If you are not familiar with the kubectl command, check out my article Getting Started with kubectl.

A persistent volume (PV) is the "physical" volume (such as a hard disk drive or solid state drive) on the host machine (node) that stores your persistent data, whereas a persistent volume claim (PVC) is a reference to a persistent volume, used by a pod.

The kubectl get persistentvolumeclaims command can be used to list the persistent volume claimss that have been created.

~]# kubectl get persistentvolumeclaims
