Hi! I'm working with both Ironic and Blazar, and came across a strange interaction that I was wondering if the Blazar devs were aware of. I had four Ironic nodes registered, and only node A had an instance running on it. I tried adding node B - which was available - to the freepool and got this error: 2019-02-13 09:42:28.560 220255 ERROR oslo_messaging.rpc.server ERROR: Servers [[{u'uuid': u'298e83a4-7d5e-4aae-b89a-9dc74b4278af', u'name': u'instance-00000011'}]] found for host a00696d5-32ba-475e-9528-59bf11cffea6 This was strange, because the instance in question was running on node A, and not node B. After some investigation, the cause was identified as the following: https://bugs.launchpad.net/nova/+bug/1815793 But in the meantime, my question is: have other people using Blazar and Ironic run into this issue? It would seem to imply that Ironic nodes can only be added to the freepool if no instances are created, which poses a long-term maintenance issue. Is there a workaround? Thanks, Tzu-Mainn Chen
