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.
