Hi Everyone 
I have a task to automate the update of a mongo replica set in Chef. The
update is minor (2.4.X to 2.4.Y) and info is available in
http://docs.mongodb.org/manual/release-notes/2.4-upgrade/. Overall as I
think I need to implement some logic in chef so that it will:
- shutdown, upgrade, start mongo slaves one by one;
- step down master, stop it, upgrade it.
Have anyone automated such case? Can you provide some examples or say what
should I watch about? I am using

BR,
Rafal.
