i can try.
We have a HA-Cluster with two F5 Loadbalancer (LB1 and LB2), on this cluster is an pool with two nodes (primary and secondary), primary node hast configured manual resume, secondary not.
This all works as intended.
Problem is if LB1 is the active member of the cluster and lost network connection to primary node and LB2 doesent, it routes the traffic to secondary node. If now LB1 goes down (in example lost power) and LB2 is now the active clustermember, it routes traffic again to the primary node because it doesnt know that LB1 switched to the secondary node.
