          Hyperdisk volume smaller than 4Gi cannot be created

      Version-Release number of selected component (if applicable):

      How reproducible:

          Always

      Steps to Reproduce:

    2.Create a DV/PVC with volume capacity smaller than 4Gi
    4.PVC gets stuck in Pending, with event:
Warning  ProvisioningFailed    20s (x10 over 5m1s)  pd.csi.storage.gke.io_ahafe-gcp-high-bhhd5-master-2.c.ocpstrat-1278.internal_ee5a8bd3-b1d9-4e9f-837d-73d624d90e91  failed to provision volume with StorageClass "balanced-storage": rpc error: code = InvalidArgument desc = CreateVolume failed: rpc error: code = InvalidArgument desc = CreateVolume failed to create single zonal disk pvc-4b0d2cc9-a677-4d36-9b34-bc14c8650826: failed to insert zonal disk: unknown Insert disk error: googleapi: Error 400: Disk size cannot be smaller than 4 GB for disk type hyperdisk-balanced., badRequest%!v(MISSING)

      Actual results:
