[ClusterLabs] 2 Nodes Pacemaker for Nginx can only failover 1 time
Hello Everyone, I setup a cluster with two nodes with pacemaker 1.1.10 on CentOS 7. Then I downloaded aresource agent for nginx from github https://github.com/ClusterLabs/resource-agents/blob/master/heartbeat/nginx I tested my setup like this: 1. Node 1 is started with the nginx and vip, everyting is ok 2. Kill Node1 nginx, wait for a few seconds 3. See the ngnix and vip are moved to node2, failover succeeded, and Node1 doesn't have any resources active 4. I kill nginx on node2, but nginx and vip don't come back to Node1 I set no-quorum-policy=ignore and stonith-enabled=false. Why won't pacemaker let the resource come back to Node1? What did I miss here? I guess the node1 is still in some failure status, how can I recovery the node? Does anyone can shed some light on my questions? Thank you in advance.

Hello Jacob, Look at the journal. It will tell you. Also, it's hard to debug without any information from the daemons. Regards, Noel Kuntze Am 9.

I kill nginx on node2, but nginx and vip don't come back to Node1 I set |no-quorum-policy=ignore| and |stonith-enabled=false|. Without fencing (stonith), the cluster will enter an undefined state after a node fails and debugging becomes very difficult. Please configure (and test!) stonith, then see if your problem remains.
