问题描述

多个存储节点 在事件日志中显示以下消息、并且未报告处于未解决状态的错误。
Errors observed on interface ethx
 
如果报告的节点在指定的ethx接口上收到如下所示的RX错误

可以尝试以下故障排除步骤
  • 记下连接到同一网络的节点总数。
  • 确定哪些节点正在运行问题描述、哪些节点未运行。通过Active IQ事件消息对此进行验证。
  • 所有存储节点(eth0和eth1接口)均连接到两个交换机:所有eth0接口均连接到交换机A、所有eth1接口均连接到交换机B
  • 对于未显示"Errors observed on interface ethx"(节点日志中的RX错误)的所有存储节点、请检查其连接到的交换机端口。查看交换机日志、了解连接到未报告问题描述的存储节点的交换机接口上的任何CRC/TX/RX错误。
  • 如果您在交换机日志中看到同一接口的CRC/TX/RX错误、请将eth0接口缆线与同一存储节点上的eth1交换。检查交换机日志是否显示同一交换机或不同交换机上的错误、以隔离故障硬件(可能是故障SFP或缆线)。
