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 Cheers, Kieran Kieran > > Vish > > [1] > http://lists.openstack.org/pipermail/openstack-dev/2014-February/027574.html > [2] https://bugs.launchpad.net/nova/+bug/1299517 > > On May 27, 2014, at 12:19 PM, Day, Phil > <[email protected]<mailto:[email protected]>> wrote: > >> Hi Vish, >> >> I think quota classes have been removed from Nova now. >> >> Phil >> >> >> Sent from Samsung Mobile >> >> >> -------- Original message -------- >> From: Vishvananda Ishaya >> Date:27/05/2014 19:24 (GMT+00:00) >> To: "OpenStack Development Mailing List (not for usage questions)" >> Subject: Re: [openstack-dev] [nova] nova default quotas >> >> Are you aware that there is already a way to do this through the cli using >> quota-class-update? >> >> http://docs.openstack.org/user-guide-admin/content/cli_set_quotas.html (near >> the bottom) >> >> Are you suggesting that we also add the ability to use just regular >> quota-update?
