I have a rails-app which uses both mongoid and mongo. I use mongoid for my own models, and I use mongo because I have ruote with a ruote-mon storage.

In production however; I get

Mongo::ConnectionFailure: Failed to connect to a master node at localhost:27017

when I try to connect to the ruote storage. Even when I just do Mongo::MongoClient.new

Steps I have taken so far to try to resolve this:

  1. I have made my mongodb an explicit master by setting master = true in /etc/mongod.conf

  2. There are no $ENV variables set that could intervene with Mongo::MongoClient.new (double checked)

  3. I have tried to connect using Mongo::MongoClient.new(:slave_ok => true) – same error

  4. I have restarted my mongo database several times (w/o success).

  5. I have checked my firewall settings and I can connect to localhost:27017 with telnet (as said, the mongoid documents can be fetched and stored w/o issue)

I am out of my wits… Any suggestions?

    please look at: https://jira.mongodb.org/browse/RUBY-525

    Should be fixed by the 1.8.2 mongo gem.
