Problems partitioning and mounting vnode filesystem(s)

[John Fox]

Hello, all.

I'm having a bit of a problem working with a vnode filesystem, and
have finally hit the point where I ask for help. :)

The intent was to create a large vn-filesystem and break it into four 
partitions, for mounting within a jail.

DEVICE               SIZE (approx.)     
vn0a                  500MB
vn0d                 1000MB
vn0e                 1000MB
vn0f                 2500MB

It seemed to go well; I configured a file for use as vn filesystem,
and edited its disklabel (see below) to get the partitions I wanted
with no problems.

But I ran into a problem -- the system appears to recognize only the 
500MB partition, regardless of which is mounted (see below, after
the disk label).

I *could* just do this by creating vn0, vn1, vn2, and vn3, I guess, but
I want to know what I'm doing wrong.

I took a look in this machines '/dev' directory, and saw that there
exists  "/dev/vn0s1a" through "/dev/vn0s1f".  Should I be using these
's1' devices?

I'm very excited about using these vnode fileystems, so I'll be 
very appreciative of any advice!

Thank you,
