 I'll make that change before I reboot the system the next time.

 No, they apparently don't. But that's not the problem. The parity rewrite
 worked in the past despite this bug. And if I attempt to rebuild the
 parity now one of the disks, probably wd2, produces really alarming
 "clonk" noises. I think it is just a case of a broken disk.
