mongoid - Moped::Errors::ConnectionFailure Could not connect to any secondary or primary nodes for replica set

Question

I had to forcefully shutdown my Ubuntu system after it got hanged. Now I get this error while trying to run my Rails app.

Moped::Errors::ConnectionFailure (Could not connect to any secondary or primary nodes for replica set <Moped::Cluster nodes=[<Moped::Node resolved_address="127.0.0.1:27017">]>):

Im using Rails 3.2.11 with Mongoid 3.1.4.

What could be wrong?

Answer 1

I was able to get it working by removing the mongod.lock file and restarting mongodb service

sudo rm /var/lib/mongodb/mongod.lock
sudo service mongodb start
