I have been trying to install CentOS 4.1 on a new server today. The installation went fine but the system doesn't boot. It doesn't even get to the Grub screen. The system has a 3ware 9500 series controller and 12 250GB SATA disks which are configured for RAID5 with one hot spare. I searched on the web and noticed that this is a Grub (and Lilo) limitation. Is there any way around it other than setting up a smaller RAID device? -akop

The only reasonable ways to get around that is to split your array into <2TB pieces or to get another disk for booting... Lilo has the same issue - so you're not gonna be very happy. Peter.

The root filesystem can be on the larger partition without any problems as long as /boot is in a <2TB partition it will be happy.
