Now, I should mention at this point that I had set up a backup system last thursday that would send a report of its run to me by saving the output of Rsync to a logfile and writing that into the body of an email. When I checked the output Friday morning I noticed that there were errors regarding permissions. I figured out that the script needed to be set to run as root rather than admin (something I should have thought of right away, but alas, hindsight is 20/20 while foresight is not always as clear).
Back to this morning, while searching directories I noticed that the home share was fairly large and upon closer inspection the admin directory was the one taking up all of the room. So, a "du -h" on that directory showed that the "logs" directory inside was taking up all of the room. By this time I was beginning to realize what happened, but when I actually came accross the 40G log file (largest text file I've ever seen in my life) sitting in that directory I was still quiet dumbfounded.
So the moral of the story, I suppose, is that computers will never cease to surprise the people that work with them and to keep that in mind when troubleshooting
