Failed Openshift node doesn't detach ScaleIO volumes?

11/25/2018

I am using kubernetes.io/scaleio provisioner with Openshift Container Platform 3.9. When I manually shutdown a node, it doesn't detach the volumes attached to the node's assigned pods. As a result, the new pods unable to mount those volumes on another node (ScaleIO is limited for ReadWriteOnce)

Symptom: The new pod is stuck in "Container Creating" status and the events shows the following: Failed Mount - MountVolume.SetUp failed for volume "k8svol-xxxxxxx": Only single SDC may be mapped to this volume at a time

Has anyone encountered this issue? Any solutions?
