Details:
I use GRUB 1.99~rc1-13 (tested in Debian Testing and Fedora 14).
Currently, if I create a mdadm array with 0.90 metadata containing the /boot:
mdadm --create /dev/md0 --level=raid10 --raid-devices=2 --metadata=0.90
/dev/sda1 /dev/sdb1
mkfs.ext4 /dev/md0
and load raid and mdraid modules in GRUB, it works without problem.
In GRUB command line, "ls" command shows me (md0).
But, if I create my array with 1.2 metadata:
mdadm --create /dev/md0 --level=raid10 --raid-devices=2 --metadata=1.2
/dev/sda1 /dev/sdb1
In that case, grub "ls" command doesn't show the (md0).
It looks that GRUB doesn't support mdadm 1.2 metadata.
