rescuing my Lv2 Raid with Grub

Hi all,

this morning my desktop booted with errors. I repeatedly ran fsck
and rebooted. It finally booted directly into grub. Look:

grub rescue> ls
(md/1) (md/2) (md/0) (hd0) (hd0/msdos3) (hd/msdos2) (hd0/msdos1) (hd1)
(hd1,msdos3) (hd1,msdos2) (hd1,msdos1)

grub rescue> ls (md0,1)
error: unknown filesystem

Trying "ls" on them all gives "error: unknown filesystem" except for
some windows FS. The problem is, the only windows i have there is
running inside a virtualbox. I cannot boot it from grub.

I dont know how to go further ... any help?

It is a raid level 2 (see on the md points) under ubu 12.04.

thx a lot for any help ...
