Hi, This error come from lvm, perhaps you can try raid10 first. > > AFAIK both LVM and RAID10 are supported and it's possible to boot grub from > LVM volume, am I wrong ? > Or perhaps I'm missing something ? > Is there any example of LVM/RAID config files ? > What happens if array (RAID 5, 6, 10) is incomplete (disk failure/missing) - > maybe that's the problem ?

If you're using raid5/raid6 and one/two of the disk is missing or corrupted, you need to add module raid5rec/raid6rec using the --module option in grub-install. -- Bean _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
