Bug#567637: grub-probe fails to detect ext3 on raid1 (software raid on md0)

[Torsten Landschoff]

Hi grub team.

After upgrading my system, configuration of grub failed. I noticed but thought that the old installation in /boot should still work fine.

That turned out to be wrong. When booting the system the next day, I ended up in grub rescue mode. My interaction went like this:

grub rescue> insmod linux
error: the symbol `grub_env_find´ not found.
grub rescue> linux
Unknown command `linux´

So my system was unbootable. I think on upgrade, the old grub installation should be still available if the new grub does not install. This is probably more of an upstream problem...

Anyway, it turned out that downgrading to 1.98~20100115-1 fixed the problem. The step that is failing is grub-probe trying to determine the filesystem on /dev/md0.

Greetings, Torsten
