Hello Martin
We encountered a similar issue in with a client I had and the solution
we decided to use was a MariaDB Galera Cluster,
It allows a full replication and give you master election in case of
node failure.

Hello,
some time ago I've been asking here for some details about
implementing HA for Icinga2 master server.
I need two master servers, one is located in Europe, the second one in US.
The concern I have is the database server, I'd really like to have
dedicated database server for both master server geographical location.
So I did, I habe two DB servers and these two are configured for
master-master replication.
That works. Now, how Icinga handle that?
When I configured each Icinga2 instance to use its database server, I
immediatelly got "duplicate items" error and deadlocks.
Now I have restored the database and pointed both icinga masters to
the same database, but everything is now doubled, checks, hosts…oops,
that's different problem I guess.
So, my question is, is there anybody with similar scenario? The icinga
database replicated?
What the "instane_name" from IdoMySqlConnection object does?

Any hints, please?
Thanks for help!
