[ClusterLabs] ping Resource Agent doesnt work
I configured ping-RA via ocf:pacemaker. During testing the resource-agent works fine, it executes ping action to my gateway every 10 seconds and 3 attempts. But I noticed that even I disconnect the physical link of node where the resource resides, it doesnt failover to other node. *IP CONFIG:* 172.16.10.0/24 = interface to gateway 172.16.11.0/24= heartbeat link (interface to avoid split brain as my goal is to only failover ping-resource after 3-attempts failure to ping my gateway) *CONFIG:* [root@node1 ~]# pcs config Cluster Name: clusterPa Corosync Nodes: node1 node2 Pacemaker Nodes: node1 node2 Resources: Resource: ping-gateway (class=ocf provider=pacemaker type=ping) Attributes: host_list=172.16.10.1 Operations: monitor interval=10 timeout=60 (ping-gateway-monitor-interval-10) start interval=0s timeout=60 (ping-gateway-start-interval-0s) stop interval=0s timeout=20 (ping-gateway-stop-interval-0s) Stonith Devices: Fencing Levels: Location Constraints: 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: clusterPa dc-version: 1.1.16-12.el7-94ff4df have-watchdog: false last-lrm-refresh: 1531899781 stonith-enabled: false Quorum: Options: [root@node1 ~]# ___ Users mailing list: Users@clusterlabs.org https://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
