You could make httpd_service_node1, httpd_service_node2 and httpd_service_node3- services... Or just spread keys and "for x in node1 node2 node3; do ssh $x service httpd start|stop"... -hjp -----Original Message----- From: linux-cluster-bounces@xxxxxxxxxx on behalf of Alex Sent: Thu 8/28/2008 13:20 To: linux clustering Subject: Re: one click to start httpd on all nodes - possible?

This is not working for me. let simplify with 2 nodes. I created a service and a resource, as you suggest: [snip from cluster.conf] <service autostart="1" exclusive="0" name="httpd_service"> <script ref="httpd_script"/> </service> <resources> <script file="/etc/rc.d/init.d/httpd" name="httpd_script"/> </resources> [end snip] Now, supposing that httpd_service is running on one node, clusvcadm -d httpd_service will disable service and stop httpd on that node, but clusvcadm -e httpd_service will enable service on the node where is issued command and will not start service also on the second node...so, as i said, is a failover configuration. I want to be able to controll httpd in parallel on all nodes! So, what is missing from my above cluster.conf setup?
