March 31, 201214 yr Can I add disks from a previous built in my current server without formatting them and data loss? I have some disks from my first unraid build with 1 TB of downloaded stuff on it. Can I just put these in empty slots on my current server and add them to the array without formatting them?

Stop the array Set a new disk configuration (different methods, depending on your version of unRAID) assign the disks Start the array
March 31, 201214 yr Author Thanks Joe. Is this new disk configuration save for my current array? I'm on 5b12a at the moment.
March 31, 201214 yr I would recemend a parity check before you stop the old array. just to make sure everything is OK.
March 31, 201214 yr Thanks Joe. Is this new disk configuration save for my current array? I'm on 5b12a at the moment. Yes... A new disk configuration will not affect existing disks. It is the one time existing disks properly formatted with unRAID data will be added without clearing/formatting them first. Setting a new disk configuration immediately invalidates parity. so as already advised, before you do anything, run a non-correcting parity check. If your version of unRAID does not have a non-corrrecting option, run the command from the linux command line instead /root/mdcmd check NOCORRECT Type exactly as above. capitalization is important.
