Depends if your using RAID or not.  I can't answer you of you are as I 
am still learning this myself however of you aren't and your using a 
later build of the CentOS/BQ CD then you should be using LVM.  You can 
read the HOW-TOS at http://tldp.org/HOWTO/LVM-HOWTO/

For example, if your just adding space to a non-system partition you can 
simply do this...

     * lvextend -L400G /dev/VolGroup00/LogVol06
     * umount /backup
     * e2fsck -f /dev/mapper/VolGroup00-LogVol06
     * resize2fs -p /dev/mapper/VolGroup00-LogVol06
     * mount /backup
