Fedora Core 2 Test 3 - NFS server: server is down

在NFS Server切换到一个新机器后，发现部分机器无法mount。
Server系统FC2
F7可以正常mount，FC6提示错误，FC1提示服务关闭。

Google了一下，下面是结果：

I installed FC2T3 on one of my machines and could not mount any NFS-Dir from my Server (SuSE 8.2). With FC1 on my other machines I have no problem at all mounting any NFS-Dirs from the server.

[root@flaneur root]# mount 192.168.1.2:/home
mount to NFS server '192.168.1.2' failed: server is down.

SELinux and the firewall are already disabled...

Has anyone any suggestions?

I got a solution for this problem - thanks to Ron McKown and the fedora-test-list:

You should mount your nfs-dir with the "nfsvers"-option like this:

mount -o nfsvers=2 192.168.1.2:/home

好久没有搞NFS了，都忘记的差不多了
