  • FabricPool

问题描述

BIN1 中卷占用空间的总和值小于在聚合和 Azure 中可以看到的值。 
 
示例:
  • 聚合 Blob 总数:

aggr show-space aggr01

Aggregate : aggr01
Object Store: aggr01_blob
Feature              Used    Used%
-------------------------------- ---------- ------
Referenced Capacity          7.90TB    -
Metadata                 0B    -
Unreclaimed Space           4.13TB    -

Total Physical Used         12.03TB    -

  • 复合容量层已用:

​​​​​​​aggr show -fields physical-used, composite-capacity-tier-used -aggregate aggr01

aggregate   physical-used composite-capacity-tier-used
------------ ------------- ----------------------------
aggr01       169.19TB           12.03TB

  • 使用命令 df -a : 

df -A -composite aggr01

Aggregate      Store kbytes      used   avail
aggr01     aggr01_blob    - 12925697350     -

因此,考虑 到转换,总容量为 12.038 TB 。
 
所有值均相同。

但是 ,如果在volume-blocks-footprint-bin1运行 volume show-footprint 时手动执行返回值之和 ,则获得的值会更小。
