When I'm trying to delete a security group, the delete operation fails
neutron security-group-delete f54609e7-f3a3-4b44-8060-2675058ea786
Security Group f54609e7-f3a3-4b44-8060-2675058ea786 in use.
I tried to delete all security group rules and the same error message appears.
How can I release it?
The security group in matter was attached to a nova server. This server also had attached to it a cinder volume. This volume remained stuck in "Creating" status.
Because of this volume, the security group could not be deleted.
I've identified the problem by using
heat event-list <NAME or ID>
