in the past I had one elasticsearch and today I created another node the cluster created. when I run GET /\_cat/health?v I got status YELLOW. How I will make the status GREEN ---

Add more nodes or decrease the number of replicas ---

Hi! I think some terms need to be defined or redefined: A node is an instance of Elasticsearch. A cluster is a collection of one or more node. In your case I believe you created a new index. An index by default is created with 5 primary shards and one replica for every one of those shard. If you have only one node, your replicas cannot be allocated, resulting in a yellow cluster. As David says the solution would be to set your number of replica to zero or to add one more node. ---

Thank you, I am using the default shards and replica numbers (5 shareds and 1 replica) What is the equation of replica with number of nodes?? ---

A primary and a replica (of the same shard) cannot be allocated to the same node (it would be useless). Like often when it comes to architecture: it will depend on different factors like how many server do you expect to fail and so on. ---

To allocate replicas, you need more than one node. Replicas are not going to be allocated on the same node as primaries as it is pretty much useless. ---
