My boot drive is a 2-drive RAID-1 volume created with RST and it is working fine. I want to do an Operating System (OS) upgrade but before I want to keep one of the drives as a "backup drive". If everything goes Ok with the upgrade I want to rebuild the RAID-1 overwriting the "backup drive" (old OS) with the data in the other drive (new OS). If things don't go Ok I would like to rebuild the RAID-1 overwritting the other drive (new OS) with the content of the "backup drive" (old OS). What are the correct steps I need to follow for this?
Thanks,
Rafael.
