Subject: grub-pc: grub 1.99-21 fails to detect mdraid partitions

Date: Mon, 16 Apr 2012 00:17:59 +0800

Package: grub-pc
Version: 1.99-21
Severity: critical
Justification: breaks the whole system

Upgrading from 1.99-17 to 1.99-21 on wheezy today renders the system
unbootable.
Grub cannot detect any mdraid partition and is therefor unable to load
the kernel.
Downgrading to 1.99-17 solves the problem.

Does it emit any error messages that might be useful to help us track
this down?

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.

Cheers,

Hi,

I had the exact same problem as Arne,

I ran:

"dpkg-reconfigure grub-pc"

and followed Colin's advice  by installing grub on all disks.

This solved the problem perfectly ;).

Error message for each HD is "error: no such partition".
Since I have 4 HDs, the message appears 4 times.

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

You install grub to the disks, not the raid array.  dpkg-reconfigure grub-pc should have all of your disks checked, or at least the one your bios boots from.

I believe this can be closed as NOTABUG.

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.


Best regards,
Luís Picciochi

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

This looks clearly like a series of misconfigurations to me.

I just installed a wheezy system that boots on a MD partition, and grub
did work in a breeze.

Should we close, or at least downgrade, this?

Subject: re: grub-pc: grub 1.99-21 fails to detect mdraid partitions

Date: Sat, 2 Mar 2013 17:34:16 -0500

control: severity -1 important

Downgrading the severity since those facing this problem incorrectly
configured grub for their setup.

Best wishes,
Mike
