应用场景

HBlock源卷为luna1，快照为luna1-snapshot，在CSI中创建快照csi-static-snapshot-luna1。

操作步骤

1. 创建VolumeSnapshotContent的配置文件snapshot-content-luna1.yaml。

   apiVersion: snapshot.storage.k8s.io/v1
   kind: VolumeSnapshotContent 
   metadata:
     name: csi-static-snapshot-content1  
   spec:
     deletionPolicy: Delete  
     driver: stor.csi.k8s.io
     source:
       snapshotHandle: cluster1:luna1:luna1-snapshot 
     volumeSnapshotRef:
       name: csi-static-snapshot-luna1  
       namespace: default
   

2. 创建VolumeSnapshot的配置文件snapshot-static-snapshot-luna1.yaml。

   apiVersion: snapshot.storage.k8s.io/v1
   kind: VolumeSnapshot
   metadata:
     name: csi-static-snapshot-luna1
     namespace: default 
   spec:
     source:
       volumeSnapshotContentName: csi-static-snapshot-content1
   

3. 应用VolumeSnapshotContent和VolumeSnapshot的配置文件。

   [root@k8s-master stor-examp]# kubectl apply -f snapshot-content-luna1.yaml
   volumesnapshotcontent.snapshot.storage.k8s.io/csi-static-snapshot-content1 created
   [root@k8s-master stor-examp]# kubectl apply -f snapshot-static-snapshot-luna1.yaml 
   volumesnapshot.snapshot.storage.k8s.io/csi-static-snapshot-luna1 created
   

4. 查看快照。

   [root@k8s-master stor-examp]# kubectl get volumesnapshots
   NAME                        READYTOUSE   SOURCEPVC   SOURCESNAPSHOTCONTENT          RESTORESIZE   SNAPSHOTCLASS   SNAPSHOTCONTENT                CREATIONTIME   AGE
