Thank you for the reply, I try severing the heartbeat nic and add set the `no-quorum-policy` to `ignore` (I forgot that one) like this:
# crm configure property no-quorum-policy=ignore and it works nicely. Thank you, Ariel On 10/29/2014 03:27 PM, Sven Moeller wrote:
You can try to force a split brain by shutting down the heartbeat NICs and keep corosync running on both nodes. Regards Sven Ariel S <ariel_bis2...@yahoo.co.id> schrieb:Hello, I'm trying to understand how this STONITH works. I have 2 VMware VMs (moon1a, moon1b) on two different hosts. Each have 2 nic assigned: eth0 for heartbeat while eth1 used for everything else. This is my testing configuration: node $id="168428034" moon1a node $id="168428035" moon1b primitive Foo ocf:heartbeat:Dummy primitive stonith_moon1a stonith:fence_vmware_soap \ params ipaddr="192.168.1.134" login="foo" \ uuid="42053b22-d3fd-25fe-6fb3-7cb2c7cd2c63" \ action="off" verbose="true" passwd="bar" \ ssl="true" \ op monitor interval="60s" primitive stonith_moon1b stonith:fence_vmware_soap \ params ipaddr="192.168.1.134" login="foo" \ uuid="4205b986-4426-5de4-1069-b10a77123bc4" \ action="off" verbose="true" passwd="bar" \ ssl="true" \ op monitor interval="60s" clone FooClones Foo location loc_stonith_moon1a stonith_moon1a -inf: moon1a location loc_stonith_moon1b stonith_moon1b -inf: moon1b property $id="cib-bootstrap-options" \ dc-version="1.1.10-42f2063" \ cluster-infrastructure="corosync" \ stonith-enabled="true" \ last-lrm-refresh="1414565715" rsc_defaults $id="rsc-options" \ resource-stickiness="200" The vCenter is at 192.168.1.134 and the uuids taken from a list generated by fence_vmware_soap. When I do fencing manually using: # fence_vmware_soap -z -a 192.168.1.134 \ -l foo -p bar \ -U 4205b986-4426-5de4-1069-b10a77123bc4 \ -o off>from moon1a, as expected the moon1b(4205b986-4426-5de4-1069-b10a77123bc4) VM died, so the configuration should be right, I think. But so far I cant emulate split brain by killing corosync like this: # killall -9 corosync My questions: 1. Is my configuration correct? 2. How one cause a split-brain to trigger the expected stonith behavior?
