An interesting NFS mounting problem

[Zhou, Jingchen]

I am having a problem to mount a NFS volume /home (exported by a RHEL4 server nfs0) on a NFS client which is also RHEL4.

The server (nfs0) is configured as such
$ cat /etc/exports
/home nfsclient1(rw)

and the client (nfsclient1) as such:
#cat /etc/fstab
nfs0:/home            /home           nfs     defaults        0 0 

When the client boots up, I get the following error message:

"Mounting NFS filesystems: mount: mount to NFS server 'nfs0' failed: System Error: No route to host."

However, I have no problem to ping the server (nfs0) from nfsclient1 and I also can mount /home manually via e.g. "mount /home" from command line.

Am I missing any?

Thanks,
JC
