I am relatively new to linux and am completely dependent on these tutorials.  I bought a server and installed Suse 10.3.  After running Ubuntu on my desktop and laptop, I decided to change the server to run Ubuntu as well (I didn't uninstall Suse - just installed over it??).  After installing the server based on "The Perfect Ubuntu Server 8.04" (http://www.howtoforge.com/perfect-server-ubuntu8.04-lts) I installed the ISPConfig as detailed at the end.  Then to install RAID, I followed the tutorial perfectly I think,  but at the end of step 6 after rebooting, I still show sda1 rather than md0.

It looks different than the one in the tutorial but I attribute that to being ubuntu rather than debian.

Can anyone shed some light on this for me?  Did I miss a step or are there other steps involved because of Ubuntu?

Thanks for any help.

Jason.
