适用场景

  • ONTAP 9.8 及更高版本
  • Kubernetes 集群
  • NetApp Astra Trident
  • 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

  • 在NFS客户端的高峰负载期间、可能会观察到高延迟或吞吐量突然下降
  • Oracle数据库和其他数据库可能会报告 数据库提交的等待时间较长
  • 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
