mongodb.lock permission denied

mongodb archlinux

I verified /etc/rc.d/mongodb, and I think it will use mongodb user to run the service:

[ -z "$PID" ] && /bin/su mongodb -c "/usr/bin/mongod --config /etc/mongodb.conf --fork" > /dev/null

I think this error may caused by run mongod using root, so the owner of the mongod.lock is changed to root.

I can start a MongoDB instance by mongod, but not in the background as above

When you start mongod this way are you actually starting it with all of the same parameters? The lock file is only for that specific folder.

Things to check:

Is there already an instance of mongod running (ps -ef | grep mongod)?
Is there something else running on that port?
Are you configs correct? Why do you have the --journal command, shouldn't this be --nojournal in v2.0+ or simply nothing?
