I'm running 1.0.8. In accordance with the bug in the post you linked, I changed the config so that interval is greater than dampen. Here is the relevant section now:
<clone id="connectivity_resource"> <primitive class="ocf" id="ping" provider="pacemaker" type="ping"> <instance_attributes id="ping-attrs"> <nvpair id="pingd-dampen" name="dampen" value="5s"/> <nvpair id="pingd-multiplier" name="multiplier" value="100"/> <nvpair id="pingd-hosts" name="host_list" value="10.54.130.6 10.54.130.8 10.54.130.7 50.97.196.101 50.97.196.103 50.97.196.102"/> </instance_attributes> <operations> <op id="ping-monitor-10s" interval="10s" name="monitor" timeout="60s"/> </operations> </primitive> <meta_attributes id="connectivity_resource-meta_attributes"> <nvpair id="connectivity_resource-meta_attributes-target-role" name="target-role" value="Started"/> </meta_attributes> </clone> The scores are still not what I expect however, and when I disable the internal interface on a node, nothing happens with failover. Also, I've noticed this in my syslog: Feb 17 06:26:11 anlutest2 lrmd: [1137]: WARN: ping:1:monitor process (PID 9380) timed out (try 1). Killing with signal SIGTERM (15). Feb 17 06:26:11 anlutest2 lrmd: [1137]: info: RA output: (ping:1:monitor:stderr) Terminated Feb 17 06:26:11 anlutest2 ping[9380]: [15745]: INFO: They use TERM to bring us down. No such luck. Feb 17 06:26:11 anlutest2 ping[9380]: [15747]: ERROR: Unexpected result for 'ping -n -q -W 3 -c 5 50.97.196.103' 143: So it looks like the ping command is failing for some reason, but when I run it manually, it succeeds... Really at a loss here, any help is appreciated!
