适用场景

  • ONTAP 9
  • NFS V3  
  • 网络锁定管理器(NLM)
  • 网络状态监控器(NSM)

问题解答

  • 节点的升级/重新启动相当于 在NFS V3中锁定时发生服务器崩溃、这是 使用NLM和NSM等辅助协议实现的
  • 当服务器在升级/重新启动后准备好再次提供数据时、它需要通知所有先前保持锁定的客户端
  • 然后、由于服务器丢失了有关崩溃前发出的锁定的所有信息、客户端可以回收其所有现有锁定
  • 此通知工作由状态监控器(NSM)使用客户端的回调信息(保存在文件中)通过sm_Notification调用完成
  • 如果SVM无法访问某个 客户端/客户端列表的portmap程序、则EMS日志将显示以下错误消息

    [?] Tue May 05 16:47:27 CEST [Cluster01-01: nblade2: Nblade.CallbackTimedOut:error]: SM NOTIFY: Vserver 11, Vif 1057: PORTMAP program (Program number:100000 Program version:2) on client 10.11.12.10 is not responding.
  • 无需执行任何操作、因为" Nblade.CallbackTimedOut "消息应在重新启动事件发生后大约24小时停止。

    Tue May 05 20:04:12 CEST [Cluster01-01: nblade2: Nblade.CallbackTimedOut:error]: SM NOTIFY: Vserver 11, Vif 1175: PORTMAP program (Program number:100000 Program version:2) on client 10.11.12.10 is not responding.

追加信息

  • NetApp 支持站点—错误在线—系统日志翻译器
  • SVM无法访问 portmap 程序的原因可能有所不同、需要对SVM与报告的客户端之间的网络连接进行故障排除
    • 在某些情况下、客户端可能在发布之前已删除与ONTAP的连接
    • 如果服务器无法再次访问某些客户端、则这些消息应定期(几乎每10分钟一次)显示在EMS中
