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`. But then, I did try the init script but found that I couldn't connect to it so i tried the manual startup. Since that also failed I looked at the `/var/log/mongodb/mongodb.log` and found this:
**************
old lock file: /var/lib/mongodb/mongod.lock. probably means unclean shutdown
recommend removing file and running --repair
see: http://dochub.mongodb.org/core/repair for more information

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
