However, the difference in how upstream expects to configure etcd (instance label unique) and how OpenShift configures etcd (running in pods, so instance and pod label are unique) results in the alert firing spuriously during upgrades. This means the alert fires too eagerly. The alert, once corrected, should only fire if we have reason to believe quorum is lost i.e. a majority of instances are down (must have (N+1)/2 instances up) where n is inferred from the expected number of scrape targets. The alert should have a better description and suggest possible areas to investigate, namely down control plane nodes or broken networking. A runbook addition will come later. Will be backported to 4.7 and 4.6
