func FixupCRs ¶

func FixupCRs(config *restclient.Config, namespace string, lhClient *lhclientset.Clientset) (err error)

FixupCRs initialize the old CR spec which is with the `null` field. Since start from longhorn.io/v1beta2, we introduce the CRD structural schema. However, for the Kubernetes < 1.20, there is an issue that it does not allow the `null` field because of the CRD validation failure.
