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.

 
  • vol_fp_moveme 托管在聚合上 aggr2_fptiering-policy 并设置为 autotiering-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 Performance Tier、尚未分层到任何myS3Fabricpool 位置。
myCluster::*>vol show-footprint vol_fp_moveme
Vserver : svm1
Volume  : vol_fp_moveme
Feature                                          Used    Used%
--------------------------------           ----------    -----
Volume Data Footprint                          8.12MB       0%
Footprint in Performance Tier                  9.77MB     100%
Footprint in myS3Fabricpool                       0B       0%
  • WAFL 冷数据报告(CDr)统计信息显示 2001 过期 0 to 2 days 时间为(001 天)的块-预期它将在明天分层:
myCluster::>set adv

  • 卷将移动到另一个FabricPool 聚合 aggr4_fp
myCluster::*>volume move start -vserver svm1 -volume vol_fp_moveme -destination-aggregate aggr4_fp
[Job 1337] Job is queued: Move "vol_fp_moveme" in Vserver "svm1" to aggregate "aggr4_fp". Use the "volume move show -vserver svm1 -volume vol_fp_moveme" command to view the status of this operation.

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       aggr4_fp           auto                  2

myCluster::*>statistics start -sample-id mysample -object wafl_cdr_vol
Statistics collection is being started for sample-id: mysample

myCluster::*>statistics stop -sample-id mysample
Statistics collection is being stopped for sample-id: mysample

myCluster::*>vol show -vserver svm1 -volume vol_fp_moveme -fields name-ordinal
vserver   volume        name-ordinal
--------- ------------- ------------
svm1      vol_fp_moveme       1
 
  • 块温度已重置、分层数据至少需要2天的时间:
myCluster::*>statistics show -sample-id mysample -object wafl_cdr_vol -instance aggr_aggr4_fp_vol_vol_fp_moveme(1) -counter blks_cooled_by_ranges|blks_scanned|blks_days
Object: wafl_cdr_vol
Instance: aggr_aggr4_fp_vol_vol_fp_moveme(1)
