IcingaDB on every master?

Icinga DB
1

Hi,

we followed the https://icinga.com/blog/2020/10/01/how-to-set-up-high-availability-masters/ guide to add a second master to our environment.

Can the IcingaDB component safely run on both master nodes or should their only be one active IcingaDB service? Is some additional configuration required for HA? I only could find IDO HA guides…

Thanks Markus
