Hi,
May someone mention this before but I don't know. Just some thoughts.
In release 1, we only support 2 nodes, so the heartbeat connections are
symmetric.
But in release 2, we can support more than 2 nodes, then in many real
cases, the connections may not be symmetric.
For example, a three nodes cluster, and there is only one serial cable
between two nodes of all three nodes.
Maybe we can let every nodes have their own heartbeat connections
configuration(maybe separated from from ha.cf, or have different ha.cf
in cluster).
And heartbeat or some other component will keep a connection map or
topologic map of cluster.
This may help user to use even one cable to increase the redundance.
You can already have different ha.cf files in the cluster.
It is not normally recommended - because it eventually tends to cause
mistakes with them being different.
