Hi, I recommend you add a stonith device to your cluster configuration. In my case an external/ssh stonith device was sufficient for testing. Later, you have to switch to a more solid stonith solution in your production environment. What you are trying to do is a active/passive cluster which is covered really good in the tutorials on http://www.clusterlabs.org/wiki/Documentation (see 'Clusters from scratch'). I found out that even though in a test environment having a stonith device is essential to judge the behavior of the cluster.

I have set up a 2 node cluster and configured one resource (apache) to migrate from one node to the other. Everything I do is virtually, using Oracle Virtual Boxes. When I "disconnect" the cable of node1 both nodes will be active, running apache and of course they see the other node as offline. But, when I connect the cable again, the resource will stop running on node2, and always it will run on node1. This is not what I want, because in my case node1 is the bad one(he lost the connection). I think I need to set up scores in order to start the resource on the second node when the first one fails. I want that can happen automatically. so, what should I do in this case? when I enter the command *crm configre* and then *ptest scores* I get the following output: group_color: WebServices allocation score on ha2-virtualbox: 0 group_color: WebServices allocation score on ha1-virtualbox: 0 group_color: ip1 allocation score on ha2-virtualbox: 0 group_color: ip1 allocation score on ha1-virtualbox: 100 group_color: ip1arp allocation score on ha2-virtualbox: 0 group_color: ip1arp allocation score on ha1-virtualbox: 100 group_color: apache2 allocation score on ha2-virtualbox: 0 group_color: apache2 allocation score on ha1-virtualbox: 100 native_color: ip1 allocation score on ha2-virtualbox: 0 native_color: ip1 allocation score on ha1-virtualbox: 400 native_color: ip1arp allocation score on ha2-virtualbox: -1000000 native_color: ip1arp allocation score on ha1-virtualbox: 200 native_color: apache2 allocation score on ha2-virtualbox: -1000000 native_color: apache2 allocation score on ha1-virtualbox: 100 my cluster configuration has the followwing output after *crm configure edit * command: node $id="6205c6b0-e45e-4899-ada9-743d5e38938a" ha1-virtualbox node $id="cd44396f-aba9-453b-a75d-5cdc1e63130e" ha2-virtualbox primitive apache2 lsb:apache2 \ op monitor interval="5s" primitive ip1 ocf:heartbeat:IPaddr2 \ params ip="55.55.55.55" nic="eth0:0" primitive ip1arp ocf:heartbeat:SendArp \ params ip="55.55.55.55" nic="eth0:0" group WebServices ip1 ip1arp apache2 colocation apache_with_ip inf: apache2 ip1 property $id="cib-bootstrap-options" \ dc-version="1.0.9-unknown" \ cluster-infrastructure="Heartbeat" \ stonith-enabled="false" rsc_defaults $id="rsc-options" \ resource-stickiness="100" regards, Florin Onciu *********************************************** Florin Onciu, Munkemøllestræde 11 5000 Odense C - Denmark telefon: +45 22 83 56 36 e-mail: [email protected] *********************************************** out of nothing, God can do wonderful things! _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
