Bug#685530: grub-common: btrfs raid1 root

[Marc Glisse]

Package: grub-common
Version: 1.99-22.1
Severity: normal

Hello,

I just installed debian testing on a computer with 2 hard drives. I
installed in a btrfs partition on one drive, then added a partition from
the second drive to make it a raid1. I additionally marked that extra
partition as "boot" and used dpkg-reconfigure to ask grub to install on
both drives. Now if I remove the first drive (after all, the point of
raid1 is that this drive may die), the computer won't boot (some message
about an invalid filesystem). I think there is some magic in place so
grub does the right thing with md arrays (lets each partition believe it
is the first one), could it be that it needs extending to the btrfs
case?
