Increase Disk Space in a Raid 5 Live System – Red Hat 7.1

I am currently running RedHat 7.1 on my Machine, which have two disks that are raided. I have used up all the space and would like to increase disk space by adding two new hard disk. I am a new Linux user, can anyone help me in increasing disk space (still raided) without causing any problem to my current system.

Thanks in advance.

2 disk can only be in RAID 0 or 1, not 5

Have a look at http://unthought.net/raidreconf. Remeber though that manipulating disks without prior tests and experience is always dangerous (no matter what OS and tools you use)
