Once you have included /dev/hdc1 in an array, don't touch it again - just access the array (/dev/md0). > cp -ax / /mnt, tweak /etc/fstab ... /dev/md0 mounts fine, tweak lilo > conf to boot from /dev/md0, reboot -- fine, finally come to add > /dev/hdb1 into the array after resetting the partition type to > autodetect RAID ... You missed a step (step 9). You have to reboot so that /dev/md0 is your root device. Once you have done that and are happy with it, you add in /dev/hdb1 and let it resync.
