If you used LVM partitions, you only need to add another partition to 
that partition.  Then grow the file system.

If you have not used LVM, then look at splitting your partitions around 
and going from there.  How much space and what partitions do you have.

I normally put my home on a separate drive and then put the OS on it's 
own drive.

Can you supply a df -h of your system?
