VolumeClaimTemplates

[TC-robV]

Anyway to get this to work for a VolumeClaimTemplate in a StatefulSet?
I tried the following with no luck. Curious if anyone got it working somehow?

  volumeClaimTemplates:
  - metadata:
      name: storage
      annotations:
        backup.kubernetes.io/deltas: P1D P30D
    spec:
      storageClassName: ssd-retain
      accessModes: [ ReadWriteOnce ]
      resources:
        requests:
          storage: 25Gi
