Description of problem: With the merging of the pcs on host patchset for 16.2 we are seeing a problem with FFUs on Instance HA environments. Preamble: tripleo keeps the stonith-enabled cluster property set to false until step 5. With the pcs on host patchset the enablement happens still at step 5 but it gets triggered during tripleo_ha_wrapper deployment task of cinder-volume which tries to restart the cinder-volume service (during the leapp of the first controller) and this hangs forever because pacemaker is in the following transition: - stonith-fence_compute-fence-nova is configured - pacemaker wants to call stonith on for controller-0 (which is probably dumb, but it is unlikely we'll be able to change that in the right timeframe as it seems a potentially involved change in behaviour) - Any other action, like cinder-volume restart in this case, is stuck and the FFU fails.
