Unfortunately I can't get you the panic or coredump info because
this machine doesn't belong to me and is at a customer's site
right now.  See attached for the vinum_history.

It doesn't ignore it as I found out the hard way.  Unless you
'vinum create' and then change the type to vinum *after* an
unsuccessful attempt then vinum tries to "add to" the previous
configuration which is almost always guaranteed to fail.

I'd be glad to.  I only asked if the configuration I presented was
sane or had any obvious flaws.  If I still had the machine in my
possession and it wasn't seeing production use right now I'd be happy
to give you more information than you could possibly want.

'vinum resetconfig' removes all objects?  It didn't remove the
configuration information from previous failed attempts at least
for me.  If you decide to remove this functionality please explain
the proper way to "remove all objects" because every way I've tried
documented or adhoc didn't work.

What kind of dump would you like?  This machine is working happily
now and it is "live" at a customer's site but I'll do what I can
to get you whatever information you need.
