The openstack_admin::controller::ha class provides high-availability to an OpenStack controller via corosync and drbd.

See examples/site.pp for an example of how to use the class.

Usage notes

  • Both the active and passive controller must be provisioned simultaneously to allow DRBD to synchronize.
  • Memcached does not run correctly under corosync; it is configured to always run on both the active and passive controller.
