title: What is the difference between"Pod The node had condition: [DiskPressure]" and "The node was low on resource: ephemeral-storage"
body: <p>When the pod is Evicted by disk issue, I found there are two reasons:</p>
  <ol>
  <li>The node had condition: <code>[DiskPressure]</code></li>
  <li>The node was low on resource: ephemeral-storage. Container NAME was using 16658224Ki, which exceeds its request of 0.</li>
  </ol>
  <p>I found <a href="https://kubernetes.io/docs/concepts/scheduling-eviction/node-pressure-eviction/#node-conditions" rel="nofollow noreferrer">Node conditions</a> for <code>DiskPressure</code>.</p>
  <p>What is the difference?</p>
