适用场景

ONTAP 9

问题描述

  • 对于配置了QoS_Min的所有卷、客户报告客户端上出现"NFS未响应"错误。
  • 延迟细分可从延迟中心查看:NBlade /网络处理。

qos statistics volume latency show

  • 发现大量NFS卷和Giveup被从QoS中逐出
  • 倒带是Nblade中使用的一种机制、用于延迟并重试操作。在重试特定次数或时间后、操作"Givetion"。

::*> statistics start -object rw_ctx -counter nfs_rewinds|nfs_giveups|qos_rewinds|qos_giveups|total_rewinds -sample-id <sample-name>

::*> statistics show -sample-id <sample-name>
