I don't think there is a good answer to your question *as asked*,
so we just have to come up with a new question and solve your
problem. :)

I am GUESSING your real problem is "I didn't make /var big enough"
You can add a second disk. And you did.

I would look closely at what partitions you have on /dev/sd1c.

Got a /home? Move that to your second drive, move the /var to your
old /home.

Or..what is the real problem with /var? Maybe /var/www? Move
THAT to your second drive, leave /var (which is kinda important on
boot for a lot of reasons!) on sd1. But in general, work out a
way to keep /var on your primary boot drive, and put something
that isn't needed in the first moments of boot on the secondary
drive. Some other ideas that could be moved:
/usr/local
/usr/src
/usr/bin
/usr/ports
/home
Most of those would provide a good basic /var

If you over-built some other partition, copy the data off, make it
smaller, reload, and use the freed space for a /var.
