A year ago I posted about getting nfs set up for a local network as part of a longer post -- here it is reposted, with minimal changes to make up for the substitution of portmap for rpcbind in debian. Hopefully it'll be clearer. Also, nfs is such a universally useful thing that it should be promoted among a wider audience.
I followed this post to get up and running (scroll down) with nfs. Here's my take on it:
UPDATE: with the first comment below in mind, I changed this post a little bit. The folder /shared on the master node is shared with the client, which mounts it under /home/me/shared, instead of sharing the folder /home/me/shared on the host and mounting it as /home/me/shared on the client. I basically want to drive home the message that you're mounting an NFS share in the same way as any other disk resource -- you can mount it in whatever location you want, regardless of where the folder is found on the host.
Server
On the master node (here: 192.168.1.1 - beryllium) which hosts the shared folder on its harddrive:
sudo apt-get install nfs-kernel-server nfs-common rpcbind
Let's share /shared
Create it
sudo mkdir /shared
Set permissions for 'all' to be read, write and execute
sudo chmod a+wrx /shared
Edit /etc/exports by adding a line to the end of the file
/shared *(rw,sync)
[Note that this (the *) is inherently insecure. You should restrict access to the NFS mounts via your firewall (e.g. using iptables with -A INPUT -s 192.168.1.0/24 -p udp -m udp --dport 2049 -j ACCEPT; -A INPUT -s 192.168.1.0/24 -p udp -m udp --dport 111 -j ACCEPT for a local subnet 192.168.1.1-255). You can also use
/shared 192.168.1.0/24(rw,sync)
to restrict it similarly directly via /etc/exports. There are more things that can be done, see e.g. here and here. If you are running a cluster with a separate subnet, this is not a great worry. If you are in a situation where security is important, consider using sshfs instead.]
Make stuff happen:
sudo /etc/init.d/nfs-kernel-server restart
sudo exportfs -a
Client
On each client node:
sudo apt-get install rpcbind nfs-common
mkdir ~/shared
Add the following line to the end of /etc/fstab
beryllium:/shared /home/me/shared nfs rw 0 0
You can mount in a different location if needed -- server:serverfolder localfolder nfs rw 0 0
To get it up and running immediately instead of waiting for reboot:
sudo mount ~/shared
That's it!

This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
