While this indeed looks like a bug, preferred way of ensuring token consistency is to relate nova-cloud-controller to memcached.

@ante,

I assume you mean single-nova-consoleauth=false with memcached relation. single-nova-consoleauth=false has another issue as:

I think this is caused by some timing issues in the setup of the cluster; specifically:

    if True in [ra.startswith('ocf:openstack')
                for ra in resources.itervalues()]:
          apt_install('openstack-resource-agents')

does not happen until the hacluster charm parses relation data from the principle, at which point it might be installed and part of a corosync cluster with its peers; the cluster configuration is propagated from the lead unit, which already has things installed, and we end up with an ocf failure of this type.

I'd actually suggest we move any resource agent install to much earlier in the charm lifecycle, thus avoiding an inconsistent on-disk state with the actual cluster source configuration.

Triaging as Low priority - this is not the recommended way of doing things with regards to HA nova-consoleauth - users should be using the memcache integration instead.

After deployment at customer site we have to issue a crm resource cleanup on one of the nova-cloud-controller nodes to get consoleauth working. Not sure if it matters but we are using dns-ha=true in this deployment.

@james-page The standard FCE bundle templates do not related nova-cloud-controller with memcached and don't set single-nova-consoleauth (the default is true). Should we change this?
