Hi again,
this is what my partitions look like:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 37748736 0 vinum # (Cyl. 0 - 2349*)
b: 2283960 37748736 swap # (Cyl. 2349*- 2491*)
c: 40032696 0 unused 0 0 # (Cyl. 0 - 2491*)
/dev/ad3
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 40032696 0 vinum # (Cyl. 0 - 2491*)
c: 40032696 0 unused 0 0 # (Cyl. 0 - 2491*)
This is my vinum.cfg:
drive d1 device /dev/ad2a
drive d2 device /dev/ad3a
# Set up volumes and mirrored plexes
volume root setupstate
plex org concat
sd length 12574720s drive d1
plex org concat
sd length 12593152s drive d2
volume root_home setupstate
plex org concat
sd length 6283264s drive d1
plex org concat
sd length 6301696s drive d2
volume var setupstate
plex org concat
sd length 6283264s drive d1
plex org concat
sd length 6301696s drive d2
volume usr setupstate
plex org concat
sd length 12574720s drive d1
plex org concat
sd length 12593152s drive d2
Here is some output from /var/log/messages after doing a vinum create:

Sep 26 19:14:11 filter /kernel: vinum: drive d1 is up

Sep 26 19:14:11 filter /kernel: vinum: usr.p0.s0 is up
Sep 26 19:14:11 filter /kernel: vinum: usr.p1.s0 is up
Sep 26 19:14:11 filter /kernel: vinum: usr.p0 is up
Sep 26 19:14:11 filter /kernel: vinum: usr is up
Everything seems fine so far.
When I do a vinum start -w, I get an error saying it can't find any vinum
drives. With the -w switch it is supposed to wait for the operation to
complete. It doesn't so I am assuming that it isn't copying the data over
from ad2 to ad3.
My problem is I don't know where to go from here. How do I get the data from
ad2 to ad3 once I have configured vinum (or have I?!?!). If I reboot my
machine at this stage, I just get a whole lot of garbage on the screen and
it justs hangs. At that stage I have been reinstalling FreeBSD4.1.
Thanks again.
Alistair.

I don't understand what you mean here.

That sounds reasonable if Vinum is already running. 'vinum start'
just goes looking for new drives.

I don't know. You should have got the same message again. You also
haven't described anything that is obviously a problem. But you
haven't really given me enough information to tell. Take a look at
vinum(4) or http://www.vinumvm.org/vinum/how-to-debug.html and give me
the information I ask for there.
Greg
