Either approach is reasonable. The advantages of keeping them in pacemaker are: - Service-aware recurring monitor (if OCF) - If one of those components fails, pacemaker will know to try to recover everything in the group from that point, and if necessary, fence the node and recover the virtual domain elsewhere (if they're in systemd, pacemaker will only know that the virtual domain has failed, and likely keep trying to restart it fruitlessly) - Convenience of things like putting a node in standby mode, and checking resource status on all nodes with one command If you do move them to systemd, be sure to use the resource-agents-deps target to ensure they're started before pacemaker and stopped after pacemaker. -- Ken Gaillot <kgail...@redhat.com> _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
