To find out if csyncd is operational, proceed as follows:

1. Browse HAProxy ALOHA web UI and open the Setup tab.

2. Look for the Remote Configuration area.

3. The Current status table reports the synchronization capability of the cluster:

   • A red LED means synchronization does not work.
   • An orange LED or a green LED means synchronization is operational.

If the LED is red, run the steps below to troubleshoot:

• Power on both HAProxy ALOHA appliances.
• Check that both HAProxy ALOHA web UIs listen on the same TCP port and on the same protocol scheme (HTTP or HTTPs).
• Check that both HAProxy ALOHA appliances can ping each other.
• Verify that csyncd service is started on both HAProxy ALOHA appliances, i.e. green LED in the Services tab.
• Force a csyncd key exchange.
