Troubleshooting High Availability

High availability configurations can be complex, and with so many different ways to configure a failover cluster, it can be tricky to get things working properly. In this section, some common (and not so common) problems will be discussed and hopefully solved for the majority of cases. If issues are still present after consulting this section, there is a dedicated HA/CARP/VIPs board on the Netgate Forum.

Before proceeding, take the time to check all members of the HA cluster to ensure that they have consistent configura- tions. Often, it helps to walk through the example setup, double checking all of the proper settings. Repeat the process on the secondary node, and watch for any places where the configuration must be different on the secondary. Be sure to check the CARP status (Check CARP status) and ensure CARP is enabled on all cluster members.

Errors relating to HA will be logged in Status > System Logs, on the System tab. Check those logs on each system involved to see if there are any messages relating to XMLRPC sync, CARP state transitions, or other related errors.
