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 have fc10 2.6.27 with two USB 1.5Tb external drives on FAT32. They are mounted as /mnt/v1 and /mnt/v2 using the LABEL= to make sure they mount up correctly each boot (random device names depending on the order i switched them on). I have exported /mnt/v1 and /mnt/v2 over NFS.
When I mount these from another machine I get the first of the two mount points (as appears in /etc/exportfs) duplicated on both mounts. eg mount lister64:/mnt/v1 /data/v1 && mount lister64:/mnt/v2 /data/v2 gives the contents of /mnt/v1 in both /data/v1 and /data/v2.
I assumed that this is because the fsid is the same (0??) for both mount points - is that assumption correct? If so - I went onto adding the option fsid=1 and fsid=2 into the /etc/exportfs file and re-exporting.
With fsid set to anything other then 0 I am unable to mount at all - and syslogs shows mountd[xxxx]: refused mount request from xx.xx.xx.xx for /mnt/v1 (/): not exported.
What am I doing wrong?? I have spent days on this - I hope it's me being dumb!. Any hints appreciated!
Can anyone confirm that the reason that when i mount either /mnt/v1 or /mnt/v2 and get the same filesystem is because of fsid's being the same? (the UUID of both drives is 0000:0000 or something like this!)
