Title:
ResourceTracker doesn't clean up compute_nodes or stats entries
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) queens series:
Confirmed
Bug description:
This was noted in review:
https://review.openstack.org/#/c/587636/4/nova/compute/resource_tracker.py@141
That the ResourceTracker.compute_nodes and ResourceTracker.stats (and
old_resources) entries only grow and are never cleaned up as we
rebalance nodes or nodes are deleted, which means it just takes up
memory over time.
When we cleanup compute nodes here:
https://github.com/openstack/nova/blob/47ef500f4492c731ebfa33a12822ef6b5db4e7e2/nova/compute/manager.py#L7759
We should probably call a cleanup hook into the ResourceTracker to
cleanup those entries as well.
