My experience is somewhat different. Getting to the grub shell was easy, since I chrooted to the new / partition before rebooting after the install. Then after installing mdadm and updating initramfs and grub, I rebooted.

The problem I’ve got is that mdadm isn’t starting, so that grub doesn’t see the partitions on /dev/md1. In the grub console all I need to do is mdadm –auto-detect then exit and the boot continues. However, I don’t want to do that every time.

I notice that your root is /dev/md1 while mine is /dev/md1p1. If you’re simply using RAID 1, then your /dev/md1 may be readable even without mdadm starting. However, with a partitioned RAID array, I definitely need mdadm to be running. However, I don’t know enough about grub 2 to make it start.

Any ideas?
