适用于

  • ONTAP 9
  • FabricPool

问题描述

  • 在设置 cloud-retrieval-policypromote tiering-policynone 之后,手动触发了分层扫描程序
  • 期望从云层删除所有数据并将其提升回性能层
  • volume show-footprint 似乎已确认任何卷中的任何数据当前都不再位于云层中:

DATA_VOL_03
    Feature                            Used     Used%
    ---------------------------------------------    -------------   -----
    Volume Data Footprint                  7.54TB     25%
    Footprint in Performance Tier               7.73TB    102%
    Flexible Volume Metadata                 46.6GB     0%
    Deduplication Metadata                  45.3GB     0%
    Deduplication                       45.3GB     0%
    Delayed Frees                      61.0GB     0%
 
  • aggregate show-space 仍然显示云层中的引用和未引用对象:
Aggregate: AGGR1
cloud_bucket_01

    Feature                           Used    Used%
    ---------------------------------------------    -------------   -----
    Logical Used                       56.4MB    -
    Logical Referenced Capacity               2.79MB     -
    Logical Unreferenced Capacity              53.6MB    -
    Space Saved by Storage Efficiency             148KB    -

    Total Physical Used                   56.3MB    -
  • 这里的假设是分层块占用的空间小于卷大小的 1%,因此 ONTAP 根本不会在 volume show-space 中报告
