Scale down is broken also in RHOS 9 (See attachment)
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
