Hello,

I am looking for advice on doing some disc shuffling. Right now, my unraid server has a 10TB Parity drive, 4x4TB data drive and 1x10TB data drive. Unfortunately the 10TB data drive has died (tough). Not the end of the world though because I was starting to run low on space and I found a good deal on a 22TB and an 18TB drive which I impulsively purchased without thinking about it.

My goal is to put the 22TB drive as the new parity disc, add the 18TB as a data drive and move the 10TB parity disc to be a data disc. How do I accomplish this without loosing my data that was on the dead disc? What makes most sense to me would be to direct copy my 10TB parity to the 22TB parity then wipe the 10TB and use it to replace the dead 10TB parity but I am not sure if thats possible with a dead drive? Otherwise it seems like I would have to partition the 18TB to be 10TB in order to recover the data on the dead parity then rebuild parity on the 22TB and then add the 10TB and remove the partition on the 18TB and recover all the data. Seems like a crazy pain that would take a long time.

I appreciate any suggestions.

You can do a parity swap then add the 18TB as a new data dusk.

Oh awesome! I had seen that before but was just concerned that it wouldn't work with a failed disc (didn't read closely enough). Thanks for the help!
