Verified on v3.4.1.27 Steps: 1. Create NFS PV and create an app using the jenkins-persistent template. 2. Once the jenkins pod is running, bring down the node by stopping it's node service. 3. The pod will be redeployed to another schedulable node. 4. After the pod is deployed to another node, bring back the stopped node service. 5. On the original node, verify the jenkins pod volume is successfully unmounted, the pod directory is removed while all data in the persistent volume are still there.
