Adding one more DATA node and increasing number of shards to four from three

Elastic Stack Elasticsearch

Hey,

My current cluster architecture is as follows:

  • Three master nodes
  • Three data nodes
  • Two ingest nodes

And I am using X-Pack on the current cluster. Plus, here is my default template for shards and replicas strategy.

{
  "default_template": {
    "order": 0,
    "index_patterns": [
      "*"
    ],
    "settings": {
      "index": {
        "number_of_shards": "3",
        "number_of_replicas": "1"
      }
    },
    "mappings": {},
    "aliases": {}
  }
}

Now I want to add a new DATA node to the cluster in order to distribute the load among more nodes and speed up the lookup time for users.

My new cluster will be as follows:

  • Three master nodes
  • Four data nodes
  • Two ingest nodes

Can you please tell me how can I add the new DATA node? References? Best Practices? Step by step guide?

Thank you.
