How to enable the server clustered?

Question

Hi,

I designate a server as a primary server, and the CompleteFTP manager connected to that server. But as I want to add another server (secondary), it not synchronized with the primary server. 

How to make both (primary and secondary) server in enable state? how to enable server clustering?

The secondary's configuration should get overwritten by the primary immediately as it's added.  If there's an error during this process then it should be in the logs.  A good place to start would be to enable real-time logging, add the secondary and then check for errors in the log view.
