Hardward Raid Issues

Post by Todd_Z »

I just put together a system, and bought 4 320 gig harddrives. My plan is to use RAID 0+1 via the hardware raid control on the mobo. When i go into the raid utitlity, after setting up the sata drives as raid in the bios, i set up the raid and it says its healthy. I pop in a live/install cd of ubuntu and when i go to install, there are 4 drives available. There should be one. Right?

Any ideas?

Have you read this How-To?

SATA RAID How-to
Ubuntu (and Debian) doesn't have support for the SATA RAID (also called FakeRAID since some of the functionality is provided by software) controllers being shipped on recent motherboards (The only distros to support these currently are Gentoo and Fedora Core 5). The software to handle FakeRAID arrays in Linux is dmraid. Dmraid is currently not integrated into the Debian installer or the Ubuntu Live-CD installer. Therefore, one cannot directly install Ubuntu onto such RAID arrays. Previously, one had to install Ubuntu on to a separate partition and then debootstrap Ubuntu. However the Dapper Live-CD can be used to easily install Ubuntu Dapper onto such RAID arrays.

I am still plugging away on this. I have been having a lot of trouble.

I dont know if it is because I'm doing a 0+1 configuration.

I was contemplating getting a true hardware raid card.
3ware 9550SX-4LP ~ $310

My MoBo: Asus m2n-SLI Deluxe

I can't tell if the raid card will be compatible - it looks like its a 64 bit PCI card, whereas the mobo has 32 bit - does anyone know if they are backwards compat?
