Comment 10 for bug 568050

I've tried to install 10.04 RC on an nVidia RAID5 (fakeraid using dmraid) via alternate and main install and both fail to load any dmraid drivers at all (none - not even RAID0/1). dmraid seems to be completely broken in the RC - the installer offers to activate it but nothing is detected afterwards and a manual attempt reports missing modules. Also, as per previous Ubuntu versions, the dmraid-activate seems to mess up the raid45 driver stuff anyway - I always have the manually install the modules during installation and then edit dmraid-activate to change the module load to dm-raid4-5 and the rebuild the initrd before rebooting otherwise the install is messed up. There are various past bug reports on this so I'm not going to repeat them as it's been reported enough times already without me duplicating it further.

I saw one posting (elsewhere) suggesting just using software raid - while that's probably a fair suggestion, the dmraid really should work when it is detecting the fakeraid controller is there and offering it.
