Greg, et al.
Thanks for all the responses.
Here is a status update. I have made an important discovery. I now
load load vinum via loader.conf as recommended (but not yet required)
by the vinum document. My vinum on my ide drives now seems to load
just fine. I will be doing some stress testing today.
So, the problem I reported seems to letting vinum load via rc.conf
and the /etc/rc.d/vinum script.
