Just realized that you are also deploying 2x compute nodes. Just FYI, even the basic HA setup barely fits on a 32G host. In fact on 3 of the 4 nodes in CI, we rarely get a pass of HA because the resources are so tight. Will actually be switching that job to a single controller job with pacemaker for exactly that reason (email to RDO list about that will come later this afternoon). How big is the virthost you are using? 32 GB . I am currently at VIRTHOST Console and made TOP's snapshot of running config 3xController(HA) + 1xCompute. Snapshot is attached ( Disregard previous message, it was sent occasionally ) Config :- 3xController(HA) + 2xCompute. I was monitoring via TOP many times . I didn't see big problems with RAM Current problem is most probably related with introspection nodes supposed to built overcloud. > > Thank you very much for feedback > Boris. > > <a id="LPlnk357023" href="https://github.com/openstack/tripleo-quickstart/blob/master/config/general_config/ha.yml#L13"> https://github.com/openstack/tripleo-quickstart/blob/master/config/general_config/ha.yml#L13</a> > > It is not 100% that is the root cause of your issue, as the logs below > look like we hit issues either with Ironic deployment to the nodes, or > some issue with Nova scheduler.
