| Doc Text: |
Cause: During cluster issues, node left mounts on the nodes referring to Persistent Storage, these mounts removed all the data from the PV.

Verified on v3.5.5.18 Steps: 1. Set up cluster with 1 master, 2 nodes. 2. Create NFS PV and create an app using the jenkins-persistent template. 3. Once the jenkins pod is running, bring down the node which jenkins' pod resides on by stopping it's node service. 4. The pod will be redeployed to another schedulable node(the mount path will exist on both nodes). 5. After the pod is deployed to another node, bring back the stopped node service. 6. 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.
