Hi On my 2 node clusters I have a UPS connected to them. This UPS is programmed to shutdown both nodes of the clusters. Node 2 shutsdown several minutes before node 1. The fence mechanisms I have setup are primarily an APC network power switch and for backup Dell DRAC with fence_ipmilan. If you shutdown a node where the cluster services are chkconfig'd on, and it withdraws cleanly from the cluster on shutdown it sits at system halted and doesn't power off. If no cluster services have ever been started (all chkconfig'd off) and the system is shutdown, it halts and powers off. Now I know the recommendation is for acpi to be turned off but it makes no difference either way, and I have verified both fence mechanisms power hard down the system acpid or not. By not powering down, the UPS continues to have power drawn from it until it's power off timer expires (that the last node send it in halt.local). This has the effect of needlessly reducing battery capacity and lowering protection from multiple consecutive power outages. What causes the system not to power down, I realise this maybe by design, but is it configurable?
