Dave, I've been using software raid with every type of RedHat distro RH/CentOS/Fedora for over 10 years without any serious difficulties. I don't quite understand the logic in all these negative statements about software raid on that wiki page. The worst I get into is I have to boot from a bootdisk if the MBR gets corrupted for any reason. No big deal. Just rerun grub.

have you been putting /boot on a mdraid? that's what the article is recommending against.

I've always put a static boot on each drive, then made the REST of the drive a mdraid mirror and put a LVM in it. all that needs to be done is to rsync the primary /boot with the backup following any kernel updates.
