We create a new meteor.js file and get an error of 100, MongoDB cannot write

Question

I play 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 fix this, especially in the context of Meteor.js I installed using curl in the background of a snow leopard.

It actually worked for a while, when I did a few exercises from a book that I have, and then he overcame a mistake. Not sure what I did.

Answer 1

As in our discussion, you just need to free up disk space, I want the meteor to give more descriptive errors.

If you free up some space, it should sort out

Answer 2

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

Answer 3

I had this problem when I upgraded from 0.7 to 0.8 in my local environment, I had nothing to lose in my local database, so I fixed:

 rm -rf .meteor/local/db 

Answer 4

You may already have a mongod instance, do

 ps -el | grep mongo 

and if he starts it and restarts

Answer 5

As @Akshat said:

If you can't even root a meteorite, this is probably the full partion, and you should clear or just move the folder to another partition.

If you can run meteor as root, this is probably a rights issue solvable this way:
In the meteor project folder: sudo chown -R $USER:$USER .
I recommend that you do not use the NTFS partition, since it is difficult to set the correct rights there.
