I am trying to expand our cluster with a second master.
First we had 1 master in master zone and 2 zones with 2 Sats each.
I already installed the second icinga2 master with a separate DB on it. I don’t want to struggle with a DB cluster right now (no time, maybe later) so in the ido config, enable_ha is set to false. This part seems to run ok. Both masters get the results as far as I can see.
But after installing Icingaweb2 on the second master, I noticed, that I have different results in both icingaweb2 views. I think, it’s because the Icingaweb2 DB is new and has not set the ACKS, which are already set in the first master. Anyway, ACKing a service on the first master, also ACKs it on the second.
So what is the best practice to install Icingaweb2 to have the same results on both masters?
I also would like to keep both icingaweb2 instances in sync to each other (including config, roles, modules etc.) How are you guys doing this?
