Location patch Storage Node

[DJCminuz]

I am getting this error when trying to multicast, from a storage node “Failed to connect to database server, will try again in next iteration”. I have checked the /www/fog/commons/config.php to check out mysql settings. my question is do I have to modify Fog Storage node
define( “MYSQL_HOST”, “localhost” ); to

define( “MYSQL_HOST”, “Fog Main Server IP” );?
And is it the same for /opt/fog/service/etc/config.php as well. I can multicast from the main server no problem, but am trying to setup the remote nodes now. I followed install for multiple tftp server installation. Thanks
