Hey everyone, I'm hoping to get some feedback from folks, especially operators. In the Liberty release, Cinder introduced the ability to use a Nest Quota Driver to handle cases of heirarchical projects and quota enforcement [0]. I have not heard of anyone actually using this. I also haven't seen any bugs filed, which makes me a little suspicious given how complicated it can be. I would like to know if any operators are using this for nested quotas. There is an effort underway for a new mechanism called "unified limits" that will require a lot of modifications to the Cinder code. If this quota driver is not needed, I would like to deprecated it in Train so it can be removed in the U release and hopefully prevent some unnecessary work being done. Any feedback on this would be appreciated. Thanks! Sean [0] https://specs.openstack.org/openstack/cinder-specs/specs/liberty/cinder-nest...
