Hi, I have setup raid on a new server and have found that if I remove one drive it will boot but if I remove the other it says missing OS. I am using two 18.2Gig SCSI drives, using software raid 1. I have it setup with the following drives in this order. /boot swap / all are mirrored between the two drives. I remember a while back that their was a problem with grub would that be the problem here? Why does it work on one drive and not the other? Thanks Mace

Dig through the list archives for instructions on fixing it. -- Bowie
