title: Reduce kubernetes Persistent Volumes
body: <p>I am using multiple apps on kubernetes and all are configured with <code>pd-ssd</code> volume. Some deployments are running on big volume with less data. So i wanted to reduce that volume of the pods. I have worked with increase volumen and it was worked. But i can't reduce the space of the volume.</p>
  
  <p>Steps i did. Current size is 100Gi, I want to resize it to 30Gi.</p>
  
  <ol>
  <li>Scaling down the application and pod.</li>
  <li>edit pvc to reduce the size of volume.</li>
  </ol>
  
  <pre><code>k edit pvc my-pvc
  </code></pre>
  
  <p>I got the following error when I save the changes.</p>
  
  <blockquote>
    <p>error: persistentvolumeclaims "my-pvc" is invalid
    A copy of your changes has been stored to "/tmp/kubectl-edit-4ivk1.yaml"
    error: Edit cancelled, no valid changes were saved.</p>
  </blockquote>
  
  <p>But i can not able to save the changes for reduce volume size.</p>
