Hi list,
I'm working under CentOS + icehouse.
I have created a private network with a subnet:
neutron net-list
+--------------------------------------+------+-----------------------------------------------------+
| id | name | subnets
|
+--------------------------------------+------+-----------------------------------------------------+
| c4f961d1-ac22-47d7-8edd-0829420c35cc | net |
b488f9c7-f4e0-4bb5-a648-b5da343fb138 172.16.24.0/24 |
+--------------------------------------+------+-----------------------------------------------------+
neutron subnet-list
+--------------------------------------+-------------+----------------+---------------------------------------------------+
| id | name | cidr |
allocation_pools |
+--------------------------------------+-------------+----------------+---------------------------------------------------+
| b488f9c7-f4e0-4bb5-a648-b5da343fb138 | flat_subnet | 172.16.24.0/24 |
{"start": "172.16.24.10", "end": "172.16.24.253"} |
+--------------------------------------+-------------+----------------+---------------------------------------------------+
Well, everything works fine, I can create instances with the network, and can
connected to instances as well.
But, then I noticed a small issue:
Every time, when I create a new instance, the IP address the instances get
keeps increasing.
For example, I create instance A, it's IP is 172.16.24.12.
Then I delete instance A, then create instance B, instance B's IP would be
172.16.24.13.
When I working under Havana, instance B would get 172.16.24.12.
Then I went to database and did a simple check:
mysql> select * from ipallocationpools;
+--------------------------------------+--------------------------------------+--------------+---------------+
| id | subnet_id |
first_ip | last_ip |
+--------------------------------------+--------------------------------------+--------------+---------------+
| d84f82c7-3815-4b61-9ba7-32522656a8d3 | b488f9c7-f4e0-4bb5-a648-b5da343fb138 |
172.16.24.10 | 172.16.24.253 |
+--------------------------------------+--------------------------------------+--------------+---------------+
1 row in set (0.00 sec)
mysql> select * from ipallocations;
+--------------------------------------+--------------+--------------------------------------+--------------------------------------+
| port_id | ip_address | subnet_id
| network_id |
+--------------------------------------+--------------+--------------------------------------+--------------------------------------+
| 331461c5-7f9f-484d-8136-f7c2ea044d2c | 172.16.24.11 |
b488f9c7-f4e0-4bb5-a648-b5da343fb138 | c4f961d1-ac22-47d7-8edd-0829420c35cc |
| 4b070d15-e96c-44a0-a3eb-2086066ed580 | 172.16.24.43 |
b488f9c7-f4e0-4bb5-a648-b5da343fb138 | c4f961d1-ac22-47d7-8edd-0829420c35cc |
+--------------------------------------+--------------+--------------------------------------+--------------------------------------+
2 rows in set (0.00 sec)
mysql> select * from ipavailabilityranges;
+--------------------------------------+--------------+---------------+
| allocation_pool_id | first_ip | last_ip |
+--------------------------------------+--------------+---------------+
| d84f82c7-3815-4b61-9ba7-32522656a8d3 | 172.16.24.44 | 172.16.24.253 |
+--------------------------------------+--------------+---------------+
1 row in set (0.00 sec)
As you can see, ipavailabilityranges is narrowing down.
Shouldn't it include 2 parts? 172.16.24.10 & 172.16.24.12-172.17.24.41 &
172.16.24.44 - 172.16.24.253.
Because only 2 IPs are actually using.
I'm worried if I created more instances, even I deleted them all at end, there
would still be no IP available at all.
Anyone know why this is happening ??
Is this a real issue ?
Thanks.
