This, ladies and gentle geeks is what happened when I tried to start up my mongodb after an involuntary power cycle. Looking around there are plenty of posts suggesting that I should create a folder named /data/db in my hard drive. Damned if I will. Mongo db data belongs in /var/lib/mongo and in fact that's where the previously created database was placed by the system.

So why is it looking for a /data/db folder now? probably because I typed in `mongodb` at the command line instead of doing `/etc/rc.d/init.d/mongodb start`.

Pity the poor sobs who wasted their time creating directories and messing up their directory hierarchy. All your need to do is to clean up the stale lock
