On this page

Follow these steps to troubleshoot a cluster of HAProxy ALOHA instances.

Csyncd Jump to heading

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.
