适用场景

  • Cloud Volumes ONTAP ( CVO )
  • CIFS

问题解答

  • 客户端正在连接到与本地数据 LIF 绑定的端口上的 CIFS 共享,而不是连接到浮动 IP 数据 LIF 。
  • 示例显示了与本地数据 LIF10.251.164.124 上的端口 445 的连接,而不是浮动数据 IP 10.253.0.2 (未显示):
Node01:
Local Address                                 Foreign Address                              (state)
10.251.164.124. 445              10.251.103.190.59794             ESTABLISHED 3
10.251.164.124. 445              10.254.0.220.58846
  • 当 CVO 中的某个节点发生故障转移时,浮动 IP 负责在故障节点与剩余正常运行节点之间迁移时保持数据连接。
  • 浮动 IP 不在 VPC 网络区域的 CIDR 范围内。
  • 在上面的示例中,如果任何客户端仍连接到问题节点上的本地数据 LIF ,而不是通过浮动 IP 连接,则会发生 CIFS 中断,直到故障节点重新启动并为本地 LIF 恢复连接为止。
