Hi and thank you.
Quorum and Fencing, especially Pacemaker are known. (We will using an
2-Node-Galera Cluster for DB, and pacemaker for icingaweb Failover.)
But how is icingas handling the own implementation of HA.
Does Icinga use quorum if you're using 2 nodes?

For split-brain avoidance use could make use of SBD.

Is there any split-brain detection?
I think it's a logical impossibility for anything fewer than three nodes to
perform split-brain detection (this is not specific to Icinga).
