Remove any old or corrupted .ns files in /data/db and then restart mongodb
I had this problem. I solved it by increasing the memory size for the replica using Virtual Box.

According to your log something is already running in mongod default port that is 27017. Just stop it and give a try.
use the following command to get the PID of the process
sudo netstat -tulnp | grep 27017
copy the PID and execute the following
sudo kill -9 <PID>
We have two collections.
So I have to delete at least one, because mongo won't restart (losing 400gb of data in the process, but that is normal when using mongo).
From this log, I cannot tell which one to delete. Is there a clue I am missing?

Our plan was to reset the databases, but we did a repair instead.
After a crash of MongoDB I currently cannot restart the database. I cleaned up the .lock file but still get the error:

when exciting mongodb with "mongod --dbpath PATH" where path is the path to the folder, where the database date shoulb be positioned.
The system runs under a virtual environment within windows.
Am new to mongodb. I have installed it on my pc with wamp server and it is working fine. Now am trying to connect with EC2 remotely.
I have gone through this . But still am not getting to connect.

[ec2-user#ip-162-31-45-45 ~]$ sudo service mongod start
Starting mongod: [FAILED]
How to solve this ?
By installing all these from This was solved my problem.
The error says that the address is already in use. Are you sure it's not already running?
Because of the size of the mongodb database I'm trying to build and because I needed a filesystem that can handle parallel writes, I moved it on a cluster that has lustreFS, which fulfills these needs.
The problem is that I can't start mongod, so I can't connect anything to the database, because mongod can't get a lock on mongod.lock. I don't have root or sudo permissions but this does not seem to be the problem here because permissions are not mentioned, as you can see:

Could you please tell me if there's any way around that lock? And no, there weren't any other mongod instances running.
Solution: File locking was being disabled by cluster admins. After file locking was enabled, mongod started and accepted connections as it should.
