title: Is there an efficient way to check the usage for PV/PVC in Kubernetes
body: <p>For example, I have 50 Gib PV/PVC and grant to one Pod, I just want to check usage of the storage</p>
  
  <p>The way I am just following is to set up a <strong>busybox</strong> pod with mounting the same PVC, then exec into the <strong>busybox</strong> to run <code>df -h</code> to check the storage.</p>
  
  <p>I just want to know if there is an efficient way to do the same thing.</p>
