适用场景

  • ONTAP 9
  • 2 个以上节点集群

问题描述

  • 在双节点集群中,集群 HA 可确保一个节点发生故障不会使整个集群无法工作。

警告: 如果使用 -inhibit-takeover true 参数暂停或重新启动双节点集群中的节点而不进行接管、 则两个节点都将停止提供数据 、除非您更改特定配置设置。

  • 如果在禁用集群HA和移动Epsilon之前尝试重新启动或暂停节点、ONTAP将向您发出警告

::> sytem node reboot -node <node_name> -inhibit-takeover true
Warning: Rebooting or halting node "cluster1-01" in an HA-enabled cluster with takeover inhibited might result in a data serving failure and client disruption. To ensure
continuity of service, do the following before rebooting or halting the node. Disable cluster HA using the command: "cluster ha modify -configured false".
To transfer epsilon to the partner node, use the following commands (privilege:advanced):
 cluster modify -epsilon false -node <local-node>
 cluster modify -epsilon true -node <partner-node>
Do you want to continue? {y|n}:
