I currently have Ubuntu 11.04 installed on a single non-RAID 160GB hard drive.
I've just bought some 500GB drives and want to end up with Ubuntu 11.04 installed on a RAID 1 array with exactly the same setup as current exists.
Can I do a clean install of Ubuntu on the RAID disks from within my current Ubuntu installation and then install packages and copy over config files etc? (In my head that doesn't sound possible, unless I can dual boot two copies of Ubuntu and could remove the current install once I was setup.)
Or even better, somehow copy my existing setup over onto the RAID array, rather than having to reinstall and set everything up again?
