nfs:server is not responding,still trying的解决方法(转)

方法1 : 我在arm上通过NFS共享文件时出现下面的错误提示 nfs:server is not responding,still trying
原因分析:NFS 的默认传输协议是 UDP,而PC机与系统通过UPD交互时就会出现严重的网卡丢包现象。
解决方法:在客户端改用TCP协议,使用下面的命令, #mount -o tcp 10.10.19.25:/home/export /mnt/local
方法2: 在目标板上通过NFS复制PC机上较大文件到目标板上的时候遇到的问题: nfs: *** not responding, still trying
修改方法: nfs mount时候出现的NFS崩溃,按照以下的方式mount mount -t nfs -o intr,nolock,rsize=1024,wsize=1024 192.168.1.3/root/somedir /client

附 问题四:在测试时,“./progressbar -qws”后出现如Q3一样的提示 ,按Q3来处理。 以上参考了一些 “快乐的天空”的经验,他的网页是: http://blog.chinaunix.net/u2/67519/showart_677885.html 他的 mount -t nfs -o intr,nolock,rsize=1024,wsize=1024 192.168.1.3/root/somedir /host 应该改成 mount -t nfs -o intr,nolock,rsize=1024,wsize=1024 192.168.1.3/root/somedir /client |
