Promise Fastrack RAID is your culprit.
Forget using any parallel ATA RAID product made from Promise with Linux.
I've been round and round this subject, and the best they give you is
source code, but how can you build the source when there's no drive
recognized. I recommend going to 3WARE for any ATA RAID (SATA or
parallel) with Linux.
I hear that Promise SATA is supported in the kernel by default, but if
you've got what I think you've got, you're probably want to use the
on-motherboard Promise RAID chipsets. This server is best relegated to
becoming a Windows server if you want RAID with the Promise chipset.
Select your hardware carefully.....
