适用场景

  • ONTAP

客户可以通过各种形式体验此问题描述: 

  • Shell命令(如 dfls 和) umount 定向到NFS装载点、此命令会无限期挂起、并且永远无法完成运行。
    • 在网络维护、 防火墙维护或重新启动客户端主机之后、可能会发生这种情况
  • 发生网络事件(例如、SVMDR转换到新DNS服务器)、留下陈旧的NFS挂载
  • Linux主机随机出现NFS陈旧挂载
  • 在数据包跟踪中、ONTAP从已建立会话的客户端获取TCP sin数据包。
  • 客户端错误消息 "Server (server-name) not responding, still trying"
