default-scheduler running PreBind plu

看openebs-localpv-provisioner 和kube-scheduler-minikube 和kube-controller-manager-minikube的报错信息，就发现了问题

volumeClaimTemplates:
    - metadata:
        name: proxysql-data
      spec:
        accessModes:
          - ReadWriteMany  ## 就是这里了 不能用ReadWriteMany只能用ReadWriteOnce
        resources:
          requests:
            storage: 1Gi
        storageClassName: sc-file-hdd
        volumeMode: Filesystem

解决
ReadWriteMany：volumn能被多个容器访问
ReadWriteOnce：volumn只能被一个容器访问
很好理解，statefulset本来就是有状态的数据，必须只能被每一个被一个容器访问

    - metadata:
        name: proxysql-data
      spec:
        accessModes:
          - ReadWriteOnce  # 这里改成ReadWriteOnce
        resources:
          requests:
            storage: 1Gi
        storageClassName: sc-file-hdd
