title: how to delete nodes from redis cluster?
body: <p>I google it and found two solution:</p>
  <ol>
  <li><p><code>CLUSTER FORGET</code> (<a href="http://redis.io/commands/cluster-forget" rel="nofollow noreferrer">http://redis.io/commands/cluster-forget</a>)</p>
  </li>
  <li><p><code>redis-trib.rb del-node</code></p>
  </li>
  </ol>
  <p>I think <code>CLUSTER FORGET</code>&quot; is the right way to do.</p>
  <p>But I really want to know the details about <code>redis-trib.rb del-node</code>.</p>
  <p>Can someone explain the difference between them?</p>
