(Being quite far from nova code, so ignore if not applicable) I would like to note that other services experience races in quota management too. Neutron has a spec approved to land in Kilo-3 that is designed to introduce a new quota enforcement mechanism that is expected to avoid (some of those) races: https://github.com/openstack/neutron-specs/blob/master/specs/kilo/better-quotas.rst I thought you may be interested in looking into it to apply similar ideas to nova. /Ihar -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBAgAGBQJVAMrNAAoJEC5aWaUY1u57aV8H/1jTSrpJYYRBH6hOrl2MlPNV mgH+sszhKDZbNjHAlIjCGqu4/Rzbf7Xhp1ujhzQFA54UcQ/cKSsao7kgHcAGJ7ib FHM8RIf0UNXw2KkvCc4gvrfEO0vxMkzWZ12RdtyKSJVxJgWNctnX6VI4f1ZS5mIb S5mrpPxVyL/Hplr+Yy05m4S7ALyiKGVogCYtRYqnBaH3IIK9Nve3hyfzcgBvd+h+ 9CfGeFX4WJr/JDGoDCNX/Zq9/SgVuEjm2fXgbZPaZDGoTc4RrrTe6TWi1g8mx/pD QuTsyUu3CvRAr2qafPS4c2j0qEaooCsA22A8Il8mvnO7Rp12KkxCWojkoPvFOpA= =JV5/ -----END PGP SIGNATURE----- __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
