Since you're new to this list, and this topic, I'm going to spare you the
headache. Don't use RAID5 Even with a hot-spare, if you use large drives
chances are you'll loose everything if one of the drive fail and you need
to rebuild the whole set.
Rather use RAID 10. The newer CentOS installation disks has an option to
setup RAID10, alternatively.
There are numerous tutorials out there on how todo it, but this one seems
quite easy to follow:
