A reservation is always created with an expiration time; by default, this expiration time is 86400 seconds (1 day) after the time at which the reservation is created. Expired reservations are deleted by the _expire_reservations() periodic task, which is defined on the scheduler. Thus, if a resource is reserved, but never committed or rolled back, it should continue to affect quota requests for approximately one day, then be automatically rolled back by the scheduler. -- Kevin L.

[openstack-dev] ask for usage of quota reserve
hi all, can anyone tell if we call quotas.reserve() but never call quotas.commit() or quotas.rollback(). what will happen? for example: 1. when doing resize, we call quotas.reserve() to reservea a delta quota.(new_flavor - old_flavor) 2. for some reasons, nova-compute crashed, and not chance to call quotas.commit() or quotas.rollback() /(called by finish_resize in nova/compute/manager.py)/ 3. next time restart nova-compute server, is the delta quota still reserved , or do we need any other operation on quotas? Thanks in advance -Eli. ps: this is related to patch : Handle RESIZE_PREP status when nova compute do init_instance(https://review.openstack.org/#/c/132827/) https://review.openstack.org/#/c/132827/ -- Thanks Eli Qiao(qia...@cn.ibm.com) ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
