一、文件共享类型快照：

### --- 操作步骤和块存储类型无区别，可以参考：

~~~     https://rook.io/docs/rook/v1.5/ceph-csi-snapshot.html#cephfs-snapshots

---

二、PVC克隆

#1、进出创建目录
[root@k8s-master01 rbd]# pwd
/root/rook/cluster/examples/kubernetes/ceph/csi/rbd

#2、修改clone的pvc文件
[root@k8s-master01 rbd]# cat pvc-clone.yaml 
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: rbd-pvc-clone
spec:
  storageClassName: rook-ceph-block
  dataSource:
    name: mysql-pv-claim
    kind: PersistentVolumeClaim
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 30Gi

### --- 创建克隆PVC
~~~     需要注意的是pvc-clone.yaml的dataSource的name是被克隆的pvc名称，
~~~     在此是mysql-pv-claim，storageClassName为新建pvc的storageClass名称，
~~~     storage不能小于之前pvc的大小。

[root@k8s-master01 rbd]# kubectl create -f pvc-clone.yaml 
persistentvolumeclaim/rbd-pvc-clone created
[root@k8s-master01 rbd]# kubectl get pvc
NAME             STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS      AGE
