disk is full

[Dulmandakh Sukhbaatar]

Few days ago I installed new OBSD system, which has /, /var and /usr. 
Today I found out that /usr is not mounted and all the /usr stuffs 
installed in /. When I tried to extract src.tar.gz something was wrong. 
I have /dev/wd0d, which is not used and free. Mounted it as /usr1 and 
copied all the files and directories in /usr to it. After all umounted 
/usr1, mounted as /usr. But I can't login with new terminal. (although 
I'm not logged out). Any suggestions? Please help me.
