Hello Team, I had a situation where my undercloud-node had a problem with it’s disk and has disconnected from overcloud. I couldn’t restore the undercloud controller and ended up re-installing it (running 'openstack undercloud install’). The installation ended successfully but now I’m in a situation where Cleanup of the overcloud deployed nodes fails: (undercloud) [stack@interop010 ~]$ openstack baremetal node list +--------------------------------------+------------+---------------+-------------+--------------------+-------------+ | UUID | Name | Instance UUID | Power State | Provisioning State | Maintenance | +--------------------------------------+------------+---------------+-------------+--------------------+-------------+ | 97b9a603-f64f-47c1-9fb4-6c68a5b38ff6 | interop025 | None | power on | clean failed | True | | 4b02703a-f765-4ebb-85ed-75e88b4cbea5 | interop026 | None | power on | clean failed | True | +--------------------------------------+------------+---------------+-------------+--------------------+-------------+ I’ve tried to move node to available state but cannot: (undercloud) [stack@interop010 ~]$ openstack baremetal node provide 97b9a603-f64f-47c1-9fb4-6c68a5b38ff6 The requested action "provide" can not be performed on node "97b9a603-f64f-47c1-9fb4-6c68a5b38ff6" while it is in state "clean failed". (HTTP 400) My question is: How do I make the nodes available again? as the deployment of overcloud fails with: ERROR due to "Message: No valid host was found. , Code: 500” Thanks, Igal
