<p>What is the difference between persistent volume (PV) and persistent volume claim (PVC) in Kubernetes/ Openshift by referring to documentation?</p>

<p>What is the difference between both in simple terms?</p>

<p>From the <a href="https://docs.openshift.org/latest/architecture/additional_concepts/storage.html#lifecycle-of-a-volume-and-claim" rel="noreferrer">docs</a></p>

<blockquote>
  <p>PVs are resources in the cluster. PVCs are requests for those resources and also act as claim checks to the resource.</p>
</blockquote>

<p>So a persistent volume (PV) is the "physical" volume on the host machine that stores your persistent data. A persistent volume claim (PVC) is a <em>request</em> for the platform to create a PV for you, and you attach PVs to your pods via a PVC.</p>

<p>Something akin to</p>

<pre><code>Pod -&gt; PVC -&gt; PV -&gt; Host machine
</code></pre>
