当更改日志使用率超过 20% 时、卷效率（重复数据删除）未完成自动效率策略

适用场景

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

问题描述

• 对于 auto 效率策略和更改日志使用量超过默认阈值20%的卷、卷效率(重复数据删除)操作会运行、但无法完成。
• 更改日志已满20%以上时、应运行自动重复数据删除。
• volume efficiency show 命令可提供 类似于以下内容的输出：

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

• 请注意、未报告任何错误、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。
