Version 2.67 of MongoDB is installed. When I run MongoD in Terminal (mac os x 10.95), here is the message I get. (BTW, I have tried Sudo)![Error][1]

If it is the first time you are running MongoDB, make sure you have you have owner permission to create mongod.lock file to create in /data/db path.
sudo chown -R `id -u` /data/db
first try:
mongo localhost
to see if there already a mongod instance running. if not, you should delete the mongod.lock
sudo rm /data/db/mongod.lock
if means you had an unclear shutdown of mongod.
Important: this assumes you don't have anything important in the DB because it seems it's running on your macbook air.

This is the error I get after starting mongodb. I have the /data/db directory setup. any suggestions? Thank you.

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>
I have followed the instructions on MongoDB's website to install MongoDB on RHEL systems. Whenever I use the command sudo service mongod start I get the message Starting mongod: [FAILED]. Does anyone know what I am doing wrong? I already changed the permissions to the /var/lib/mongo and /var/log/mongodb directories.
In addition, this is what my log file reads for the last time I tried to start mongoDB

that looks very similar to the output when you have a mongo already running.
probably you have a startup script installed in /etc/init.d/mongod
Your log file is clipped. Please include an unclipped version where we can see the entire line. From what's there, mongod couldn't lock something, which likely means you already have a mongod running in that directory or the permissions aren't set to allow mongod to take the lock.
I installed mongodb using the information in this link. However, when I user the service mongod start command I get the following error. Can someone help me troubleshoot?
[Piyush#localhost ~]$ service mongod start

I tried using --repair command. I get the following output for that:

The --repair flag is meant to repair a corrupt database, not to solve any permission problems
You obviously didn't follow the instructions of the link too closely, because he did start the service as root. ;) sudo may only allow certain parts of the init scripts to be executed with superuser rights by the user calling it. Others may (though they shouldn't) silently fail. As for init scripts at least: sudo != being root.
To fix the problem: sudo chown mongod -R /var/log/mongodb/ && sudo chown mongod -R /var/run/mongodb && sudo chown mongod -R /var/lib/mongo Then become root and try to run mongo manually with sudo -u mongod mongod --dbpath /var/lib/mongo --logpath /var/log/mongodb/mongod.log. In case there are other problems left, mongodb will tell you. Fix those until starting mongodb manually as written above works flawless, then use the initscript from that point on.
Edit: corrected the --dbpath option as per comment
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.

➜ ~ mongo --version
MongoDB shell version: 2.6.0
but if i do this:
> use foo
switched to db foo
> use foo
switched to db foo
> foo.version()

How can I clean my double Installation?
I want 2.6.0
#monkeyUser,
Running two different MongoDB instances is not an issue per-se provided they use different data directories. In your case, looks like you have two MongoDB installation with same data directory configured for both. If you intend to keep both the instances you'll need to change the dbPath for one of them to point at some other directory.
If you do not intend to run two instances and only the latest instance, uninstall the previously installed instance using same steps from the blog post but executing them in reverse order (bottom up) and in inverted sense i.e. if blog has a step to create a directory /data/db, you would execute this steps as "deleting the data directory /data/db". Once you have removed one of the instances, second instances should come up fine.
