(Get the code!)
Cores, instances and ram get out of sync, for cinder it's volumes, gigabytes and snapshots.
It can happen when you delete an instance but it fails to delete, it will go to vm_state error, task_state deleting.
This will decrement the quota_usage values.
This instance still remains in the system for the user and they are able to delete it again. This causes quota_usage values to be decremented again.
This is pretty critical for us as it means projects can use more than their quota.
This is an easy one to replicate but the most common out of sync errors we get are when quota_usage values are higher than they should be.
I'll try and get some more concrete examples.
