Grub does not understand raid boot. However, if you are just using raid 0, you can setup grub on both (all) disks. Also, I've heard that you can tweak grub so that if the primary MBR isn't working it will use the secondary one and similarly for primary/secondary grub.conf/menu.lst Now if for some far and away reasom you are using other raids (for boot), you can't use grub. It's early stages simply don't understand the raid, so it won't be able to find grub.conf on the /boot filesystem. > I am planning to raid1 my server and was going to follow the gentoo > howto for raid which suggests grub and doesn't mention lilo. Since raid1 is performance-enhancing, I would simply not raid1 boot (I don't even mount boot most of the time). Instead you can raid0 boot, or simply use the space that would be boot on the second drive as supplemental swap. (It won't be as fast as raid1 swap, though.) If you are comfortable with lilo, you could just go that way, but I'm not very experience with lilo. -- Boyd Stephen Smith Jr. [EMAIL PROTECTED] ICQ: 514984 YM/AIM: DaTwinkDaddy -- [email protected] mailing list
