December 10, 20214 yr So I recently moved. Prior to the move I upgraded my 4TB drives to newer 10 drives. Ran a parity check and packed everything up for the move. During the move I somehow lost my unRaid USB thumb drive. I have plenty of USB sticks laying around, so i grabbed one formatted following the proceedure to create a new boot drive, using an old backup file I had thought I created after the drive swap. Started up the array, and it is showing all my old 4TB drives as missing. So obviously my backup file dated after I did the swap, was older than I had thought. I don't really care about the time it will take to rebuild parity, so my question is, can I just perform a new config and let parity rebuild without loosing any data? If so does it matter what slots I use for the drives? Do I need to retain the old drive order? Thanks in advance for any advice.

Yes, as long as you don't assign a data drive to a parity slot, if you now which one is parity it's a simple process, with single parity drive order doesn't matter so you can even check parity is already valid before array start, should still run a parity check after to make sure all is well.
December 10, 20214 yr Author Thank you for the quick response. That makes me feel a lot better. Fortunately I know the serial number for the parity drive. When I do the new config, do I want to preserve the assignments, or would it be better not to if I don't know the order? Again thanks for all the help!

December 10, 20214 yr Community Expert Note that any other changes to your configuration since that flash backup are also gone. Any settings you made in the webUI, including docker installs.
December 11, 20214 yr Author Thanks for pointing out the other configuration items! I'm OK with rebuilding everything back as long as my data stays intact.
