适用于

  • ONTAP
  • 将效率策略设置为的卷 auto
  • 重复数据删除更改日志的默认阈值为 20%

问题

卷效率(重复数据删除)操作在auto效率策略和更改日志使用率超过默认阈值 20% 的卷上运行但未完成。

一旦更改日志已满 20% 以上、就应运行自动重复数据删除。

volume efficiency show命令提供的输出类似于以下内容:

Cluster01::> volume efficiency show -vserver svm1 -volume vol1 -instance

                   Vserver Name: svm1
                    Volume Name: vol1
                    Volume Path: /vol/vol1
                       State: Enabled

请注意,没有报告任何错误、更改日志使用率为 91% 、操作执行频率非常高、但不执行任何操作。
