Dear all, For a two nodes cluster configuration, in the previous days with the "heartbeat" tool, I can configure additional communication channels over extra LAN and serial ports interfaces for communication redundancy. Also, I shall configure ping nodes or ping groups for the cluster nodes to compare their "capability" of communication with the outside world to determine which node shall act as the primary node for a active-passive fail-over configuration. How can I program these or the similar with Corosync and pacemaker ?
With corosync for a two nodes cluster, the default simple configuration with multicast over Ethernet interface cannot tell which node has been down when the communication between the two nodes broke down. This could be the LAN interface on one of the nodes (or the LAN cable or port on the LAN switch), or some route settings problem in between. This shall create a split-brain situation and each node shall announce itself as the only available working node and take over the sharing resources at the same time. Anyone can point me to the right direction ?
