Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I'm running a CentOS 4 server with a reiserFS partition mounted as /home/public (I've recompiled the kernel to include RFS support and can read/write as normal to that device).
My /etc/exports shows my client computer's subnet (192.168.1.0/255.255.255.0) and the fact that it should be exported '(rw)'. There is nothing in /etc/hosts.deny, and in /etc/hosts.allow portmap is set to accept from the same subnet. I have restarted the nfs and portmap daemons after adjusting all config files. I have included an iptables rule to accept anything coming from the server (based on source IP).
From the client, if I mount the device (192.168.1.103:/home/public), I get a 'cannot read superblock' error after some minutes. If I include the "-o nolock" option, it mounts up just fine. However, the device is mounted as read-only; definitely not the behavior I want nor expect.
Is there some fundamental aspect of NFS I'm missing? I've had wonderful success with these same settings on Slackware in the past, but for some reason I'm hitting a wall I can't see over.
I'm using Slackware 11 for the client computer -- I'm sure the UIDs don't match but the directory I was attempting to write to as a test has 1777 permission. I was just trying to create a 'Transfer' directory in which to put things to be sorted once I had more time.
