When I have seen this, it was because the stack didn't fully reset all
the nodes to available (assuming the stack was fully deleted). Can you
run "ironic node-list" at the undercloud command-line, and make sure
that all your nodes are set to "available"? If not, you can manually set
the provisioning mode with "ironic node-set-provision-state <UUID>
provide" for each node. Also, make sure that the stack has been fully
deleted ("heat stack-list"), although I don't think that is the issue here.
