[sc:linux-category ]My previous post on OpenVPN and Failover Clustering had a happy ending, unfortunately that’s not the end of the story.
It turns out that the cluster was randomly failing between the two nodes every few minutes and the log files on the servers were filling up with errors.
I’ve been forced to disable the clustering at this point while I investigate what’s going on. The log files indicate that UCARP (the software that manages the virtual IP address between the two systems) is detecting a crash of the OpenVPN process and failing over to the other system, however the OpenVPN server doesn’t actually seem to be crashing.
A new release (1.7.1) of the OpenVPN Access Server did not help either.
I’ll have to spend some time on this, but there are other more important items on my agenda for the time being so this will take a back seat for a while.
