在https://kubernetes.io/docs/tutorials/stateful-application/cassandra/中，我们在/application/cassandra/cassandra-statefulset.yaml示例中读取：
x1c 0d1x的数据
因此.我按照以下指示部署了一个nfs-subdir-external-provisioner：https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner/blob/master/charts/nfs-subdir-external-provisioner/README.md#install-multiple-provisioners，指定volume name used inside the pod到nfs.volumeName：

在cassandra-statefulset.yaml中，我设置了volumeMounts as pod的卷`：“k8s-eu-1-worker-1-nfs-v”：

volumeMounts:
    - name: k8s-eu-1-worker-1-nfs-v

我做错了什么？在statefulset.yaml文件中指定VolumeMounts的name的正确方法是什么？
