Hello! I'm playing around with Harvester, rancher, and longhorn. I have two storage classes defined in Harvester - ssd, and hdd. When I'm creating an RKE cluster with Rancher in Harvester, there's no option to select which storage class to use anywhere that I can find. The storage class being selected for the node disk is the hdd class, and that is not what I want. How do I select a storage class for my node disk in this scenario?
