适用场景

  • NetApp SolidFire 存储节点
  • NetApp H系列存储节点
  • NetApp Element操作系统、错误日志中仅显示以下示例故障条件:

问题解答

  • 虽然对上述标题的理解各不相同、但在逻辑上将分区和块驱动器从集群中退出一段意外的长时间并不是最佳实践方法。
  • 上述情况 会导致节点不共享集群的工作负载、因此、如果集群中的另一个节点发生故障或脱机、则会减少冗余。
  • 如果只有一个分区驱动器在一段时间内保持可用状态、则会在集群上产生额外的工作负载、因为 节点上数据的所有主iSCSI会话都将重定向到集群中的其他节点。 
  • 如果只有所有块驱动器在一段时间内保持可用状态、则唯一真正的影响就是丢失可用空间。
  • 如果节点只有此故障情况、我们强烈建议客户通过集群UI继续将驱动器添加回集群、以使节点恢复正常运行状态。
