Barracuda Load Balancer

How to Remove a Barracuda Load Balancer from a High Availability Environment

  • Last updated on

If you are running firmware version or earlier you must manually delete the service virtual interfaces and any custom virtual interfaces from the system you are removing from the cluster.

Remove a System from a Cluster

On the Barracuda Load Balancer to be removed from the cluster, perform the following steps:

  1. On the ADVANCED > High Availability page, clear the Cluster Shared Secret to remove the Barracuda Load Balancer from the cluster. You are automatically logged out of the web interface; log back into the system.

  2. On the ADVANCED > High Availability page, click the Trash icon to delete the other system from the Clustered Systems table; you must perform this action on both systems in the cluster.
  3. If the systems are in two-arm Route-Path mode, go to the BASIC > IP Configuration page and manually clear the LAN IP Address to prevent any IP conflicts with the peer system, and then click Save Changes.
  4. The peer system should now be standalone and active with its configuration intact; this device is now standalone but without any virtual interfaces.
