适用场景

  • ONTAP 9.8及更高版本
  • Kubbernetes集群
  • NetApp Astra三端
  • NFSv3
  • NFSv4.x

问题描述

  • EMS:

kernel: nblade.execsOverLimit:error]: The number of in-flight requests from client with source IP 10.20.30.40 to destination LIF 10.20.30.50 (Vserver 7) is greater than the maximum number of in-flight requests allowed (128). The client might see degraded performance due to request throttling.

注意:  notice 在较新的修补程序版本中、此消息已更改为严重性。这反映了这样一个事实、即此消息可能并不总是值得关注的发生原因。

  • 此消息是正常的、在使用Oracle DNFS客户端时是预期的。它并不表示存在问题。
  • 在NFS客户端(尤其是Linux)的高峰负载期间、可能会出现高延迟或吞吐量突然下降。
  • 性能影响不能归因于通过CLI或监控工具在存储控制器上出现的CPU/内存/磁盘瓶颈

注意: 此消息是在ONTAP 9.8中引入的、但在ONTAP 9.8之前存在限制、因此、需要考虑相同的注意事项
