This bug did not make the OSP 8.0 release. It is being deferred to OSP 10. Will reopen if this happens again. Haven't seen it in a while. |
Description of problem: Once in a while, scheduling will fail to select a node when deploying overcloud but retries to schedule the same node and will succeed. | fault | {"message": "No valid host was found.
