适用于

  • Cloud Volumes ONTAP
  • AWS 调解器

问题解答

集群功能:

  • 集群将继续运行,但将以降级状态运行,直到调解节点恢复联机。
  • 调解器主要负责管理 HA 配置中的故障转移操作。如果调解器不可用,则在重新启动期间不会发生节点之间的自动故障转移。

无自动故障转移:

  • 如果没有中介,在发生节点故障时,HA节点之间不会发生自动故障转移。这意味着如果在重新启动窗口期间发生节点故障,则可能需要手动干预才能还原服务。

已降级状态:

  •  当介质离线时,HA 对以降级模式运行,这意味着介质提供的冗余暂时丢失。但是,集群的主数据服务操作应保持不受影响,除非其中一个 HA 节点同时发生故障。

重启后检查:

  • 重新启动后,检查介体是否恢复联机,验证其状态,并确认 HA 对已恢复正常工作状态。
