks for your response David , I am New to Elastic Search, How can I change cluster health yellow to green is there any way to do that. ---

If you are new to elasticsearch, why did you change the replica settings? Change that. Read: [https://www.elastic.co/guide/en/elasticsearch/reference/2.3/indices-update-settings.html](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/indices-update-settings.html) ---

Hi David, I have 3 server's i need to sync the data of this 3 server's how can i do in elasticsearch(cluster name and index name is same in all server's,in every server i have install elasticsearch separately ) Example:10.141.4.221 is Load Balancing it's have 3 server's (10.141.2.2,10.141.2.3,10.142.2.4) cluster and index name is same in all server's ---
