Bug Description
Binary package hint: grub
Running on jaunty RC with a system installed on a RAID1 array. Starting the system with only the second drive plugged in gives a grub error 21. Moving the second disk to be the primary drive will make the system boot correctly from the degraded array.

I have performed a new installation into a kvm of today's Jaunty amd64 server.
2 disks, 2 GB apiece, qcow2.
Both are partitioned into a single raid partition, raid1 together,
serving / on ext3. No separate /boot, or swap partition. Note that I
needed 256MB of memory for this to work.
I was then able to boot degraded in each of the following four cases:
kvm -hda server1.img
kvm -hdb server1.img
kvm -hda server2.img
kvm -hdb server2.img
That's using each of my disks, in each of the first and second disk position.
In all 4 cases, grub found a bootloader, started the kernel and
initramfs noticed that a disk was missing.
I have not yet been able to reproduce the problem, Mathias. There
must be something with the way in which libvirt calls kvm that's
introducing this problem...
