As Les mentioned, what part of NFS failed?  I use NFS, and I couldn't
get along with out it (4.1/FC2).   Check and make sure the FIREWALL on
your first server is not blocking NFS mount requests (you can
temporarily disable it using "service iptables stop").  Next, have you
configured the file /etc/exports ??  That is where the NFS "mounts" are

Basically, you should have (anyone disagree w/ sync?) in /etc/exports
(unless, you aren't mounting /home, but another directory).
/home        server.ltsp.two(rw,no_root_squash,sync)
You need to make sure the NFS server is reloaded (as well as
reloading... otherwise it does not see changes to the config file....
that works for most server services... although some are smarter and
check for updates).

run "service nfs reload"... if it gives you failed, you aren't running
the NFS server.  To quickly turn in on, run "service nfs start".

Make sure you have "server.ltsp.two" defined in /etc/hosts... otherwise
your system won't know what IP address belongs to server.ltsp.two.

Now on your 2nd server, you can run "mount server.ltsp.one:/home /home"
which mounts the /home directory on server.ltsp.one on the local
directory "/home".  Make sure again, you have the IP address of
server.ltsp.one defined in /etc/hosts....

NFS should work.  I've got 2 servers and my workstation all mounting
directories off each other (/home from main LTSP server, /home1 from my
system, /universal from my Linux Fileserver).

What are the specs on the 1st server (hardrive in particular)?

Keep us posted.
