适用场景

  • ONTAP 9
  • Azure负载平衡器
  • Cloud Volumes ONTAP

问题描述

挂载CIFS共享  Azure Load Balancer 有时会导致频繁出现拒绝访问问题。
  • 如果尝试  从Linux客户端挂载CIFS共享: 
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
  • 数据包跟踪显示:
  • 由于密码错误、大量会话设置请求失败

13347 2023-09-28 15:18:25.445511 10.x.x.xxx 10.y.y.yyy SMB2 442 0 Session Setup Request, NTLMSSP_AUTH, User: \xxxyy

  • 一段时间后、所有CIFS会话设置请求都会直接由ONTAP融合在一起。

  • Secd日志记录错误:
