We've been having some issues with heat delete-stack in Juno. The issues generally fall into three categories:
1) it takes multiple calls to heat to delete a stack. Presumably due to heat being unable to figure out the ordering on deletion and resources being in use. 2) undeleteable stacks. Stacks that refuse to delete, get stuck in DELETE_FAILED state. In this case, they show up in stack-list and stack-show, yet resource-list and stack-delete deny their existence. This means I can't be sure whether they have any real resources very easily. 3) As a corollary to item 1, stacks for which heat can never unwind the dependencies and stay in DELETE_IN_PROGRESS forever. Does anyone have any work-arounds for these or recommendations on cleanup? My main worry is removing a stack from the database that is still consuming the customer's resources.
