However, Centos4 won't boot at all with a similar install attempt and running grub-install in rescue mode gives an error about not being able to find the bios drives. Is there a howto somewhere to work around this problem?
This is an infamous grub-on-sw-raid problem. I run this script after installing the OS on the new system (and after grub upgrades ...
Thanks - this is just the first time I'd seen where it didn't at least install on the first drive automatically. I had to run grub by hand from a rescue cd boot to fix it. Also, most of the instructions I found about installing on the 2nd drive were for IDE controllers and a bit different. Your approach gets it right for SCSI where a failure on the 1st drive makes the device names shift up. At least it works in a simulated failure where the 1st drive is removed. Does anyone know if there is a common failure mode where the 1st SCSI drive is still detected at boot as /dev/sda but doesn't work?
