Ok, I think my only choice at this point is to delete and recreate the RAID, then restore from backup (oy, 7TB).

I see that I can do an mdadm –remove /dev/md0, then, the page I see that on, suggests zeroing the superblocks. What would happen if I *don’t* zero the superblocks before doing an mdadm –create? Would I just wind up back where I am?
