MongoDb won't start

Question

I went to restart my mongo db because I realized that I did not have auth=true set in my mongo.conf file.

I've never had problems restarting before.

I restarted by sudo /etc/init.d/mongo restart.

It failed to restarted.

When I look in the mongo.log file I see some errors. The folder that it is complaining about is owned by root and not mongod . I actually see about 5 folders that are owned by root in the data folder.

Is this normal? Can I just change the permissions on this folder to mongod?

Yes, you can change the permissions for the data folder safely

sudo chown -R mongod:mongod /var/lib/mongodb 

...or whatever DB path you have set. I also had to do it recently, because my MongoDB server crashed, and I had to repair. But the repaired files were created with wrong permissions
