Hi!
I checked again, and the subdisks had offsets. I have tape backups, so I
dared set up the second drive as mirror for the two plexes on the first.
After that, vinum reported quite correct all the way. Seems there might
be a bug in reporting disk size with only one drive? Not very common
setup, I guess, but it can be handy initially, to start things off.
The figures looked fine right after creating the second drive and its
plexes and subdisks, and starting them. I didn't save a copy from the
'list' command before adding a third plex, but as you can see, it looks
great now.
Oh yes: uname-> 3.2-BETA FreeBSD, May 16th. It's fresh.
Here's what I did to get it back on track:
vinum4.conf:
drive disk4 device /dev/da4s1
volume usr
plex org concat
sd length 220m drive disk4
volume local
plex org concat
sd length 4g drive disk4
create vinum4.conf
start usr.p1.s0
start local.p1.s0
Oh, another question. Shall I not be using /dev/da4s1 when issuing the
drive command? If I have a disklabel where I use some part of the disk
for ufs or swap, and have say da4s1e set up for vinum, shall I say
device /dev/da4e instead? Is that important when creating the drives? I
start vinum with 'vinum start' and it last reported
> vinum: loaded
> vinum: reading configuration from /dev/da5e
on startup. Looks fine to me ;-)
thanks for your support, and also for this fine piece of software!

PS. Here's the new list -V output:
$ vinum list -V
