The original layout had two drives,  one volume, four plexes, eight
subdisks.  I actually wanted four volumes, two plexes with one subdisk on
each disk per volume.

As an aside - The vinunm manpage needs to be broken into (at least) two
pages, the second page being strictly a configuration file page.  A casual
(or not so casual read) of the existing manpage doesn't explicitly state how
you configure a mirrored volume -- or more precise, what in a configuration
MAKES a pair of plexes mirrored.  This omission is severe.

I know I shouldn't use resetconfig.  But I couldn't use rm either, because I
couldn't shutdown the items I wanted to rm.  I refused to use force because
it should not have been needed on a clean configuration.

rm commands at all object levels and detach commands.  All gave generic
"device busy errors",
