Hi All I had configured Heartbeeat, pacemkaer on my two VM's
Cluster with two nodes, two nodes are running *cent-os* as operation systems. Cluster configured with 8 resources and defined order, taking reference pacemaker explained please find the order and co-location constraints, taken from cib.xml <rsc_colocation id="Httpd-with-ip" rsc="HttpdVIP" score="INFINITY" with-rsc="Httpd"/> <rsc_colocation id="Tomcat1-with-ip" rsc="Tomcat1VIP" score="INFINITY" with-rsc="Tomcat1"/> <rsc_colocation id="Mysql-with-ip" rsc="MysqlVIP" score="INFINITY" with-rsc="MS_Mysql" with-rsc-role="Master"/> <rsc_order first="HttpdVIP" id="Httpd-after-op" score="INFINITY" then="Httpd"/> <rsc_order first="MysqlVIP" id="Mysql-after-ip" score="INFINITY" then="MS_Mysql"/> <rsc_order first="Tomcat1VIP" id="Tomcat1-after-ip" score="INFINITY" then="Tomcat1"/> <rsc_order first="MS_Mysql" id="Tomcat1-after-MYSQL" score="INFINITY" then="Tomcat1VIP"/> <rsc_colocation id="Tomcat2-with-Tomcat" rsc="Tomcat1" score="INFINITY" with-rsc="Tomcat2VIP"/> <rsc_order first="Tomcat2VIP" id="Tomcat2-after-ip" score="INFINITY" then="Tomcat2"/> <rsc_order first="Tomcat2" id="Httpd-after-Tomcat2" score="INFINITY" then="Httpd"/> <rsc_colocation id="tomcat2-with-ip" rsc="Tomcat2VIP" score="INFINITY" with-rsc="Tomcat2"/> so when heartbeat start on both nodes, the order resources started are MysqlVIP-->MSMysql-->tomcat1VIP-->Tomcat-->Tomcat2VIP-->tomcat2-->HttpdVIP-->Httpd My question is when i try to stop Mysql process since there is an order constraint .all the resources should stop, but still, when i do *crm_mon *i see tomcat2,tomcat2vip,http,httpdVIP resources running on cluster frame work , can you please suggest me if there is any flaw in determining the order or co-location constraints. Regards Rakesh
