Description Andreas Karis 2019-05-31 17:08:01 UTC

Description of problem:
Undercloud: /var/lib/neutron/dhcp/<UUID>/leases contains old / stale entries that lead to a failure when ironic runs its automatic node cleanup --- when the node PXE boots, it never gets a DHCP lease from neutron's dnsmasq. This happens when running `heat stack-delete <stack name>`.

A restart of all neutron* services fixes this issue and cleanup works.
~~~
sudo systemctl restart neutron*
~~~

Then, this works:
~~~
openstack baremetal node abort <node>
openstack baremetal node manage <node>
openstack baremetal node provide <node>
~~~
