A status of Pod mounted NFS PV remain as terminating when a node shutdown and restart. A Pod is completely terminated. Deploy a Pod mounted NFS PV Shutdown the node where the Pod is running Wait for 5 min and the Pod status become Restart the node The Pod status is still and the Pod is never terminated completely <detailsPrepare a NFS Server.(I used ) Deploy a Pod mounted NFS PV like this. Shutdown the node where the Pod is running.(In this case ) And the status of node02 becomes . After 5 min later(by default), the Pod status becomes . (The time a Pod becomes status depends on .) Then, restart the node and the status of node02 becomes . But the Pod status is still and the Pod is never terminated completely. It seems that a faild to delete Pod because of trying to unmount a not mounted directory. Force delete Pod.

Reopening, fix had to be reverted due to unit tests requiring root permissions ()
I am terribly sorry... Please wait a moment. I'll try to fix it.
no worries, just get to review the rework, making sure the units tests don't require root permissions
Thank you! Fixed in .
