It shouldn't be unless you plan on booting from the array. When I setup my array at home I did not modify anything in boot. My system at home is running Ubuntu 8.04 server and I just built it a week ago so this is all still fresh. > The question at this point, is where do I need to configure the "boot" > option; and what would it be. The technical details are below. > single disk is /dev/sda1 In the /etc/fstab I would use the UUID to define the / (root), this goes the same for /boot/grub/menu/lst (in other words, use the UUID instead of the device name). All boot options are likely in /boot/grub/menu.lst unless you specifically requested LILO or some other boot loader for some strange reason. > raid array 5 > /dev/sdb1 > /dev/sdc2 > /dev/sdd2 > the /etc/mdadm/mdadm.conf > DEVICE partitions > ARRAY /dev/md0 > level=raid5 > num-devices=3 > metadata=00.90 spares=0 > UUID=275d06f7:703df9fd:baf54294:a0156108 > MAILADDR root > I use this howto as a template: http://www.gagme.com/greg/linux/raid-lvm.php It is pretty straightforward and easy to follow.
