Root-NFS：安裝rootfs時返回錯誤-5

我嘗試在我的設備上加載嵌入式Linux。Root-NFS：安裝rootfs時返回錯誤-5

內核命令行：

setenv bootcmd 'nfs 10.0.0.1:/home/master/rootfs3/boot/uImage;bootm;' 
setenv bootargs console=ttyTX0,57600n8 root=/dev/nfs rw nfsroot=10.0.0.1:/home/master/rootfs3 ip=dhcp init=/sbin/init

系統加載失敗：

Server returned error -5 - 這是什麼意思，我從哪裏可以知道這個錯誤？

好的，我發現'error-5'的意思是'NFSERR_IO'（看'include/linux/nfs.h'）。這也可能是一個磁盤錯誤（請看http://www.ietf.org/rfc/rfc1094.txt）。但是我怎樣才能解決這個錯誤？ – ymn

1.停用防火牆在我的Fedora 18 systemctl停止firewalld systemctl禁用firewalld

2.停用SELinux的 VI的/ etc/SELinux的/配置

- 評SELINUX =執行 - - 添加＃SELINUX =禁用

重新啓動您的linux。
