Cause: Deployment roles were not loaded correctly by refresh on OSP12.

Consequence: Scale down action which depends on these roles was not usable (cannot proceed in UI).

Fix: Refresh parsing of Heat Stacks for OSP12 was fixed.

Result: Deployment roles are available and nothing prevents pass the UI form for Scale down action and perform it.

Description of problem:
Scaling down infra provider compute nodes is not available after toggling a compute node maintenance mode

Version-Release number of selected component (if applicable): over RHOS 12

How reproducible:

Steps to Reproduce:
1. Enable maintenance mode on a compute node
2. Navigate to Compute > Infrastructure > providers
3. Enter infra provider details
4. Go to Configuration > Scale this Infrastructure Provider Down

Hi Jad, I can see a Vm running on each of Hosts. That most propably prevents from scale down.

Steps to do it could be 1. put node to maintenance mode (so nova will not assign new VM to the Host), 2. migrate instances to another node, 3. node should be available to remove/scale down. Could you try it?

Correction: It is working on RHOS 9.  looks like misconfiguration issue
