Hey, I think the answer you’re looking for is already on this thread. Still, tl;dr: • If HA with embedded etcd you’ll need “odd” numbers for the control-plane quorum • If HA with external DB, just 2 should be fine.

I understand that two should cut it - we have 3 physical nodes and we would like to utilise all 3 of them - hence the question, if external db is used, are 3 nodes also ok or system “prefers” two?

I think it shouldn’t be a problem having more control planes with external DB. But I haven’t try it myself, so take my point of view with a grain of salt.

Got it - i am asking as i have tried but after deploying workload i ran into serious issues that i have not encountered before :/

How about posting the issue you are facing on the channel and call out your setup? So you can get the maintainers attention
