Package: grub-pc
Version: 1.96+20080724-16
Severity: normal
I have kvm configured to make disks available as virtio-blk devices,
and now I am trying to install grub2 onto them.
This works on plain VMs:
vera:~# ls -l /dev/vda
brw-rw---- 1 root disk 254, 0 May 2 11:01 /dev/vda
vera:~# grub-install /dev/vda
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.
(hd0) /dev/vda
However, trying to install to a system with RAID1 across two virtual
disks, I run into two errors, depending on which approach I take:
mdadm-test:/boot/grub# ls -l /dev/{md0,vd[ab]}
brw-rw---- 1 root disk 9, 0 May 2 10:07 /dev/md0
brw-rw---- 1 root disk 254, 0 May 2 10:07 /dev/vda
brw-rw---- 1 root disk 254, 16 May 2 10:07 /dev/vdb
mdadm-test:/boot/grub# cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 vda[0] vdb[1]
1572800 blocks [2/2] [UU]
unused devices: <none>
mdadm-test:/boot/grub# grub-install /dev/md0
grub-setup: error: Unknown device number: 254, 0
mdadm-test:/boot/grub# grub-install '(hd0)'
grub-setup: error: Core image is too big for embedding, but this is required
when
the root device is on a RAID array or LVM volume.
mdadm-test:/boot/grub# cat device.map
(hd0) /dev/vda
(hd1) /dev/vdb
(hd2) /dev/vdc
(hd3) /dev/vdd
(hd4) /dev/vde
(hd5) /dev/vdf
(hd6) /dev/vdg
It does not matter if I do it manually with grub-mkimage/grub-setup
or let grub-install do it, the result is the same. But since
grub-install does not offer verbose output, here's the manual
rundown with verbose output, in case it helps:

I get the same result with grub2 1.96+20090402-1 from sid.
