I just want to move resources when connection on one ring is lost.
If you have two working rings, and one is lost, then the other will be
used automatically, with no resource failover required. "Nothing
happened" in that case is the desired outcome.
If you lose your only ring (or all rings), then fencing is required for
the cluster to recover resources safely.
As an example, let's say we have two nodes, and two networks, one used
for public-facing services and one used for cluster communication, with
an IP address as the highly available resource. If the cluster
communication link fails but the public-facing link is still up, without
fencing both nodes could bring up the IP address. That would lead to
some packets going to one node and some to the other, rendering the
service completely unusable. Fencing allows one node to be sure the
other is not using the IP. Once you use shared storage, databases, and
such, the risk is much greater -- a reconciliation nightmare at best,
complete data loss at worst.

Resources shuld move to second node when any interface is down.
