[Bug 1496893] [NEW] Unable to modify "IP Allocation pool" for public subnet from Horizon but can do it from CLI

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Running RedHat OSP7 with Kilo installed on my Nodes. T

he topology consist of :
1. Controller + Network
2. Compute1
3. Compute2

The CLI shows this for the public subnet :

[root@g07-controller-1 ~(keystone_admin)]# neutron subnet-list
+--------------------------------------+------+----------------+--------------------------------------------------+
| id                                   | name | cidr           | allocation_pools                                 |
+--------------------------------------+------+----------------+--------------------------------------------------+
| fefa2447-f5db-4ff6-afa9-a669385cfda4 |      | 10.30.118.0/27 | {"start": "10.30.118.10", "end": "10.30.118.20"} |
+--------------------------------------+------+----------------+--------------------------------------------------+
[root@g07-controller-1 ~(keystone_admin)]# 


Now from the CLI I am able to change the pool :

[root@g07-controller-1 ~(keystone_admin)]# neutron subnet-update --allocation-pool start=10.30.118.10,end=10.30.118.25 fefa2447-f5db-4ff6-afa9-a669385cfda4 
Updated subnet: fefa2447-f5db-4ff6-afa9-a669385cfda4
[root@g07-controller-1 ~(keystone_admin)]# neutron subnet-list
+--------------------------------------+------+----------------+--------------------------------------------------+
| id                                   | name | cidr           | allocation_pools                                 |
+--------------------------------------+------+----------------+--------------------------------------------------+
| fefa2447-f5db-4ff6-afa9-a669385cfda4 |      | 10.30.118.0/27 | {"start": "10.30.118.10", "end": "10.30.118.25"} |
+--------------------------------------+------+----------------+--------------------------------------------------+


When tried to do the same thing from Horizon, I was able to change and also got a success message but when I checked again the pool size had not changed.
