Hi, On my two-node active/passive setup, I configured fencing via fence_vmware_soap. I configured pcmk_delay=0 on both nodes so I expected that both nodes will be stonithed simultaenously.
On my test scenario, Node1 has ClusterIP resource. When I disconnect service/corosync link physically, Node1 was fenced and Node2 keeps alive given pcmk_delay=0 on both nodes. Can you explain the behavior above? See my config below: [root@ArcosRhel2 cluster]# pcs config Cluster Name: ARCOSCLUSTER Corosync Nodes: ArcosRhel1 ArcosRhel2 Pacemaker Nodes: ArcosRhel1 ArcosRhel2 Resources: Resource: ClusterIP (class=ocf provider=heartbeat type=IPaddr2) Attributes: cidr_netmask=32 ip=172.16.10.243 Operations: monitor interval=30s (ClusterIP-monitor-interval-30s) start interval=0s timeout=20s (ClusterIP-start-interval-0s) stop interval=0s timeout=20s (ClusterIP-stop-interval-0s) Stonith Devices: Resource: Fence1 (class=stonith type=fence_vmware_soap) Attributes: action=off ipaddr=172.16.10.151 login=admin passwd=123pass pcmk_host_list=ArcosRhel1 pcmk_monitor_timeout=60s port=ArcosRhel1(Joniel) ssl_insecure=1 pcmk_delay_max=0s Operations: monitor interval=60s (Fence1-monitor-interval-60s) Resource: fence2 (class=stonith type=fence_vmware_soap) Attributes: action=off ipaddr=172.16.10.152 login=admin passwd=123pass pcmk_delay_max=0s pcmk_host_list=ArcosRhel2 pcmk_monitor_timeout=60s port=ArcosRhel2(Ben) ssl_insecure=1 Operations: monitor interval=60s (fence2-monitor-interval-60s) Fencing Levels: Location Constraints: Resource: Fence1 Enabled on: ArcosRhel2 (score:INFINITY) (id:location-Fence1-ArcosRhel2-INFINITY) Resource: fence2 Enabled on: ArcosRhel1 (score:INFINITY) (id:location-fence2-ArcosRhel1-INFINITY) Ordering Constraints: Colocation Constraints: Ticket Constraints: Alerts: No alerts defined Resources Defaults: No defaults set Operations Defaults: No defaults set Cluster Properties: cluster-infrastructure: corosync cluster-name: ARCOSCLUSTER dc-version: 1.1.16-12.el7-94ff4df have-watchdog: false last-lrm-refresh: 1531810841 stonith-enabled: true Quorum: Options:
