// Test basic replication functionality

// There is no automatic fail-over in a master/slave deployment, so if the master goes down, no new
|
|
// master will be elected. Therefore if the master is using an ephemeral storage engine, it cannot
|
|
// be restarted without losing all data. This test expects that restarting the master will maintain
|
|
// the node's data, so cannot be run with ephemeral storage engines.
