Hi, a question probably easy but I'm stuck on it by now. I have Pacemaker installed from the RHEL62 repository, and I have some resources that should be operating just if an external ping gateway answers the ping request.
I performed a simplified configuration in order to test the following behavior: if the ping gateway is not reached the other resource should shut down (and swap on the other node). I also avoided to clone the resource in the test configuration. There are a couple of things I'm not able to understand. 1. MISSING PING GATEWAY NOT DETECTED. if I detach the network interface leading to the gateway, I'd expect Pacemaker to get that. It doesn't happen; furthermore, in the message log I get what follows: Oct 16 11:29:34 SDGRMA lrmd: [29124]: info: perform_op:2884: operation monitor[49] on ocf::ping::resource_ping_gateway for client 29127, its parameters: CRM_meta_interval=[5000] host_list=[172.16.8.20] name=[ping_gateway] dampen=[5s] crm_feature_set=[3.0.5] CRM_meta_enabled=[true] CRM_meta_on_fail=[restart] CRM_meta_name=[monitor] multiplier=[1000] CRM_meta_timeout=[20000] CRM_meta_requires=[nothing] for rsc is already running. Oct 16 11:29:34 SDGRMA lrmd: [29124]: info: perform_op:2894: postponing all ops on resource resource_ping_gateway by 1000 ms 2. DIFFICULTY SETTING THE "DON'T RUN ON UNCONNECTED NODES" OPTION (example 9.3 in Pacemaker online docs). If I try to set this constraint, even if the ping gateway is available the virtual ip stops (until the constraint is removed). What's wrong? crm configure log-active ping rule -inf: not_defined resource_ping_gateway or resource_ping_gateway lte 0 (pls see cib down here) I've read somewhere it is possible to use something like that to check the pingd status "crm_attribute -G -t status -N -n pingd" But I can't find any "pingd" attribute in my cib. ------- Any suggestion will be really appreciated. Thanks a lot G. ------- TEST CIB I set 2 resources: a ping gateway (still to clone) and a virtual IP. <cib epoch="82" num_updates="0" admin_epoch="0" validate-with="pacemaker-1.2" crm_feature_set="3.0.5" update-origin="SDGRMA" update-client="cibadmin" cib-last-written="Mon Oct 15 18:47:45 2012" have-quorum="1" dc-uuid="SDGRMA"> <configuration> <crm_config> <cluster_property_set id="cib-bootstrap-options"> <nvpair id="cib-bootstrap-options-dc-version" name="dc-version" value="1.1.6-3.el6-a02c0f19a00c1eb2527ad38f146ebc0834814558"/> <nvpair id="cib-bootstrap-options-cluster-infrastructure" name="cluster-infrastructure" value="openais"/> <nvpair id="cib-bootstrap-options-expected-quorum-votes" name="expected-quorum-votes" value="2"/> <nvpair id="cib-bootstrap-options-no-quorum-policy" name="no-quorum-policy" value="ignore"/> <nvpair id="cib-bootstrap-options-symmetric-cluster" name="symmetric-cluster" value="false"/> <nvpair id="cib-bootstrap-options-stonith-enabled" name="stonith-enabled" value="false"/> <nvpair id="cib-bootstrap-options-start-failure-is-fatal" name="start-failure-is-fatal" value="false"/> </cluster_property_set> </crm_config> <nodes> <node id="SDGRMA" type="normal" uname="SDGRMA"/> <node id="SDGRMB" type="normal" uname="SDGRMB"/> </nodes> <resources> <primitive class="ocf" id="resource_ping_gateway" provider="pacemaker" type="ping"> <instance_attributes id="resource_ping_gateway-instance_attributes"> <nvpair id="resource_ping_gateway-instance_attributes-host_list" name="host_list" value="172.16.8.20"/> <nvpair id="resource_ping_gateway-instance_attributes-dampen" name="dampen" value="5s"/> <nvpair id="resource_ping_gateway-instance_attributes-multiplier" name="multiplier" value="1000"/> <nvpair id="resource_ping_gateway-instance_attributes-name" name="name" value="ping_gateway"/> </instance_attributes> <operations> <op enabled="true" id="resource_ping_gateway-startup" interval="5s" name="monitor" on-fail="restart" requires="nothing" timeout="20s"/> <op id="resource_ping_gateway-start-0" interval="0" name="start" timeout="180s"/> <op id="resource_ping_gateway-stop-0" interval="0" name="stop" timeout="180s"/> </operations> <meta_attributes id="resource_ping_gateway-meta_attributes"> <nvpair id="resource_ping_gateway-meta_attributes-target-role" name="target-role" value="Started"/> </meta_attributes> </primitive> <primitive class="ocf" id="resource_vrt_ip" provider="heartbeat" type="IPaddr2"> <instance_attributes id="resource_vrt_ip-instance_attributes"> <nvpair id="resource_vrt_ip-instance_attributes-ip" name="ip" value="192.168.15.73"/> <nvpair id="resource_vrt_ip-instance_attributes-nic" name="nic" value="bond0"/> </instance_attributes> <meta_attributes id="resource_vrt_ip-meta_attributes"> <nvpair id="resource_vrt_ip-meta_attributes-target-role" name="target-role" value="Started"/> <nvpair id="resource_vrt_ip-meta_attributes-multiple-active" name="multiple-active" value="stop_start"/> <nvpair id="resource_vrt_ip-meta_attributes-migration-threshold" name="migration-threshold" value="3"/> <nvpair id="resource_vrt_ip-meta_attributes-failure-timeout" name="failure-timeout" value="0"/> </meta_attributes> <operations> <op enabled="true" id="resource_vrt_ip-startup" interval="60" name="monitor" on-fail="restart" requires="nothing" timeout="180s"/> <op id="resource_vrt_ip-start-0" interval="0" name="start" timeout="180s"/> <op id="resource_vrt_ip-stop-0" interval="0" name="stop" timeout="180s"/> </operations> </primitive> </resources> <constraints> <rsc_location id="loc-1a" node="SDGRMA" rsc="resource_ping_gateway" score="200"/> <rsc_location id="loc-1b" node="SDGRMB" rsc="resource_ping_gateway" score="0"/> <rsc_location id="loc-2a" node="SDGRMA" rsc="resource_vrt_ip" score="200"/> <rsc_location id="loc-2b" node="SDGRMB" rsc="resource_vrt_ip" score="0"/> </constraints> </configuration> </cib> _______________________________________________ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
