FC2: Grub & 4 x SATA w/ Linux SW Raid on a P4P800

[Mike Fedyk]

Hi guys,

I'm trying to setup SW raid on this system, and luckily didn't hit the 
"kernel won't boot" bug reported for this MB.

There are two sata (1 Promise 20378 & 1 Intel ICH5), and one ICH5 PATA 
controllers on this motherboard.

The issue seems to be that the fedora installer starts the ata_promise 
(promise sata driver) before ata_piix (intel sata driver), but the bios 
(and grub after the reboot) sees the disk ordering with the Intel 
controller first.

I did a test install with / on SW RAID1, and was able to run "find 
/boot/grub/stage1" in the grub command line and run the appropriate 
"root (hdX,Y)" and "setup (hdX)" (where X and Y means drive number and 
partition number respectively).

The problem is that "find /boot/grub/stage1" hangs from the grub floppy 
I created (as specified in the grub info pages with the "dd" command) 
with the extra partitions I've setup (what I want for my production 
setup) with /boot in raid1, and / on raid5 and three other raid5 
partitions as mentioned below.

I have attached a file with /proc/partitions output, and "fdisk -l" 
output for each of my four SATA drives.

md0 is /boot as RAID1 on sd[ab]1 (100MB each partition)
md1 is /  as RAID5 on sd[ab]2 and sd[cd]1 (10GB each partition).
The rest of the partitions are /web /ftp and /mail, for the planned 
services to be run on this server (but I don't know the default 
locations for those in RH/Fedora, so these are temporary names).

Any ideas on how to get this working?

Thanks,

Mike
