rescuing my Lv2 Raid with Grub

correct

i did:
   grub rescue>set prefix=(hd0,msdos1)/boot/grub
   grub rescue>set root=(hd0,msdos1)
   grub rescue>insmod normal
   grub rescue>normal

He takes the "set" commands silently but does not understand
the "normal" command.

I just booted with the ubu CD and trying to mount the partition home
in order to make a backup. The mount command replies:
"mount: unknown filesystem type linux_raid_member"

How can i mount that?

thx a lot really ...
