October 12, 20214 yr I have 4 drives, all 4TB. One of the disks I guess had/has problems and was sitting "unassigned". I shut down, pulled it out, popped in a new one, then stopped the array, set it as a 4th data disk by mistake, started array and saw 16tb available, realised my mistake, stopped array. Now the only valid configuration is to boot up with a 0 parity 4 disk array. What's the best way to proceed? I'm guessing I have to boot this array and follow a procedure for "downscaling" an array, then remove the 4th disk and hopefully get it back to unassigned?
October 12, 20214 yr What you could do is: Go to Tools -> New Config and use the option to retain all current assignments Return to the Main tab and move the disk mentioned from being a data drive to a parity drive. Start the array to commit the new assignments and build parity based on the assigned data disks. The array will show as unprotected until the parity build completes.

Thanks, that was pretty easy/quick and and it seems to be rebuilding etc fine now.
