please do not use this old annotation for storage class.
use storageClassName in the pvc spec instead.

#> cat storage-class-primaryfs.yml
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1

please do not use beta (also in other places here)
check the helm storage class which is already aligned with it

We are still looking for right usecase to show the RWM functionality with scale. As of now we dont have proper usecase to show this functionality. So for now we will keep these example and if in future we came up with good usecase we will add it.
