Symptoms

Assume that you use an AlwaysOn availability group (AG) in SQL Server 2017 on a Linux Pacemaker cluster. When you create the Pacemaker resource for the AG, Pacemaker demotes the current primary replica and does not promote any secondary replica to the primary. However, this issue happens only on some configurations of Pacemaker.
