First of all, you need to download the resource agent to your system:
cd /usr/lib/ocf/resource.d/openstack wget https://raw.github.com/madkiss/openstack-resource-agents/master/ocf/neutron-agent-dhcp chmod a+rx neutron-dhcp-agent
You may now proceed with adding the Pacemaker configuration for
Neutron DHCP Agent resource. Connect to the Pacemaker cluster with crm
configure, and add the following cluster resources:
primitive p_neutron-dhcp-agent ocf:openstack:neutron-dhcp-agent \
params config="/etc/neutron/neutron.conf" \
plugin_config="/etc/neutron/dhcp_agent.ini" \
op monitor interval="30s" timeout="30s"This configuration creates
p_neutron-dhcp-agent, a resource for manage Neutron DHCP Agent service
crm configure supports batch input, so you may copy and paste the
above into your live pacemaker configuration, and then make changes as
required.
Once completed, commit your configuration changes by entering commit
from the crm configure menu. Pacemaker will then start the Neutron DHCP
Agent service, and its dependent resources, on one of your nodes.
