After finishing some long drive consolidation procedures (replacing lots of smaller drives with fewer larger ones) I've come to a point where I would like to arrange the disks in the array to better correspond to their physical location in the tower. I have tried following the instruction on the wiki but upon reassignment to different slots, I'm getting the following screen:

I'm inclined at this stage to follow the Trust My Array procedure described here but reading the warnings, it mentions that no drives should be marked as disabled or missing. Maybe I'm misreading this and I though't I'd better ask first if it safe to ignore the missing marked disks as long as they are reassigned to different slots?

 

Thanks!

You can only swap 2 existing drives at a time. You can't swap drives into empty slots. You'll have to do an initialization and build parity.

 

In theory you could do the trust my parity since the data disks are just being arranged which doesn't change parity. But it doesn't really matter. You could just start the parity build and cancel right after and then start a non-correcting check if you were so inclined.

I ended up doing the Trust Parity procedure which validated it immediately. A parity check and 7 hours later, everything is OK
