kubernetes: Pod with NFS volume attached cannot be terminated

Is this a BUG REPORT or FEATURE REQUEST?: /kind bug

What happened: When trying to delete a nfs-volume pod it gets stuck in “Terminating” state.

What you expected to happen: The pod should be deleted

How to reproduce it (as minimally and precisely as possible):

1. Create one namespace called: e2e-tests-kubelet-bugtest1
2. Create a second namespace called: e2e-tests-kubelet-bugtest2
3. Create a new nfs-server pod using the nfs-server.yaml
4. Add the ip of the nfs-server pod to the pod-nfs-vol.yaml
5. Create a second pod using the pod-nfs-volume.yaml
6. Delete the nfs-server pod without stopping the server
7. Try to delete pod-nfs-volume pod.

Anything else we need to know?: Recreating this using YAML files is easier (and possibly more accurate):
