title: Elasticsearch - Adding node without replication?
body: <p>I have a master/data Elasticsearch node. It has now reached 90% capacity and I need to provision additional space to continue adding more data.</p>
  
  <p>I have created a new server with 700gb disk space, installed ES &amp; Kibana, and now wish for this second server to provide additional space to / work with the master node.</p>
  
  <p><strong>My problem:</strong></p>
  
  <p>As it says on the <a href="https://www.elastic.co/guide/en/elasticsearch/reference/current/add-elasticsearch-nodes.html" rel="nofollow noreferrer">ES website</a>:</p>
  
  <blockquote>
    <p>When you add more nodes to a cluster, it automatically allocates
    replica shards.</p>
  </blockquote>
  
  <p>My issue is that I do not wish to replicate the data from the master node, but instead just provide additional space using this second server which can then be queried by the master node.</p>
  
  <p><strong>My question:</strong></p>
  
  <p>What is the best way to achieve this? Is adding a node the incorrect thing to do here?</p>
