  • 檢查雲端授權
    • 是否已達到授權容量？
       
Capacity licenses:
##   Feature              Shelf Model   Capacity     Mode        Expiration Date
--   ------------------   -----------   ----------   ---------   ---------------
1    CLOUDTIER-CAPACITY   n/a           136.42 TiB   permanent   n/a
--   ------------------   -----------   ----------   ---------   ---------------
  • 檢查組態
    • 是否為 mtree 列出的正確雲端單元
    • 必須在 DD 中正確設定雲端單元。 
    • 備份應用程式無法修改在 DD 中設定的目標單位。
sysadmin@dd4500# data-movement policy show
Mtree                          Target(Tier/Unit Name)    Policy           Value      
-----------------              ----------------------                 ---------        -----------
/data/col1/mtree1   Cloud/cloudunit1               age-range   14-100 days 
-----------------              ----------------------                 ---------        -----------
  • 檢查資料移動狀態
sysadmin@dd4500 # data-movement status
Data-movement to cloud tier:
----------------------------
Data-movement is initializing..
Data-movement recall:
---------------------
No recall operations found.
  • 檢查雲端清理狀態
    • 雲端清理和資料移動無法同時執行
sysadmin@dd4500# cloud clean status
Previous cloud tier cleaning attempt was unsuccessful.
 Failure reason:
cloud unit "cloudunit2" did not have sufficient cleanable data.
Cloud tier cleaning finished at 2017/03/15 12:16:06.
  • 檢查記錄
Fmig = File migration
  • ddfs.info 日誌中搜索數據移動條目。 
  • 在資料移動前後的記錄中搜尋「Fmig」，並檢查檔案遷移動作的順序。
