I'm looking for a fast to migrate Linux installation to another hardware.
As I wrote in another question (http://serverfault.com/questions/110501/unable-to-access-resume-device-in-centos), I moved 2 disks in software RAID to another hardware, and now it doesn't boot-up because the server has a SATA hardware controller not included in the initrd image. I spent a whole day trying to solve this (with the very dear mkinitrd), but still to no avail. It all probably gets complicated because I have a software raid running and the OS on top of it, and somewhere along the line it just doesn't work.
Anyway, I'm want now just to set-up a new mirrored raid, and move all the data from the old drives as fast as possible, with as least configuration as possible.
Is there a good way to do it? I heard DD should do the trick, but will it work later with the controller, or it just would overwrite all the disks and I will be back at the start?
Huge thanks in advance!
