Re: RAID 1 cannot boot (using grub)

[Steven Dake <sdake@mvista.com>]

Derek,

Lilo supports booting to RAID 1 volumes, and I know it has worked since 
I've tested it.

As for GRUB, I've never managed to get it to work, but I have not tried 
with a new grub for 9 months atlesat.

So the recomendation is to try lilo.

Good luck
