software-raid

I have CentOS 5.8 on my computer, with 5x 1TB hard drives.

I used software RAID. (RAID 1 as a boot partition md0, RAID 0 as a root partition md1 and RAID 5 as /home partition md3).

Unfortunately one of these hard drives failed lately and I want to replace it with a new one.

I want to know that is it possible to change this hard drive without data loss?

The important partition is RAID 5 so in theory if one of hard drives failed I should be able to recover its data without any problem. But in practice how can I do that?
