I wrestled with installation of ubuntu on my two 500GB SATA fake raid 0 disks for weeks now.
Hardware: ASUS P5N-E SLI (nForce 650 chipset)with newest BIOS, two Seagate Barracuda 7200.12 500GB disks in (nv)RAID 0, three partitions - 40GB Windows 7 x64 C: drive, ~900GB Windows D: drive, 8GB empty/ext4)
Here's the results (all distros are amd64 both live and alternate were tried):
Ubuntu 8.04 LTS, 8.10, 9.04, 9.10, 10.04 alpha - not working
Debian 5.04 - not working
Fedora 12 - works like charm (but for me it's a ****** distro either)
All distros uses dmraid to map disks. Problem is, that depending of Ubuntu/Debian version they see only one empty physical disk or two separate empty physical disks (/dev/sda and/or /dev/sdb)and after messing with dmraid in the console - empty fake raid disk (/dev/mapper/nvidia_ifgafbij) with size equal to only one physical drive, 500GB instead of 1TB in my case AND /dev/sdx at the same time (even with dmraid -ay -Z).
Fedora maps disks perfectly using dmraid even in graphical installer (nvidia_ifgafbij - disk, nvidia_ifgafbij1 - windows C partition, nvidia_ifgafbij2 - windows D partition, nvidia_ifgafbij3 ext4 partition). Even bootmanager (guess it was LILO, I didn't bother to check) was installed without a hitch.
Fedora proves that it is possible to make RAID-friendly distro. Why so great distro like Ubuntu can't take the example from Fedora and fix RAID issues already?
