回答

○階層化データを含む FabricPool フレキシブルボリュームは、再ウォームアップなしで FlexGroup に変換でき、データをパフォーマンス階層に戻すことはできません。

追加情報

最初にデータを再ウォームアップせずに FlexGroup に変換する例:パフォーマンス階層にデータを戻す

1. 次のボリュームは FlexGroup ではありません

::*>volume show -volume myvol -fields is-flexgroup,tiering-policy
vserver volume is-flexgroup tiering-policy
------- ------ ------------ --------------
svm1    myvol false        auto

2. ストレージ階層の現在の設置面積を表示します

 ::> 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. ボリュームを FlexGroup に変換します

::> set advanced

a.最初に check-only オプションを実行します

::*>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.変換を開始します
::*>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. データがパフォーマンス階層に再ウォームアップされていないことを確認します

 ::*> 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%
