Pull Request (PR) description
rs.slaveOk has been deprecated since version 3.6.20 and others. Warnings are all over the place e.g.
in the mongodb_is_master fact. Which makes the fact and
/root/.mongrc.jsunusable.Using a try-catch block to use the new command rs.secondaryOK() by default and fall back to rs.slaveOK() fixes this.
