I have a concatenated 2 drives together to make 1 large disk using

I wish to move my vinum disks to another computer, but I really don't
want to lose any information. So I want to ask from someone who has
done this, instead of just trusting myself to read the manpage
correctly. Don't get me wrong, I have read the manpage, but if I lose
this data I will kick myself, hard. Unfortunately I don't have enough
storage space anywhere else to do a full backup...
my vinum config is this:
drive d1 device /dev/ad2s1e
drive d2 device /dev/ad3s1e
volume tank
plex org concat
sd length 0 drive d1
sd length 0 drive d2
This isn't important.
To complicate matters, I wish to add another drive, but from what I
understand I cannot add another drive without reformatting all of
them, correct?
Incorrect.
It's always better to make a backup, and there's always the danger
that something will go wrong when you rebuild hardware, but basically
this is what you need to do:
1. Put the disks in the system, anywhere.
2. Start the system.
3. Start Vinum.
Your data should be found automatically. It's a good idea to do an
fsck -n on the data to make sure it's OK. Make sure you use the -n
option; if you do find a way to confuse Vinum, it will be very
confused, and you don't want to write anything back to the volume
until you're sure Vinum knows what it's doing.
