Doc Type: Bug Fix
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. Consequence: Data on the PVs are deleted. Fix: Cleaning up Pods on the nodes doesn't delete data on PVs. Result: Data on the PVs are no longer deleted during Pods cleanup.

Comment 5 Jianwei Hou 2017-05-31 10:05:57 UTC 
Verified on openshift v3.2.1.31
kubernetes v1.2.0-36-g4a3f9c5
etcd 2.2.5

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.
