title: Does statefulset transfer data if restarted with higher volume?
body: <p>I have a statefulset having <code>2</code> replicas and I want to increase the storage in each of the pods from <code>300GB</code> to <code>3TB</code>. So I edited the statefulset to increase the storage.</p>
  <p>But this doesn't get reflected directly. I plan to do a rollout restart using the command of type:</p>
  <p><code>kubectl rollout restart statefulset my-statefulset</code></p>
  <p>But I am not sure if this will create Pods with fresh volume or if there is an easy way to ensure that it transfers the old data of <code>300GB</code> to the volume of <code>3TB</code>.</p>
  <p>I am using GKE.</p>
