Hello All, I installed openstack newton p with a pacemaker cluster made up of 3 controllers and 2 compute nodes. All computer have centos 7.3. Compute nodes are provided with remote pacemaker ocf resource. If before shutting down a compute node I disable the compute node resource in the cluster and enable it when the compute returns up, it work fine and cluster shows it online. If the compute node goes down before disabling the compute node resource in the cluster, it remains offline also after it is powered up. The only solution I found is removing the compute node resource in the cluster and add it again with a different name (adding this new name in all controllers /etc/hosts file). With the above workaround it returns online for the cluster and all its resources (openstack-nova-compute etc etc....) return to work fine. Please, does anyone know a better solution ? Regards Ignazio
