Creating a new meteor.js file and get error 100, MongoDB not able to write

Question

I'm playing with meteor.js and I get this error:

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.

I'm not sure how to remedy this, especially within the context of Meteor.js I installed using curl on snow leopard mac os.

It was actually working for a while as I did a few exercises from a book I have, then it conked out with the error. Not sure what I did.

Answer 1

I fixed this by going to .meteor\local\db and deleting mongod.lock

Answer 2

I had this problem when I updated from 0.7 to 0.8 in my local environment, I had nothing to loose in my local database, so I fixed by:

rm -rf .meteor/local/db

Answer 3

As with our discussion, you just need to free up some disk space, I wish meteor would give more descriptive errors.

If you free up some space it should sort itself out
