A node in CLEAN FAILED must be moved to MANAGEABLE state before it can be told to "provide" (which eventually puts it back in AVAILABLE).

Try this:
`openstack baremetal node manage UUID`, then run the command with "provide" as you did before.

The available states and their transitions are documented here: https://docs.openstack.org/ironic/latest/contributor/states.html

I'll note that if cleaning failed, it's possible the node is misconfigured in such a way that will cause all deployments and cleanings to fail (e.g.; if you're using Ironic with Nova, and you attempt to provision a machine and it errors during deploy; Nova will by default attempt to clean that node, which may be why you see it end up in clean failed). So I strongly suggest you look at the last_error field on the node and attempt to determine why the failure happened before retrying.

Good luck!

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 |

+--------------------------------------+------------+---------------+-------------+--------------------+-------------+

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
