是否可以在不重新恢复分层数据的情况下将 FlexVol 转换为 FlexGroup ？
适用场景
- ONTAP 9
- FlexGroup
- FabricPool
问题解答
是包含分层数据的 FabricPool 灵活卷可以转换为 FlexGroup ，而无需将数据重新加热到性能层。
追加信息
转换为 FlexGroup 而不先将数据重新加热回性能层的示例
1. 以下卷不是 FlexGroup
::*>volume show -volume myvol -fields is-flexgroup,tiering-policy
vserver volume is-flexgroup tiering-policy
------- ------ ------------ --------------
svm1 myvol false auto
2. 查看存储层的当前占用空间
::> volume show-footprint myvol Vserver : svm1 Volume : myvol Feature Used Used% -------------------------------- ---------- ----- Volume Data Footprint 14.09GB 0% Footprint in Performance Tier 268.5MB 2% Footprint in <your storage Tier> 13.84GB 98% Volume Guarantee 0B 0% Flexible Volume Metadata 683.9MB 0% Deduplication 61.40MB 0% Cross Volume Deduplication 143.0MB 0% Delayed Frees 6.09MB 0% Total Footprint 14.97GB 0%
3. 我们现在将卷转换为 FlexGroup
::> set advanced

a.请先运行仅检查选项
::*>volume conversion start -volume myvol -foreground true -check-only true
Conversion of volume "myvol" in Vserver "svm1" to a FlexGroup can proceed with the following warnings:
* After the volume is converted to a FlexGroup, it will not be possible to change it back to a flexible volume.
b.开始转换
::*>volume conversion start -volume myvol -foreground true
Warning: After the volume is converted to a FlexGroup, it will not be possible to change it back to a flexible volume.

4. 确认数据未重新恢复到性能层
::*> volume show -volume myvol -fields is-flexgroup,tiering-policy vserver volume is-flexgroup tiering-policy ------- ------ ------------ -------------- svm1 myvol true auto
::*> volume show-footprint myvol__0001 Vserver : svm1 Volume : myvol__0001 Feature Used Used% -------------------------------- ---------- ----- Volume Data Footprint 14.15GB 0% Footprint in Performance Tier 276.7MB 2% Footprint in sgws01 13.84GB 98% Volume Guarantee 0B 0% Flexible Volume Metadata 683.9MB 0% Deduplication 61.40MB 0% Cross Volume Deduplication 143.0MB 0% Delayed Frees 12.92MB 0% Total Footprint 15.03GB 0%
