title: How to identify the storage space left in a persistent volume claim?
body: <p>I have a Kubernetes cluster on Google Cloud Platform. It has a persistent Volume Claim with a Capacity of 1GB. The persistent volume claim is bound to many deployments. </p>
  
  <p>I would like to identify the space left in the persistent Volume Claim in order to know if 1GB is sufficient for my application. </p>
  
  <p>I have used the command "kubectl get pv" but this does not show the storage space left.</p>
