NOTE:   All distributions (including RHEL 7.4) that use the latest available pacemaker package 1.1.18-11.el7 has a known issue that affects failover workflow. If primary replica experiences an outage, the cluster is expected to failover to one of the available secondary replicas. Instead, users will notice that the cluster keeps trying to start the failed primary replica. If that primary never comes online (due to a permanent outage) the cluster never fails over to another available secondary replica.

  • This issue affects all SQL Server versions, irrespective of the Cumulative Update version they are on.
  • To mitigate the issue, user must revert back to Pacemaker version 1.1.16.
