[原]openstack-kilo--issue(十七) heat创建网络Quota exceeded for resources OverQuotaClient: resources.dmz_protected_network_sub

-----  1  -------

在使用heat创建网络的时候，报错如下

  INFO heat.engine.stack [-] Stack CREATE FAILED (mmsc_network_stack): Resource CREATE failed: OverQuotaClient: resources.dmz_protected_network: Quota exceeded for resources: ['network']
  INFO heat.engine.service [-] Stack create failed, status FAILED

问题点分析：是因为neutron的network数量进行了限制：

vim  /etc/neutron/neutron.conf

# quota_network =
quota_network =          //将默认的10改大，超过需要创建的网络数

重启neutron

]# systemctl restart neutron-dhcp-agent.service neutron-l3-agent.service neutron-metadata-agent.service neutron-openvswitch-agent.service neutron-server.service neutron-ovs-cleanup.service

在使用heat创建网络的时候，解决了网络数量问题依然报错如下：

 INFO heat.engine.stack [-] Stack CREATE FAILED (mmsc_network_stack): Resource CREATE failed: OverQuotaClient: resources.dmz_protected_network_sub: Quota exceeded for resources: ['subnet']
 INFO heat.engine.service [-] Stack create failed, status FAILED

问题分析，在报错中发现有dmz_protected_network_sub字样，查看子网络的个数是否没有达到需要创建的子网数量并进行修改：

vim  /etc/neutron/neutron.conf

# quota_subnet =
quota_subnet =         //修改subnet数量

# quota_port =
quota_port = 

# quota_vip =
quota_vip = 

重启neutron

]# systemctl restart neutron-dhcp-agent.service neutron-l3-agent.service neutron-metadata-agent.service neutron-openvswitch-agent.service neutron-server.service neutron-ovs-cleanup.service

解决了子网问题：依然报错如下：

 TRACE heat.engine.resource BadRequest: Bad router request: Cidr 10.68.125.0/ of subnet d498b539-9eba-4bfc-91cd-6370b781ba8a overlaps with cidr 10.68.125.0/ of subnet 7e8b4e32-423c-4d5a-b9ae-22cf2e9d3417

 INFO heat.engine.service [-] Stack create failed, status FAILED

查看报错说有两个子网重复了，检查yaml文件，果然有两个子网重复

修改为唯一的子网并删除创建失败的stack后，再重新heat创建，

重启neutron

]# systemctl restart neutron-dhcp-agent.service neutron-l3-agent.service neutron-metadata-agent.service neutron-openvswitch-agent.service neutron-server.service neutron-ovs-cleanup.service
