IMO we need to revert this removal as we (accidentally) removed a Havana feature with no notification to the community. I’ve reactivated a bug[2] and marked it critical. +1. We rely on this to set the default quotas in our cloud. Hi Kieran, Can you elaborate on this point. Do you actually use the full quota-class functionality that allows for quota classes, if so what provides the quota classes? If you only use this for setting the default quotas, why do you prefer the API and not setting the config file? We just need the defaults. My comment was more to indicate that yes, this is being used by people. I'm sure we could switch to using the config file, and generally I prefer to keep configuration in code, but finding out about this half way through a release cycle isn't ideal. I notice that only the API has been removed in Icehouse, so I'm assuming the impact is limited to *changing* the defaults, which we don't do often. I was initially worried that after upgrading to Icehouse we'd be left with either no quotas or whatever the config file defaults are, but it looks like this isn't the case. Unfortunately the API removal in Nova was followed by similar changes in novaclient and Horizon, so fixing Icehouse at this point is probably going to be difficult. *[Day, Phil] I think we should revert the changes in all three system then. We have the rules about not breaking API compatibility in place for a reason, if we want to be taken seriously as a stable API then we need to be prepared to roll back if we goof-up.* *Joe – was there a nova-specs BP for the change ? I’m wondering how this one slipped through* That's a good question. the API extension quota-classes has been around for a very long time and never actually worked [0]. This was brought up again in February 2014 and the original author chimed in saying it doesn't work [1]. When this came up there was no discussion around the default quota value functionality, and it didn't come up in any of the reviews. Because this was supposed to be just removing dead code there as no nova-specs BP for it.

I don't think we want a full revert here, the feature that we broke is the ability to easily update the default quota values without restarting any services, not quota-classes themselves. Given that I see 3 paths forward: 1. Provide an alternate way to do this. OpenStack already has an implicit assumption that one has a way of rolling out config files across all machines. so we can teach oslo.config to know which config options can be updated without a restart. While this definitely breaks the API, this is a rarely used API and we can avoid breaking functionality at least. 2. Do a partial revert of this API to only support overriding the default quota values. Hopefully while doing this we can simplify the quota logic and reduce the number of DB calls needed. This way we can restore the working part of the API and not the unimplemented quota-class logic itself. 3. Do a full revert and re-add all the unimplemented quota-class logic, we now have just re-added a non-working API. While I would prefer to take path 1 as I think that gets us closer to where we should be, I think path 2 is safer approach. Once that's merged I can work on backporting the revert for the API change to stable/icehouse, which will be a little tricky given conflicts from master.

Re: [openstack-dev] [nova] nova default quotas
Hi Kieran, What do you think about the approach proposed in https://review.openstack.org/#/c/94519/ ? What we are trying to do is to simplify the way to manage default quotas through an API and keeping backward compatibility. So doing this is not needed to restart any service once a default quota is changed, something that could be painful when there are many services running in parallel.

So doing this is not needed to restart any service once a default quota is changed, something that could be painful when there are many services running in parallel. If the current spec is implemented as-is, when we upgrade to Juno our default quotas will be wrong. Like Joe mentioned, the table wasn't dropped in Icehouse (and the underlying default quotas still work), so my only concern at this point is that users don't have to do *anything* in order to ensure that default quotas are maintained during an Icehouse - Juno upgrade. Whether this should happen as part of your spec, or another spec designed to address just this issue, I don't know.

IMO we need to revert this removal as we (accidentally) removed a Havana feature with no notification to the community. I’ve reactivated a bug[2] and marked it critcal. While I agree that we shouldn't have removed support for a working feature like updating the default quota via the REST API. I don't think we should just do a revert. The good news is we haven't dropped any tables yet, so a revert won't require any migrations. * quota-classes never worked for anything except changing default quotas, and this feature adds a whole bunch of DB calls to every quota lookup (a big overhead for a mostly broken feature). I am not a huge fan of bringing back a feature that is known to be mostly broken. I am also not a fan of breaking working features, which we did. Perhaps the right answer is to bring back just the default value override support. * But having a rest API to override config file options sounds like a step in the wrong direction. I can see this easily leading to confusion about where the default quota values are coming from. This is part of a larger issue: folks want to update config options without restarting any services, as far as I know there is no reason why we cannot support this with minimal changes in a way that we can use this for other config options.

I don’t think in the earlier ML thread[1] that anyone remembered that the quota classes were being used for default quotas. IMO we need to revert this removal as we (accidentally) removed a Havana feature with no notification to the community. I’ve reactivated a bug[2] and marked it critical. +1. We rely on this to set the default quotas in our cloud. Hi Kieran, Can you elaborate on this point. Do you actually use the full quota-class functionality that allows for quota classes, if so what provides the quota classes? If you only use this for setting the default quotas, why do you prefer the API and not setting the config file? We just need the defaults. My comment was more to indicate that yes, this is being used by people. I'm sure we could switch to using the config file, and generally I prefer to keep configuration in code, but finding out about this half way through a release cycle isn't ideal. I notice that only the API has been removed in Icehouse, so I'm assuming the impact is limited to *changing* the defaults, which we don't do often. I was initially worried that after upgrading to Icehouse we'd be left with either no quotas or whatever the config file defaults are, but it looks like this isn't the case. Unfortunately the API removal in Nova was followed by similar changes in novaclient and Horizon, so fixing Icehouse at this point is probably going to be difficult.
