Actually I've never heard of gvinum, so I'm pretty sure we're looking
at vinum here.

Looks like this is an odd pilot error. If I label disks from within
sysinstall and on the command line, one tool apparently doesn't know
what the other is doing. This must be a gross misunderstanding on my
side of how these tools work. Using bsdlabel to set the partition
sizes apparently is not sufficient. To make a long story short, I went
back to sysinstall, created a partition using the full disk, then went
to bsdlabel -e to turn the partition into type vinum. Now I get the
full capacity.

I still can't make a raid5 out of these drives. I'm still fiddling and
will get back to the list if I can't figure this out myself.

Thanks anyway for your prompt answer.
