OK, more info now that I am at the console of the machine again.

During the weekend I discovered that I had saved a copy of my previously
working kernel somewhere in my homedirectory, so this morning I first compiled
a Feb 6 version of /sbin/vinum, and then booted off the old kernel + vinum
module, and executed the old /sbin/vinum. No error message, but the only
things listed in my configuration were the drives (so no
volumes/plexes/subdisks).

Next up I tried your suggestion above with my new kernel. This also got rid of
the error message (or at least it doesn't show up), but again the only objects
listed were the drives; no volumes etc.

My current theory is that I somehow goofed up during the kernel rebuild-a-thon
last friday, and that I somewhere loaded the old vinum module alongside the
new kernel; and this bit me by overwriting my configuration. It's the only
explanation I can think of (since I'm obviously the only one to have this
problem). If you want more information or have more things I could try
I'd be glad to do so, but I think that it was me that introduced this, altough
I couldn't for the life of me think of anything I did that could cause this.

Although the data that was on the volume is not crucial, it would be nice if
there was a way to recover it; so if you don't want to investigate further,
can you tell me whether a vinum create would restore my volumes, or is there
simply no way that I can do so without obliterating the data? If the latter,
I'll just move on and recreate the plex using ccd(4) (seeing as following
vinum development is not one of my goals right now).
