将 FlexVol 卷 SnapMirror 关系转换为 FlexGroup 卷 SnapMirror 关系

要在 ONTAP 中将 FlexVol 卷 SnapMirror 关系转换为 FlexGroup 卷 SnapMirror 关系，必须首先转换目标 FlexVol 卷，然后转换源 FlexVol 卷。

1. 验证 SnapMirror 关系是否正常运行：snapmirror show

   仅可转换 XDP 类型的镜像关系。

   示例

   cluster2::> snapmirror show
                                                                          Progress
   Source            Destination Mirror  Relationship   Total             Last
   Path        Type  Path        State   Status         Progress  Healthy Updated
   ----------- ---- ------------ ------- -------------- --------- ------- --------
   vs0:src_dpv DP   vs2:dst_dpv  Snapmirrored
                                         Idle           -         true    - 
   vs0:src_xdp XDP  vs2:dst_xdp  Snapmirrored
                                         Idle           -         true    -
   
2. 验证源卷是否兼容转换过程：
   1. 登录到高级权限模式：set -privilege advanced
   2. 验证转换过程：volume conversion start -vserver vs1 -volume src_vol -check-only true

      转换卷之前，必须纠正所有错误。
3. 将目标 FlexVol 卷转换为 FlexGroup 卷。
   1. 暂停 FlexVol SnapMirror 关系：snapmirror quiesce -destination-path dest_svm:dest_volume

      示例

      cluster2::> snapmirror quiesce -destination-path vs2:dst_xdp
      
   2. 开始转换：volume conversion start -vserver dest_svm -volume dest_volume

      示例

      cluster-1::> volume conversion start -vserver vs2 -volume dst_xdp
       
      Warning: After the volume is converted to a FlexGroup, it will not be possible 
      to change it back to a flexible volume.
      Do you want to continue? {y|n}: y
      
      [Job 510] Job succeeded: SnapMirror destination volume "dst_xdp" has 
      been successfully converted to a FlexGroup volume. 
      You must now convert the relationship's source volume, "vs0:src_xdp", to a FlexGroup. 
      Then, re-establish the SnapMirror relationship using the "snapmirror resync" command.
      
4. 将源 FlexVol 卷转换为 FlexGroup 卷：volume conversion start -vserver src_svm_name -volume src_vol_name

   示例

   cluster-1::> volume conversion start -vserver vs0 -volume src_xdp
    
   Warning: Converting flexible volume "src_xdp" in Vserver "vs0" to a FlexGroup
            will cause the state of all Snapshot copies from the volume to be set
            to "pre-conversion". Pre-conversion Snapshot copies cannot be
            restored.
   Do you want to continue? {y|n}: y
   [Job 57] Job succeeded: success
   
5. 再同步关系：snapmirror resync -destination-path dest_svm_name:dest_volume

   示例

   cluster2::> snapmirror resync -destination-path vs2:dst_xdp
