After not getting any feedback, I decided to do

fsck -y

This returned my machine to usable. Before doing this while I was  
just hitting "y" to the questions I did not understand, one of them  
mentioned that it had to create a lost+found directory and after a  
while that the directory was out of space. It asked me the question  
to expand. So, I hit yes. Anyways, after all is said and done, that  
filesystem has 500MB of more free space than it did before (it  
doesn't take into account the fact that /usr/src is now empty and the  
size of lost+found). What does the expand option do? Can I safely  
delete lost+found? Like I mentioned before, this is my first time in  
going through these types of issues and I have not found any  
documentation that I can fully understand on fsck and what it does.  
In any event, thank you all for your assistance.
