RAID array on Promise FastTrak detected as separate drives
When installing Ubuntu Server i386 via CD-ROM, my RAID 2+0 array is not detected as 1 drive, but as two separate drives. These are 2 IDE drives attached. This also results in GRUB failing to boot after the installer is complete.
The RAID controller is a Promise FastTrak133 (PDC20277) which is onboard an Intel SE7501WV2 server motherboard.
lspci reports the following about my controller:
01:02.0 RAID bus Controller: Promise Technology, Inc. PDC20277 (SBFastTrak133t
I suspect this bug belongs in the kernel, but I am not intimately familar with Ubuntu's package structure. I am also not sure how to proceed debugging this issue since my experience with RAID has mainly been plug and play. I am willing to debug if someone can provide me with instructions.
I also tried this on hardy rc5 and got the same result.
