This repo contains a bit of code to help with testing ruby mongo driver retries.

Each sub directory contains test code for a different set of drivers and approaches... It's all pretty hacky so, ymmv.

Mongo Replication Set Setup

Taken from: http://www.mongodb.org/display/DOCS/Replica+Set+Tutorial

On my Mac:

Create the data directories for the reply set:

    mkdir -p /usr/local/var/mongo_repl/r0
    mkdir -p /usr/local/var/mongo_repl/r1
    mkdir -p /usr/local/var/mongo_repl/r2

Then start up each instance:

    mongod --replSet repl_set --port 27017 --dbpath /usr/local/var/mongo_repl/r0
    mongod --replSet repl_set --port 27018 --dbpath /usr/local/var/mongo_repl/r1
    mongod --replSet repl_set --port 27019 --dbpath /usr/local/var/mongo_repl/r2

Initialize the set:

    bash$ mongo localhost:27017
    mongo > config = {_id: 'repl_set', members: [
                     {_id: 0, host: 'localhost:27017'},
                 {_id: 1, host: 'localhost:27018'},
                 {_id: 2, host: 'localhost:27019'}] 
                          } 
    mongo > rs.initiate(config);

Check the sets status with:

    mongo > rs.status()

Wait until every member has health 1. All members should be in state 2 except for one member that is in state 1
