When i go to install Ubuntu on a system with a "fakeRaid" setup I encounter a whole lot of problems. The Raid control in the BIOS has already determined the Raid level (0). So when go to install Ubuntu it sees the 2 HDDs as 1. I tried to follow the directions given in the fake Raid install on the help page but there are 2 instances that are not described. First I get a message from Ubuntu that it has detected the Raid on a Serial ATA device and also the separate drives are recognized as one.

Following the directions on the help page states that I should see 2 HDDs and not the 1?

I am trying to install Ubuntu 10.04 LTS (Lucid Lynx). I have a Dell XPS410 running an Intel core 2 processor, 2 W.D. HDDs 250 g a piece and an NVIDIA GEforce vid card.

I have no idea what I am doing or if a manual exists?

Thank you very much in advance.

so what is the error? if ubuntu recognizes it as a raid then everything is good, I have done this and just install to the raid setup, not the individual drives.

cheers

cheersWhen i do what the instructions indicate that I should it creates a space for the / and swap, I then go to the / partition and indicate that it should be a bootable flag. But, then I cannot do this too the other drive as well. Just as the instructions indicate that I should. Even when I try to bypass the above steps i get an error message that the ext4 file system creation failed and it won't let me continue the installation.

Is there a step that I should take after Ubuntu recognizes the Raid setup? I can't find a guide. i also tried to just install it from the regular CD and not the alternate and I get the same message (ext 4 file system error).

Thanks for replying Ready Carpenter!!

It seems you need to install something called mdadm.

Please have a close look at the guide here (http://ubuntuforums.org/showthread.php?t=408461)

Also note that you are using the Desktop Live CD, not the alternate install CD.

Be careful!

in previous version of ubuntu it would not see the raid array properly. those instructions are outdated for Ubuntu 10.04. One of the new features of Ubuntu 10.04 is the ability to see and install on fakeraid volumes.

are you planning on installing windows on the fakeraid volume as well? If you are just doing linux, you should consider setting up the raid in linux instead of in the bios.

I have the Alternate CD as well. I just haven't the foggiest what to do next.

should i use the alternate versus the Live CD? and then what after?

Thanks for all the help insofar!
