Notice I have asked you to switch to single user mode before copying or 
unmounting var.
But from your prompt, I understand you are still running full multiuser, 
and of course, /var will not unmount then.
Remount /usr and issue the command:

shutdown now


to switch to single user mode. You need console access for this, do not 
attempt it remotely (unless you have a serial console) !
Then continue from the point you copy the data using the tar command. If 
you have already copied data from /var to the new partition, this may 
well be stale since /var was in use. You may wish to newfs the new 
partition again in this case.
