PV gets stuck "timeout expired waiting for volumes to attach/mount for pod" on Dedicated
Issue
- When we scaled down and up the pods, the pods stopped working. Event logs are below:

- I heard from Red Hat that it was is an issue on OCP 3.3 and should not scale down/up quickly. But when I waited 10 seconds, and then scaled them back from 0 to 1. The issue happened again.
