I'm trying to copy an existing system on a new md array. But I can't get the system to boot off the new disks. Ubuntu Natty. I have Kubuntu CD, I boot off that, reinstall mdadm, then:
sudo -i mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 mdadm --assemble /dev/md1 /dev/sda5 /dev/sdb5 mdadm --assemble /dev/md2 /dev/sda6 /dev/sdb6 mdadm --assemble /dev/md3 /dev/sda7 /dev/sdb7 mkdir /md0 mount /dev/md0 /md0 mount /dev/md1 /md0/var mount /dev/md3 /md0/home mount -o bind /dev /md0/dev mount -t proc none /md0/proc mount -t sysfs none /md0/sys chroot /md0
Then try to reinstall grub #aptitude reinstall grub-pc :

I've been trying to get the new system to boot for ages, but keep failing to do that, and I don't know where to go from here. Can someone assist?
