在卷移动过程中块温度是否持久？
适用场景
- ONTAP 9
- FabricPool
- 分层
问题解答
否、块温度存储在聚合元数据中、并在将卷移动到另一个聚合时重置。
追加信息
- 配置了两个FabricPool 聚合：
myCluster::*>aggr object-store show
Aggregate Object Store Name Availability Mirror Type
-------------- ----------------- ------------- -----------
aggr2_fp svm-s3-DST available primary
aggr4_fp svm-s3-DST available primary
2 entries were displayed.- 卷
vol_fp_moveme托管在聚合上aggr2_fp、tiering-policy并设置为auto和tiering-minimum-cooling-days2。数据在至少48小时内未被读取后、将分层到配置的云层：
myCluster::*>vol show vol_fp_moveme -fields tiering-minimum-cooling-days, tiering-policy, aggregate
vserver volume aggregate tiering-policy tiering-minimum-cooling-days
--------- ------------- --------- -------------- ----------------------------
svm1 vol_fp_moveme aggr2_fp auto 2- 目前、所有数据都位于中
