2022-02-10 Thread Jonno
Hello, I am having some trouble getting my 2 node active/passive cluster to do what I want. More specifically, my cluster is removing the VIP from the cluster whenever I attempt a failover with a command such as "crm resource move rsc_cluster_vip node2". When running the command above, I am
