适用场景

  • ONTAP 9
  • NetApp 卷加密 (NetApp Volume Encryption, NVE)
  • NetApp 聚合加密( NAE )

问题解答

1. 将权限级别设置为高级:

::> set adv

2.  cross-volume-background-dedupe 在所有NAE卷上启用:

::*> volume efficiency modify -vserver <vserver_name> -volume <vol_name> -cross-volume-background-dedupe true

3.  cross-volume-inline-dedupe 在所有NAE卷上启用:

::*> volume efficiency modify -vserver <vserver_name> -volume <vol_name> -cross-volume-inline-dedupe true

4.  volume-level background dedupe 在所有NAE卷上运行、并等待所有卷完成:

::*> volume efficiency start -volume <vol_name> -vserver <vserver_name> -scan-old-data true -dedupe true

::*> volume efficiency show

5. 运行 cross-volume background dedupe:

::*> storage aggregate efficiency cross-volume-dedupe start -aggregate <aggr_name> -scan-old-data true and storage aggregate efficiency cross-volume-dedupe show
