title: Re-use PersistentVolume after re-installing a helm deployment
body: <p>When I <code>helm delete &lt;deploymentname&gt;</code> a deployment its PVs and PVCs are deleted as well. How can I avoid the actual data in the PVs from being deleted and be able to reclaim those PVs when I <code>helm install &lt;deploymentname&gt;</code> again?</p>
  
  <p>I am using <code>helm upgrade</code> regularly but it makes me very uncomfortable if all it takes to delete all data is a helm delete (even without --purge option it removes all PVs) </p>
