10.11. Unusual Failover Behavior

A common problem with cluster servers is unusual failover behavior. Services will stop when other services start or services will refuse to start on failover. This can be due to having complex systems of failover consisting of failover domains, service dependency, and service exclusivity. Try scaling back to a simpler service or failover domain configuration and see if the issue persists. Avoid features like service exclusivity and dependency unless you fully understand how those features may effect failover under all conditions.
