Well, there's your problem. You are, as the saying goes, in trouble.
Sounds like a disk/hardware/software error has hosed the superblock.
It's time to try some stuff, starting with an fsck on /dev/rwd0s3f.
the -b option to fsck is interesting; it specifies an alternate
superblock to use for the fsck. (there's supposed to be one at -b 32).
Somebody else will tell you how to restore the original superblock
from the alternate. (there are many alternates, as it happens.)
On the first pass with fsck, tell it 'no' when it asks if it should
fix things... Take your time and get a feel for what's wrong.
Run an fdisk, just to have a look at your partition table. Could another,
inferior, operating system have hosed that partition? Look for
strange partitioning, overlapping slices, anything queer.
Examine disklabel output. ANything strange?

Anybody who's run unix long enough has seen this turkey, trust me.
What does /var say when you try to mount it? To have two partitions
go south at once is a little strange, and makes me wonder what's really
wrong.
[ an aside to the list: See why I like small partitions? ]
