Hi all, we found a bug with nova-compute nodes in creating since release v1.2.1 You will run into that issue when updating yaook to 1.2.1 or any newer version, if you have computenodes in state creating while updating the nova-compute-operator. We will try to build a fix, but maybe we just keep it as is. A workaround can be found in the issue[1] and after the upgrade and fixing once, the issue don't occur again. Also it is hopefully for the most environments possible to do the update when all nodes are finished with creation. If you want a fix, of cause, you can comment at the issue[1] or reply here.
