  • "Extended Compressed Data "字段指示卷上是否存在扩展压缩数据。
  • 当应用程序IO大小配置为8K的自适应数据压缩和数据缩减均已启用时、此字段将显示`true `。

追加信息

要启用扩展压缩数据、请确保已正确配置自适应数据压缩和数据缩减。

  • 使用以下命令检查卷的当前效率设置：

::> volume efficiency show -instance

查找字段`Storage Efficiency Mode `和`Data Compaction `。

  • 使用以下命令启用自适应数据压缩和数据缩减：

::> volume efficiency modify -vserver <vserver_name> -volume <volume_name> -storage-efficiency-mode efficient

::> volume efficiency modify -vserver <vserver_name> -volume <volume_name> -data-compaction true
