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
St         


        

Answer 1

It's all in your error message - seems like unclean shutdown was detected. See http://docs.mongodb.org/manual/tutorial/recover-data-following-unexpected-shutdown/ for detailed information.

In my expirience, usually it helps to run mongod.exe with --repair option ro repair DB.
