I've been doing a lot of instance creation/deletion/evacuate and I've noticed that if I

1)create an instance
2) power off the compute node it was running on
3) delete the instance
4) boot up the compute node

then the instance rootfs stays around in /var/lib/nova/instances/. Eventually this could add up to significant amounts of space.


Is this expected behaviour? (This is on grizzly, so maybe havana is different.) If not, should I file a bug for it?

I think it would make sense for the compute node to come up, query all the instances in /var/lib/nova/instances/, and delete the ones for instances that aren't in the database.
