Grub install issue in SCSI RAID.

[dmovad]

I am trying to install ubuntu server edition 8.04 on an Intel server with an Intel motherboard SE7520AF2. This motherboard supports SCSI RAID 1 and I have 2 Fujitsu MAX3147NP 147GB u320 15K Ultra320 SCSI drives paired for installation of the operating system. After going through the install a couple of times and never being able to boot from the hard drives I tried a reinstall where I placed just the /boot partition on a SATA drive and the balance of the OS and programs on the SCSI RAID and now the system boos just fine. Note that when I had issues installing the entire OS and /boot on the SCSI RAID I also tried to reinstall grub and was never successful getting the system to boot entirely from the SCSI RAID. Now I have a working system however it seems like a half *** install with the /boot partition on a separate drive where I never intended it to be. Needless to say I'd rather have the entire OS including the /boot partition on the SCSI RAID. Note this RAID is on the Motherboard and is controlled by the BIOS (invisible to the OS).

If anyone has a clue as to why this install fails and how to fix it I'd be grateful.

Thanks...

It seems you are trying to use the BIOS fakeRAID without a driver for Ubuntu OS. This cannot work.

You might look into using a program called dmraid that would permit you to mount whatever is placed on the raid1 array, or consider this:

Good luck!

I did finally resolve the issue preventing me from having Ubuntu 8.04 successfully boot. I tried again to install Ubuntu 8.04 the other day and noted when I received the Grub error 17 that Grub was trying to boot from (hd1,0) when in fact the boot partition was on "hd0,0). Once I edited the "/boot/grub/menu.lst" and corrected the boot partition to "hd0,0" Ubuntu successfully booted. A small but very important thing to have missed on my part.

Well, it is easy to miss things when there are so many to handle to get everything just right... happy you found your problem.
