Hi there: My raid1 is running fine on /dev/hda(boot disk) and /dev/hdc. ;;Modified /etc/lilo.conf(Add one section for initrd.raid.img) Two cmds issued: mkinitrd /boot/initrd.raid1.img --with raid1 2.2.12-20 lilo -v ;;No warning. Then, power down, remove /dev/hdc, power up. /dev/hda is able to boot up. /proc/mdstat indicates it's running on partitions from /dev/hda only. Everything works as expected. (Partitions on /dev/hda and /dev/hdc are symmetrical) But if raid1 is running and /dev/hdc is boot disk, with same steps repeated I can't boot up. I see "01 01 01 ..." continuously running on screen. Same steps means the following: Modified /etc/lilo.conf from previous operation(from /boot/lilo.conf in /dev/hda, except "hda" was replaced by "hdc".) Two cmds issued: mkinitrd /boot/initrd.raid1.img --with raid1 2.2.12-20 lilo -v ;; get warning saying /dev/hdc is not the first disk. Then, power down, remove /dev/hda, power up. Can't boot up!! What am I missing here? Is "lilo -v" the problelm? Any help is appreciated.
