I set up an distributed icinga2 monitoring environment with two master servers with individual MySQL DBs.
The setup seems to work, the checks are distributed between the two nodes.
I noticed if a new downtime gets created through the GUI of the first master server, it gets synchronised to the second server, but if the downtime gets deleted on the second server it won't be removed from the first server. The same happens if the downtime gets created on the second server, it won't be created on the first server.
So it seem, that the second server can not change the config on the first server. How can I make it work?
