Hard drive partitioning of a cluster's headnode

Hi!

I built a HP cluster, but I'm still very ignorant about Linux. However, the headnode has a small partition for Windows XP, and a large Linux partition. Someone advised me to put the users' files on a separate partition, because when we start with serious computations, the output files are really big and it will clutter up everything else.

I have a GParted CD and I used it a while ago when I shrunk the XP partition.
Now, I guess I first have to shrink the existing Linux partition, and then create another partition, and then somehow copy the /home tree onto that. Am I right? How should I go about doing it?

Code:

[compchem@gnlserv01 /home]$ df -a
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                     421277880  17382932 382150104   5% /
proc                         0         0         0   -  /proc

devpts                       0         0         0   -  /dev/pts
/dev/sda2               194449     12734    171675   7% /boot
tmpfs                  4095892        12   4095880   1% /dev/shm
none                         0         0         0   -  /proc/sys/fs/binfmt_misc
sunrpc                       0         0         0   -  /var/lib/nfs/rpc_pipefs
nfsd                         0         0         0   -  /proc/fs/nfsd

I have 8GB RAM on the headnode, but only 2GB for the swap partition. Is it necessary to enlarge the swap space, and how do I do it?

Thanks!
