Mongodb

replica set

I'd like to configure replica set for development so I can use mongod on my laptop when the internet is not available and use a server hosted mongod when the internet is available.

so far...

• you need three instances so I've added a third on another host
• rs.add(host) happens on the primary, my laptop has no known url so it needs to be the primary
• before I go offline I need to run mongod on the laptop
• when I have internet, I kill mongod on the laptop causing the serverhosted db to take over as primary (by making the other secondary decline the honor)
• when the laptop mongod comes back up it takes control and gets the current data.
• rinse repeat
