I’m getting the following error:

alex@alex-K43U:/$ mongo
MongoDB shell version: 2.2.0
connecting to: test
Thu Oct 11 11:46:53 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
exception: connect failed
alex@alex-K43U:/$

This is what happens when I try to start mongodb:

* Starting database mongodb                                             [fail]

I already tried mongo --repair

I made chown and chmod to var, lib, and data/db and log mongodb.

Not sure what else to do. Any suggestions?

mongodb.log:

***** SERVER RESTARTED *****

EDIT:

I removed the lock then did mongod repair and got this error:

Thu Oct 11 12:05:37 [initandlisten] exception in initAndListen: 10309 Unable to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating

so I did it with sudo:

alex@alex-K43U:~$ sudo mongod --repair

    The log indicates that mongodb is terminating because there is an old lock file.

    If you are not and were not running with journaling, remove the lock file, run repair, and start mongodb again.

    If you are or were running with journaling turned on, see the relevant Mongo DB docs. Note that they say “If you are running with Journaling you should not do a repair to recover to a consistent state.” So if you were journaling, the repair may have made things worse.
