Meteor: unexpected mongo exit code 100

Question

I have just installed Meteor version 0.5.9 (45fef52095) to my CentOS release 6.3 (Final) server (Linux version 2.6.32-279.19.1.el6.i686 ([email protected]) (gcc version 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) ) #1 SMP Wed Dec 19 04:30:58 UTC 2012)

I have a samba share to a Windows SBS server mounted as /mnt/apshared under the apache user. I have created a directory inside this called 'webmeteor'. I have created an app called 'myapp' inside the 'webmeteor' directory, so my directory is like so: /mnt/apshared/webmeteor/myapp.

I am logged in as root. When I try to run the app using the meteor command, I am given the following error messages:

Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Can't start mongod

MongoDB had an unspecified uncaught exception.
Check to make sure that MongoDB is able to write to its database directory.

My first point of call was this StackOverflow question: Creating a new meteor.js file and get error 100, MongoDB not able to write -- however, following these suggestions (sudo'ing the meteor command, and checking for disk space of which I have 70GB free) has not worked. I am quite certain that these issues are permission related.

I have tried to chown recursively to root:root (as I am logged in as root), and chmod to 777 recursively also, but to no avail.

I am asking you, what should I try next, to allow my Meteor app to start?

Thanks in advance.

Answer 1

Using meteor reset erases all the data from your database. If you're worried about this then navigate to your project folder.

cd /path/to/my/project

Here you need to erase the mongodb.lock file.

rm .meteor/local/db/mongodb.lock

Now you can run Meteor using the command,

meteor

Answer 2

Removing this file and folder worked for me:

rm -rf .meteor/local/db/mongod.lock .meteor/local/db/journal/

Answer 3

Mine was fixed in the end by running export LC_ALL=C. Found the error through the debugging steps suggested in this post: https://stackoverflow.com/a/15752736/1820510
