适用场景

  • ONTAP 9.3 及更高版本
  • 全闪存 FAS (AFF)

问题描述

在 AFF 上、系统会监控具有自动策略的所有卷、并降低卷的优先级、从而减少节省的成本或频繁覆盖。

  • 已取消优先级的卷不再参与自动后台重复数据删除。
  • 已禁用已取消优先级的卷上的更改日志记录,并且卷上的元数据将被截断。

用户可以使用 volume efficiency promote 高级权限级别提供的命令提升已取消优先级的卷,以重新参与自动后台重复数据删除。

  • 运行进行验证

 ::>event log show -node <node_name> -message-name Sis.Volume.Savings.Deprioritized

EMS 示例:
Thu May 02 00:05:38 EDT [node_name: dense_worker: Sis.Volume.Savings.Deprioritized:info]: Auto Dedupe Scheduling on volume vol1(1) deprioritized : low savings (0%%) against minimum (10%%).

  • 运行 volume efficiency show。卷级后台重复数据删除需要按 auto 顺序使用预定义的 AFF 策略 自动运行

::*> volume efficiency show -fields policy


vserver volume policy
