I have three machines named anlutest1, anlutest2, and anlutest3 that I'm trying to get IP failover working on. I'm using heartbeat for the messaging layer, and everything works great when a machine goes down. But I also would like to failover an IP when EITHER the eth0 or eth1 network interfaces fail. From reading
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/ch09s03s03.html it seems the right way to do this is to add a ping resource. Here is my XML configuration: http://pastebin.com/05z7eB2s This config doesn't work for me. Using the showscores.sh script found at: http://www.mail-archive.com/pacemaker@oss.clusterlabs.org/msg00410.html I see that my scores are: Resource Score Node Stickiness #Fail Migration-Threshold address01 0 anlutest3 0 0 address01 1006 anlutest1 0 5 address01 50 anlutest2 0 157 address02 0 anlutest3 0 0 address02 1050 anlutest2 0 2 address02 6 anlutest1 0 0 address03 1000 anlutest3 0 7 address03 50 anlutest2 0 address03 6 anlutest1 0 0 ping:0 0 anlutest1 0 6 ping:0 0 anlutest2 0 14 ping:0 0 anlutest3 0 0 ping:1 0 anlutest2 0 ping:1 0 anlutest3 0 28 ping:1 -1000000 anlutest1 0 0 ping:2 0 anlutest3 0 13 ping:2 -1000000 anlutest1 0 0 ping:2 -1000000 anlutest2 0 which make no sense at all. I don't see how I could be getting these scores of 50 and 1006. When I take down an interface on anlutest3, I see scores of 4 and 1004, which sort of make sense, just the multiplier of 100 isn't working. I was experimenting with changing values, so maybe its caching old values. If so, how do I enforce the new values? Furthermore, shouldn't there be no scores of 0? If all 6 IPs I am pinging return successfully, shouldn't my scores be either 600 or 1600? In my syslog I also see a ton of messages like Feb 17 03:54:47 anlutest2 lrmd: [1137]: info: perform_op:2877: operations on resource address01 already delayed Feb 17 03:54:48 anlutest2 lrmd: [1137]: info: perform_op:2873: operation monitor[419] on ocf::ping::ping:1 for client 1140, its parameters: CRM_meta_clone=[1] host_list=[10.54.130.6 10.54.130.8 10.54.130.7 50.97.196.101 50.97.196.103 50.9CRM_meta_clone_max=[3] dampen=[60s] crm_feature_set=[3.0.1] CRM_meta_globally_unique=[false] multiplier=[10000] CRM_meta_name=[monitor] CRM_meta_timeout=[60000] CRM_meta_interval=[5000] for rsc is already running.

Or if there's a better way to do what I want to do... Thanks in advance, Anlu
