Guys, basing on your experience, can you tell us, how does Grub2 react
on degraded raid? Does it respect md's point of view which disk is bad
and which is not? Does it cooperate well with mdadm in general?
Grub legacy was way easy, just setup on disk & read that disk, no raid
knowledge, no problems. I guess grub2 can be configured in that manner
too, but as it has raid/lvm/whatever support, may be give it a try...
I've got Debian Squeeze servers with grub2, without any mirroing, so
converting them into RAID1 system, wanna make it right.
