Bug#668920: grub-pc: grub 1.99-21 fails to detect mdraid partitions
Package: grub-pc
Version: 1.99-22.1
Followup-For: Bug #668920
Transitioned to grub2 from LILO and saw this problem as well. After booting
rescue mode, fixing up prefix and root, and loading the raid modules, grub
still doesn't see my md device at all. I tried using grub-install to include
the RAID modules early, but that did not seem to help either. Going back to
LILO for now.
Thanks,
Adam

Bug#668920: grub-pc: grub 1.99-21 fails to detect mdraid partitions
Hi, My setup is somewhat similar as my root partition is also on a RAID1 array with two disks. GRUB is installed on both of them. This is just to note that I did not reproduce the reported problem when I recently upgraded from 1.99-17 to 1.99-21. The upgrade went on swiftly as always.

Does it emit any error messages that might be useful to help us

Error message for each HD is error: no such partition.
Since I have 4 HDs, the message appears 4 times.
Downgrading to 1.99-17 solves the problem.

* grub-pc/install_devices: /dev/sdc
This jumped out at me. Are you quite sure that your BIOS is
actually booting from /dev/sdc? It's possible that it's attempting
to boot from an old copy of the GRUB core image installed to a
different disk, which then gets confused by the newer modules in
/boot/grub/. In this theory, downgrading to 1.99-17 would help
because perhaps that core image is ABI-compatible with those
modules; the support for non-512-byte sectors in 1.99-19 was
probably a core/modules ABI break so this is plausible enough.
My standard advice is to install GRUB to all fixed disks
('dpkg-reconfigure grub-pc') unless you have a good reason not to.
I remember I installed grub on all disks when I set up the machine.
However, 'dpkg-reconfigure grub-pc' doesn't give me any option to
configure that any more. I tried a manual 'grub-setup /dev/md127 ;
grub-setup /dev/md1' after installing the new version, but it didn't
help. grub-setup doesn't let me install on /dev/sd*, since the disks
are grouped into raid arrays now.
The boot device is /dev/md127 and the root partition /dev/md127p1.
(Itʼs named md127, because when I installed squeeze on the machine, I
chose the name md0 for the first raid array, not knowing that it would
secretly rename it to md127, since it somehow doesn't like the
numbering start from 0.)
Attached is my grub.cfg
HTH
Cheers
Arne
