hi ya rudy
your setup looks good ...
what is your partition type from "fdisk /dev/sda"
- it should be raid ( linux raid type )
lilo.conf looks correct for boot= and root=
( "correct" == the way i do it and works for me )
- nothing wrong with lilo.conf
- other last issue is that is just a dumb lilo problem
and nothing to do with raid
( a few painful experiments )
- try using "linear" instead of lba32
- you can also try removing "install="
- you should remove "raid-extra-boot"
( i haven't seen it before )
- it's a good test you're doing to disconnect sda
to see if its boots .. also repeat with a disconnected sdb
- and verify that written data to one disks
is sync'd to the other disk when its "reconnected"
watch it syncing with "cat /proc/mdstat"
- last option is to use syslinux or grub instead of lilo
