But if two disks which are not from the same mirror go down, I would like to be able to boot up without any problems. And as someone else mentioned, what else am I going to do with those 200mb? I'd rather maintain symmetry and not have to worry which disks /boot is on, as I'll know that if the data drive survives, then I won't have any problems with the boot drive either. Russ
