One of the odd things about the Node driver is that the default timeout for replica set connections is only 1 second, so make sure you're setting it to something more like 30s like in this example:

{ 
   options: { 
      replset: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } }, 
      server: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } } 
   } 
}

我认为他们的意思是将这些作为与 MongoClient() 一起使用的选项。
