title: How to resize existing SolrCloud with new shards
body: <p>I've setup a <strong>SolrCloud</strong> structures having 3 shards. Each shard consist of 2 nodes. One is Leader and another is replica. Each solr instance (as node) is running in the separate machine. Now I need to add more machines as my data volume increases. But if I add new node without creating new shard, it'll simply increase more replica of shards. I want to <strong>create more shards with new machines and the data should be distributed among the shards</strong>.</p>
  
  <p>For testing purpose, I created a SolrCloud with one shard (2 nodes). I tried solr <strong>SPLITSHARD</strong> with solr-4.5.1. Finally, I see total 3 shards (<strong>shard1</strong>, <strong>shard1_0</strong> and <strong>shard1_1</strong>) from the admin window. Now it's showing total 6 nodes.</p>
  
  <p>In the background, it has created the following folders under each node.</p>
  
  <p>node1 :</p>
  
  <ol>
  <li>solr/collection1</li>
  <li>solr/collection1_shard1_0_replica1</li>
  <li>solr/collection1_shard1_1_replica1</li>
  </ol>
  
  <p>node2 :</p>
  
  <ol>
  <li>solr/collection1</li>
  <li>solr/collection1_shard1_0_replica2</li>
  <li>solr/collection1_shard1_1_replica2</li>
  </ol>
  
  <p>It means, it created 2 new cores under each instance. But I want to run a single core under each machine.</p>
