Hi Guys,
I’m curious: Has anyone setup an Icinga High-Availability-Cluster with more than 2 Active Master nodes? Does that even work? All Documentation is just about 2 Master-Servers but what if I want more?
Documentation is only for two masters because it does not work for more. This is an outstanding bug in the cluster communication which was not easy to solve so support was limited to two until it got fixed, but as far as I know no work has gone into fixing it yet.
Yeah, i confirm that, you have the related github ticket here :
With this solved it would allow a much better scaling in my opinion, but i guess it would also introduce other limitations.
I will mark Dirks answer as the solution, as I feel like it resolves the topic
