[openstack-dev] [heat] heat delete woes in Juno

Hi Matt 

I had similar problems with heat, and the work-around that i used is to abandon the stack (heat stack-abandon), 
and then I delete stack resources created one by one. 

Hope this helps.

Nobody on the operators list had any ideas on this, so re-posting here. 

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. I also don't just want to remove stacks from the database and leave orphaned records in the DB.
