OK. If you are using Rails + MongoID and you get this error message here:
read_secondary options has now been deprecated and will be removed in driver v2.0. Use the :read option instead.
Than you just have to change your configuration. Just replace “read_secondary” with “read”.

And one more thing. “read” is not true or false. Valid values for “read” are “:primary” and “:secondary”.
