Thanks for the reply. i am indeed using software RAID, not any RAID included with the motherboard. Your configuration is much more complicated than mine, and your RAID 5 is much larger than mine, so no reason mine shouldn't work. I will double check settings in my BIOS to make sure it isn't causing problems. I don't think I will put swap and boot on RAID, just /. looking at your setup, I couldn't see anything I did wrong.

Mike, I think in that case I would try creating 4 partitions on 1 drive, in the following order:
/boot approx 2 g to allow for a /boot.save directory also as a backup emergency restore / (root) (however much will fit) /tmp your guess...maybe 10G swap 2.5 times your ram size
on the remaining 3 drives, create equal sized single partitions and assign them to a raid 5 MD0 array and make this /home in FSTAB
I'm interested in the outcome.
Richard, Thanks for taking the time to reply. i am beginning to suspect a hardware problem somewhere. I tried your above suggestion and got the same error when trying to create a RAID 5 array md0 mounted as /home. Drives 2,3, and 4 are all identical. At the moment they cannot be configured as a a RAID 5 array md0, whether as / or as /home. I tried to do the same thing with opensuse 10.2, which I have running on the existing server. It created a RAID 5 array md0 mounted as / with no problem on the old server, but fails on this server with the same error as 10.3. The new server is a dual core Opteron (AM2 socket). The old server is a single core Opteron, 939 socket. Don't know if that makes a difference. when the installation fails and I reboot and begin a new installation, I note that disks 3 and 4 are labeled md0, but disk 2 is not. perhaps it is a problem with disk 2. My next attempt will try to create a raid5 using disks 1, 3 and 4. Mike -- Michael A.
