换了网线异常了，CRS无法正常启动，clssnmSendingThread: sending status msg to all nodes[通俗易懂]

换了网线异常了，CRS无法正常启动，clssnmSendingThread: sending status msg to all nodes
同事换网线前我将节点2正常关闭了，换完网线告诉我，发现节点2死活起不来了，看上面的日志和一些帖子最后也没解决，尝试过重启、网线拔掉重新插上、查看过存储是否正常和存储重新挂载。。。。看过一个帖子说可能是OCR信息发生了改变，不过之前没备份，也没忘这方面深入考虑。
最后还是没搞定，主要是技术有限，没准确的定位出具体问题也不敢轻易乱动。。。

根据日志能判断出bond信息变了吗？我当时没发现也没分析出来，最后同事说改了bond！当时不是说只换根网线重新排下线吗？我说改回去试试，果然如此，重启一切正常了

胡乱重启了下，没起来。。。

抛开技术行不行先不说，单这件事来说，同事之间的合作有时候更重要。一不小心你就会给别人挖个坑或掉到别人给你挖的坑
