+ | ===== A note about Multicast Traffic ===== | ||
+ | * corosync and Proxmox clustering need multicast traffic to be configured properly for cluster nodes to see each other. | ||
+ | * If a node keeps losing contact with other members make sure IGMP snooping is turned off at the switch and layer 2 level. | ||
+ | * If some nodes connect initially then disconnect after a few minutes take a look at the multicast configuration of the switches these nodes connect through. | ||
