It is up to software to handle errors caused by the interface going up and down and reopen sockets. Bacula could be made more cluster friendly, When you deploy bacula-fd on the cluster service then it will be a fully cluster friendly solution. I do not understand why do you suggest something different.   (which btw would also make it more robust with regards to handling network problems), It is the different problem. Yes, bacula could be a more robust regarding network problems.   but as it is, the only safe way I see to do this is to let the CRM start/stop bacula-fd dependent on the cluster IP resource. Another instance of bacula-fd can separately handle backing up any non-cluster resources on the node if needed. Yes. In real world bacula-fd can successfully handle both cluster and non-cluster resources. I've deployed a lot of real clusters this way including Linux, Unix and Windows solutions. You can ignore that, no problem. So you are running fd from init on both cluster nodes, yes? And listening on all interfaces? But only one of the nodes can be listening on the cluster IP. I can see that failover could work as long as fd on both nodes is listening on all interfaces. I don't see how this could work if fd must listen on specific interfaces and listening on all interfaces is not desired for other reasons.
