I have the latest Sahara version (sahara-2014.2.b3) installed with the following configuration:




    'dashboards': ('project', 'admin', 'settings', 'router', 'sahara',),




when I create a "Node Group template" I can see the "Floating IP Pool" and I can see these 2 options:

Do not assign floating IPs 

If I select ext-net, I get this error message:

Error: Floating IP pool 9de9b761-621d-454f-83d9-5f63aa71ca0d for node group 'master' not found

If I select " Do not assign floating IPs"

Then I can create the "Node Group template" and the Cluster template successfully. But when I start the cluster, i get the same error related to the floating ip:

Error: Node Group master is missing 'floating_ip_pool' field

Is there anything wrong with the config? Any help would be greatly appreciated.

Here's the error from sahara.log:

 DEBUG sahara.utils.api [-] Validation Error occurred: error_code=400, error_message=Node Group master is missing 'floating_ip_pool' field, error_name=MISSING_FLOATING_NETWORK bad_request /opt/sahara/local/lib/python2.7/site-packages/sahara/utils/

floating_ip_pool field is required when use_floating_ips=true. That's why you are getting error in case of "Do not assign floating IPs" selection.

The first error message is more tricky. Horizon uses neutron.Client().list_networks({'router:external': True}) to get list of available pools. Sahara uses nova.Client().networks.find(id=pool_id) that passthrough request to neutron. So, results must be pretty the same. Could you please check if you really have Floating IP pool with ID 9de9b761-621d-454f-83d9-5f63aa71ca0d. Is it accessible from the current tenant?

Yes I do have a floating ip pool with ID 9de9b761-621d-454f-83d9-5f63aa71ca0d which is pointing to th ext-net. I can start an instance and associate a floating ip using that pool on the current tenant.

Hi Alazarev, I found an issue that might be related to the problem I am seeing. You mentioned that " Sahara uses "nova.Client().networks.find(id=pool_id)" ....". When I run "nova network-list", i got an error message: ERROR (NotFound): Not Found (HTTP 404), do you think this is the reason why?

Problem solved.. Found out that the network extension on nova was not enabled. After enabling it by adding the os_networks on the osapi_compute_ext_list in nova.conf & restarting the nova-api, it worked. Thanks for the info that sahara uses novaclient, that gave me a idea on how to solve the issue.

I've filed to address that.
