Mongodb service won't start

Question

I am not sure why, and the service was working fine just yesterday, all of a sudden I can not get MongoDB to start up.

[root@purr ~]# service mongod start

Answer 1

For me, the reason for not starting turned out to be an orphaned lock file at /var/lib/mongo/mongo.lock When I deleted that file, mongo would then start up OK. My system had had some messy crashes prior to this. [Fedora 14]
