适用场景

  • ONTAP 9.9-9.9
  • 具有 CIFS 工作负载的 FlexGroup
  • 具有CIFS工作负载的FlexVol
  • 多协议FlexGroup 中的NFS (通过CIFS和NFS访问)
  • 更改通知

问题描述

  • CIFS 延迟增加,通常用于写入操作,但也包括创建,设置,打开,关闭
  • 的输出 qos statistics volume latency showdata 将在列中显示大部分延迟
  • VDI环境中托管的用户报告、从FlexVol迁移到FlexGroup后、访问速度立即变慢。 
  • 如果读取或写入多个目录,则一个成分卷上的延迟可能会稳定,或者成分卷之间的延迟会快速连续发生变化
