适用场景

  • ONTAP 9.12.1
  • 集群会话管理器(CSM)
  • 集群对等策略

问题描述

升级到9.12.1后:
  • 在上次交还期间 storage failover show 、输出中的状态将保持 waiting for partner lock synchronization 很长时间。
  • SAN连接可能是间歇性的
  • 如果所有NAS客户端通过LIF访问的数据所在节点与分配了寻址卷的节点不同、则它们将无法访问数据。
  • NFS showmount 在一个节点上使用数据LIF、而在另一个节点上使用Vserver根卷超时。
  • NFS使用数据LIF在一个节点上挂载、 junction-path 并指向另一节点上的卷失败/超时。
  • 输出 event log show 表示跨节点通信不良和CSM错误、例如:
