Fencing is not juste about IPMI: * you can use external smart devices to shut down your nodes (eg. PDU, UPS, a self-made fencing device (https://www.alteeve.com/w/Building_a_Node_Assassin_v1.1.4)) * you can fence a node by disabling its access to the network from a manageable switch, without shutting down the node * you can use 1/2/3 shared storage + the hardware RPi watchdog using the SBD service * you can use the internal hardware RPi watchdog using the SBD service, without shared disk Regards, _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
