AFAIK, quota will expire in 24 hours

               help='Number of seconds until a reservation expires'),

Best Regards!

Subject:	[openstack-dev] [nova][resend with correct subject prefix] 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
   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

ps: this is related to patch : Handle RESIZE_PREP status when nova compute
do init_instance(https://review.openstack.org/#/c/132827/)
