I think you need to tweak your kernel lines in /boot/grub/menu.lst to include the following clause: md=1,/dev/sda2,/dev/sdc2 ...assuming I didn't misinterpret your configuration information. :-) You should be able to append this right onto the end of the existing options. This tells the RAID module explicitly to assemble device /dev/md1 from the listed physical devices. This works fine for me on an x86 system at home and an alpha system at work. :-) Cheers, Scott - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
