金庸群侠传笑傲江湖:nfs:server is not responding,still trying 原因与解决方案

来源：百度文库 编辑：九乡新闻网 时间：2024/04/28 03:23:29
今天，用开发板通过nfs挂载主机，想从主机上面拷贝一些资料，可是竟然出现：nfs:server is not responding,still trying ， 我用的是友善之臂的mini2440，操作系统使用的是Ubuntu8.04。
    本来还以为是nfs出了故障，但是google了一下发现原来不是nfs的原因，而是由于传送的数据太大，出现数据包丢失现象。
   NFS 的默认传输协议是 UDP，而PC机与嵌入式系统通过UPD交互时就会出现严重的网卡丢包现象。可用的解决方案是：在客户端改用TCP协议，使用下面的命令，


mount -t nfs -o intr,nolock,rsize=1024,wsize=1024 192.168.0.121:/主机nfs目录 /挂载路径
   注意：中间使用的是逗号，而非英文中的句号。
