Comment 2 Zane Bitter 2016-08-16 16:27:56 UTC

Heat just calls delete in Nova and waits until the server cannot be found any more from the Nova API. So unless something is showing up in 'nova list', this is not a bug in Heat. It's likely a bug in either Ironic or Nova.

Comment 3 Joe Talerico 2016-08-16 18:04:35 UTC

Nothing in `nova list`

Comment 4 Joe Talerico 2016-08-16 18:05:19 UTC

Also will note that manually running `ironic node-update uuid remove instance_uuid` cleaned things up.

Comment 5 Lucas Alvares Gomes 2016-09-06 15:45:54 UTC

Hi, 

Thanks for the report Joe, this is a bug in the nova ironic driver it's currently being tracked at https://bugzilla.redhat.com/show_bug.cgi?id=1372392 and there's a backport patch attached to that BZ as well.
