| Description |
|
When the featureCompatibilityVersion is 3.4, the config servers will return configsvr:2 in their isMaster response. This is a config server mode number that 3.2 mongos does not understand. This will prevent 3.2 mongos from connecting to the config servers, and thus will also prevent mongos from starting up against a featureCompatibilityVersion("3.4") cluster. |
