Hi, yes I do. You need grub2 (aka. grub-pc), you need to fill in mdadm.conf and update initrd. My grub.cfg won't tell you much since I am using LUKS, root entries are of type /dev/mapper/* which isn't relevant for you. But if you are using grub2 I doubt this is the problem, you need to populate mdadm.conf, generate new grub.cfg and maybe reinstall grub on (both) the raid1 disks, make sure the initrd is updated so that it will start arrays early enough, and that's it. Chroot on the new raid system, do necessary changes, and try again. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
