"power_wait" parameter for fence_ipmilan seems not be supported yet in el5.5 based distro; to achieve the same as with "-t 10", please use "timeout" parameter instead - not sure if this will explain what you observe or not 2. as of el5.5, conga is still using direct /sbin/fence_node invocation (direct library call is used since some later version), so you can mimic (and possibly debug, e.g., with strace) what luci triggers with "fence this node" by running on the respective node: /sbin/fence_node -O NODENAME where NODENAME is the respective clusternode's "name" parameter in cluster.conf Hope this helps. -- Jan -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
