I'm brand new to FreeBSD and unix for that matter. I don't think I
installed FreeBSD correctly on my hardware RAID 1. Here is my df -h

Did I screw it up? If so, is there a way to "fix" it with dd or
something? Thanks for the non-flame comments.
You should be able to fix it in /etc/fstab. Just replace ad4 with ar0.
Test it with /tmp, unmount it, replace the string in /etc/fstab and then
"mount -a". If everything is fine, there you go.
Sorry for my lack of RTFM'ing... I'm still an uber-noob. What do you
mean by "test it with /tmp"? Like umount /tmp then mount /tmp to ar0s1e?

Yes.

Go to /etc/fstab, change /dev/ad4s1e to /dev/ar0s1e.
# umount /tmp
# mount -a (or do a 'mount /dev/ad0s1e /tmp', 'mount -a' reads /etc/fstab
and checks for filesystems not mounted yet)

And if I can see the same stuff I did before the umount then I can assume
it's fixed?

If /tmp mounts fine and df -h shows /tmp mounted to your array then the rest
will do so, too.

Then change all the mounts in /etc/fstab then issue 'mount -a.' Last
question: can I do the mount -a while I'm logged in? Or would it be
better to just reboot?

Unless as you are not in single user mode you can't do a 'mount -a' on all
your file systems. So reboot. Checking with /tmp just ensures that the
machine will come up again.
