I want to set up a cluster with 5 nodes, however only three have two nics, the other nodes have only one.

When I add an interface and the corresponding ring addresses to the three nodes in corosync.conf, the daemon throws the error Configuration is not valid: parse error in config: Not all nodes have the same number of links

So my question is: is a cluster with "unequal" nodes even possible and how should the corosync.conf look like?
