Ah -- I'm afraid I can't do that. This server is officially in
production use now (well, it would be if it was up) and contains a lot
of valuable data. I'd be happy to back it up and try what you suggest,
but this machine is /the/ backup server...
I will note that we've had the machine running with (and booting from) a
raidz2 and a raidz1 over 6 drives, perfectly happily. It's only when we
tried to double the available space and drives that it all went a bit
pear shaped.

Hmmmm... will do. Might be next week before I can report back though.
