Make a 500M partition on each of the 4 drives as the first thing you do. Put /boot on /dev/sda and leave the others blank/unused. Make the rest of your partitions into your RAID 5 and your set. After everything is installed and working, (as root) mkdir /boot2 mount /dev/sdb1 /boot rsync -rvup /boot/* /boot2 umount /boot2 mount /dev/sdc1 /boot rsync -rvup /boot/* /boot2 umount /boot2 mount /dev/sdd1 /boot rsync -rvup /boot/* /boot2 umount /boot2 This way, if /dev/sda takes a dump, you'll have to boot a rescue disk, chroot to /mnt/sysimage and 'grub-install /dev/sda' (because when you remove /dev/sda, another will take it's place). But that's not very difficult. Suggest that you do RAID 0 + 1 or RAID 6 (if that's possible in Anaconda). Big hard drives are cheap these days, RAID 0 + 1 gives you speed and reliability. If speed and reliability are not your thing, then RAID 6 is a much better choice than RAID 5.
