I'm trying to get a Persisten Volume Claim on GKE and to my understanding using either the standard storage class or the proposed fast storage class I should get a disk provisioned, however I've been waiting for 30 minutes and no disk is being provisioned

my storage classes are the ones in the documentation

More over, I tried both approaches

with the faster class

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: postgres-pv-claim2
  labels:
    app: postgres
spec:
  storageClassName: faster
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 30Gi

and standard

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: postgres-pv-claim-slow
  labels:
    app: postgres
spec:
  storageClassName: standard
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 30Gi

It's been so long that I don't think the volumes are getting provisioned automatically, what could I be missing?
