How to configure manual resume for the second failover only (rollback)

breizho35, do you not need to just enable "manual resume" on the node1 monitor (i assume you have two monitors, a different one per node)?

This way if node1 fails, node 2 takes the traffic. if node1 comes back up then it needs manual intervention?

You could probably improve this with Priority Group Activation (if you haven't already). If node1 has a higher priority then once you manually resume that pool member all traffic should then be served by it, independent on node2 availability. See Priority-based member activation

Hope this helps. If not then an anonymised config of you pool setup may help.
