为什么 " 卷显示 " 显示的值大于 0 、表示 " 重复数据删除节省的空间 " 、即使未设置卷效率策略?

解答

存储虚拟机( SVM )上使用 ODX 进行副本卸载时,这是预期的行为,因为 ODX 将重复数据删除用作复制过程的一部分。

在这种情况下,“volume efficiency show”命令显示卷效率策略已禁用。

示例:

::> volume efficiency show
Vserver    Volume           State     Status      Progress           Policy
---------- ---------------- --------- ----------- ------------------ ----------
SVM_name   Volume_name      Idle      Idle for 1049:24:04 -        Disabled

但是,“volume show输出”在“重复数据删除节省的空间”中显示的值大于 0 KB 。

示例:

::> volume show -volume vol1
                                     Vserver Name: SVM1
                                      Volume Name: vol1
...
        Volume Contains Shared or Compressed Data: true
                Space Saved by Storage Efficiency: 768KB
           Percentage Saved by Storage Efficiency: 0%
                     Space Saved by Deduplication: 768KB
