Hi, Currently trying to scale out using a TripleO-quickstart setup. I have created an environment with 3 control nodes and 9 computer nodes using a config.yaml. As extra_args in this configuration I purposely only did --control-scale 3 (with pacemaker). The deploy of --tags all finishes completely. And as expected, only 1 (out of 9) compute node is up. As a result I have an environment that is working as * undercloud * control-[0-2] * compute-7 After this, I login to the undercloud machine. Check the status with ironic node-list and see all nodes in Provisiong State = available, all remaining compute nodes show Power State = None and the other nodes are seen as power off (control-[0-2] and compute-7). Now when retrying to deploy with e.g. `--compute-scale 2` the overcloud can not find request nodes to deploy to. The stack fails with "Deployment failed: Not enough nodes - available: 0, requested: 2". E.g. `ironic node-show compute-8` indicates that it is available and properties/capabilities includes profile:compute. What needs to be done to scale out using these settings to include the remaining 8 compute nodes? regards, Gerard -- Gerard Braad — 吉拉德 F/OSS & IT Consultant in Beijing http://gbraad.nl gpg: 0x592CFE75
