I am trying to install squeeze (from live DVD[1]) with a RAID1 root
filesystem (/dev/md0).

There is an error when running grub-install:
Jun 5 18:38:18 grub-installer: error: Running 'grub-install --no-floppy --force "/dev/sda"' failed.

I tried to run it manually:
chroot /target grub-install --no-floppy --force /dev/sda
/usr/sbin/grub-probe: error: no such disk.
Auto-detection of a filesystem of /dev/md0 failed.
Please report this together with the output of "/usr/sbin/grub-probe --device-map=/boot/grub/device.map --target=fs -v /boot/grub" to <bug-grub@xxxxxxx>

Does "/target/etc/mtab" exist and is it correct?

Seems like it's correct:
----------------------
/dev/md0 / ext3 rw,relatime,errors=remount-ro,data=ordered 0 0
tmpfs /dev tmpfs rw,relatime,mode=755 0 0
none /proc proc rw,relatime 0 0
----------------------


chroot /target /usr/sbin/grub-probe --device-map=/boot/grub/device.map --target=fs -v /boot/grub
/usr/sbin/grub-probe: info: the size of hd0 is 488397168.
/usr/sbin/grub-probe: info: the size of hd1 is 488397168.
/usr/sbin/grub-probe: info: changing current directory to /dev.
/usr/sbin/grub-probe: info: changing current directory to mapper.
/usr/sbin/grub-probe: info: opening md0.
/usr/sbin/grub-probe: error: no such disk.

On both Debian and Ubuntu, I used to be able to run "dpkg-reconfigure
grub-pc", choose md0, sda, and sdb, and grub would be installed on all

This results in the same error.

three. For a while now (I can't remember for how long), installing to
md0's failed.

Is this a known bug or unsupported?


When trying to install lilo (with the debian-installler), I get
"inconsistent raid information" (but the RAID1 (2x 208G) was created
with debian-installer):

Jun 5 19:22:00 in-target: Running lilo...
Jun 5 19:22:01 in-target: Fatal:
Jun 5 19:22:01 in-target: Inconsistent Raid version information on /dev/md0 (RV=0.90 GAI=1.2)

What do RV and GAI mean? I've googled both and not foudn anything to
help. "0.90" and "1.2" are mdraid metadata versions. Were these disks
previously in another array and do you now have two types of metada on
them?

No, I did not change any hardware config before reinstalling with
squeeze. I also had a RAID1 root fs with those two disks before.

I think it is justified to file a bug against debian-installer.

Thanks,
