I have a fully setup ubuntu 12.04 installed on a single drive and formatting it just to setup raid-1 is not an option
Unlike other answers like this one: Ubuntu 12.04 - Add RAID 1 Array on existing device?
I am trying to have a mirror of the entire disk to another secondary drive, not just a folder.
Note that the second drive is the exact same model ssd drive as the first one, and currently is empty
I would like to have a mirror drive so in case any of the two drives fail the system will continue to be working. I could not find a decent tutorial on how to do that on an already running system.
