> The word JournalNode in this markdown file is incorrect spelled.
> In order for the Standby node to keep its state synchronized with the Active 
> node, both nodes communicate with a group of separate daemons called 
> "JournalNodes" (JNs). When any namespace modification is performed by the 
> Active node, it durably logs a record of the modification to a majority of 
> these JNs. The Standby node is capable of reading the edits from the JNs, and 
> is constantly watching them for changes to the edit log. As the Standby Node 
> sees the edits, it applies them to its own namespace. In the event of a 
> failover, the Standby will ensure that it has read all of the edits from the 
> {color:#333333}*JounalNodes*{color} before promoting itself to the Active 
> state. This ensures that the namespace state is fully synchronized before a 
> failover occurs.
