I have a feeling > though that /boot might not be able to be part of the raid setup? you cannot boot from raid5, but you can boot from raid1. if you want to boot from raid1, to be able to boot from the second disk if the first fails, you will need to manually install a bootloader on the second disk; SuSE's installer will not do this for you. one thing i'll point out is that if you decide to go non-redundant for your /boot filesystem, i would put it on a degraded raid1 array so that if you ever change your mind and want to add another disk to make it redundant, you can just plop it into the pre-existing degraded raid1. (but the SuSE installer won't create degraded arrays, so you'll have to go to the command line and do it manually.) > So ... anyone out there been through this before and have some > suggestions for me?
