Hi All, I am working on 3 node cluster with corosync+pacemaker on RHEL 6. Eventhough I applied anti-affinity the app is still trying to run on 3rd node.
# rpm -qa|grep corosync corosync-1.4.1-17.el6_5.1.x86_64 corosynclib-1.4.1-17.el6_5.1.x86_64 # rpm -qa | grep -i pacemaker pacemaker-1.1.10-14.el6_5.3.x86_64 pacemaker-libs-1.1.10-14.el6_5.3.x86_64 pacemaker-cluster-libs-1.1.10-14.el6_5.3.x86_64 pacemaker-cli-1.1.10-14.el6_5.3.x86_64 # rpm -qa | grep -i crm crmsh-2.0+git5-1.1.x86_64 # crm configure primitive oc_app lsb::app meta migration-threshold=10 failure-timeout=300s op monitor interval=3s # crm configure clone oc_app_clone oc_app meta clone-max=2 globally-unique=false interleave=true # crm configure location nvp_prefer_node oc_app_clon -inf: "common-test-redhat" Online: [ common-test-redhat test-redhat-1 test-redhat-2 ] Full list of resources: Clone Set: oc_app_clone [oc_app] oc_app (lsb:app): FAILED common-test-redhat (unmanaged) Started: [ test-redhat-1 ] Stopped: [ test-redhat-2 ] The same configuration worked correctly on ubuntu and it started oc_app on only 2 nodes and not on common-test-redhat node. after some time: ------------------------- Clone Set: oc_app_clone [oc_app] Started: [ test-redhat-1 ] Stopped: [ common-test-redhat test-redhat-2 ] # crm configure show node common-test-redhat node test-redhat-1 node est-redhat-2 primitive oc_app lsb:app \ meta migration-threshold=10 failure-timeout=300s \ op monitor interval=3s clone oc_app_clone oc_app \ meta clone-max=2 globally-unique=false interleave=true location nvp_prefer_node oc_app_clone -inf: common-test-redhat property cib-bootstrap-options: \ dc-version=1.1.10-14.el6_5.3-368c726 \ cluster-infrastructure="classic openais (with plugin)" \ expected-quorum-votes=3 \ stonith-enabled=false Can someone please help me on the configuration.
