NFS问题搞好久,请高手帮帮忙
我的环境是RH9+skyeye0.9.8+uclinux-20030522在uclinux下输入:
mount -t nfs 10.0.0.1:/opt/target /tmp
出现列下错误:
RPC:sendmsg returned error 101
portmap:RPC call returned error 101
RPC: sendmsg returned error 101
postmap:RPC call returned error 101
lockd_up:makesock failed, error=-101
PRC: sendmsg returned error 101
portmap:RPC call returned error 101
mount: /etc/mtab:Read-only file system
以上是出错的信息
nfs,portmap,network服务都启动了,并且防火墙也关了. 加一个 -o nolock就没RPC的错误了! 谢谢 hcllh 没有RPC错误了.
但是
mount -t nfs -o nolock 10.0.0.1:/opt/target /tmp
还有一个错误:
mount: /etc/mtab:Read-only file system :-(
大家没有遇到这样的问题吗? 这个问题解决不了就不能向下面走了.
帮帮忙! 顶一下! 有没有可能是skyeye.conf的配置问题 你的根文件系统是只读的，运行一下mount 命令，重新把根文件系统挂载成可读写的就可以了 你的根文件系统是只读的，运行一下mount 命令，重新把根文件系统挂载成可读写的就可以了谢谢版主回帖
我没有搞明白:你是指主机上的(/)根目录下是只读还是指uclinux上的/根目录只读
然后怎样运行mount 加什么参数??
请版主帮我看回一下. 主要的问题是你的NFS能否使用？我用skyeye NFS的时候，也有这些告警，但是NFS 使用是正常的。如果有时间，你可以参考我以前用NFS boot 根文件的帖子。 你的根文件系统是只读的，运行一下mount 命令，重新把根文件系统挂载成可读写的就可以了谢谢版主回帖

请版主帮我看回一下.
KSH版主能详细解答一下吗？我也遇到这样的问题。 可以尝试着运行:
mount -n -o remount,rw / 我试过了,还是不行呢.
我的配置:redhat9.0 skyeye0.9.8 uclinux20030305
在uclinux配置的时候选上了 nfs nfsv3 busybox 里也选上了mount的命令
主机的nfs测试过可以用的.
skyeye.conf如下

怎么让uclinux启动时的文件系统就是可读写的呢?是在skyeye可以配置的还是要在uclinux里面配置的呢?
是不是一定要用nfs做跟文件系统skyeye才能mount呢?
