Hi. I'm trying to launch a cluster using sahara and it keeps failing.

2016-12-15 19:39:23.102 2785 WARNING sahara.service.heat.heat_engine [req-e3f6db45-87cc-491f-b6dd-031311c022a1 6abfef77e9984fc58bb5decc566d12c2 fda14487a68f436da7b55fe218798ea2 - - -] [instance: none, cluster: 28349417-acef-4b24-bc26-b77a6bd54cf9] Cluster creation rollback (reason: Heat stack failed with status Resource CREATE failed: NotFound: resources.vanilla-default-worker.resources[0].resources.floating_ip: Floating IP pool not found. (HTTP 404) (Request-ID: req-d7f8fd82-2b89-41b8-8720-30ee8d1097c6)

I think this is where it's going bad. this is my neutron net-list:

+--------------------------------------+------------------------+-----------------------------------------------------+

+--------------------------------------+------------------------+-----------------------------------------------------+

I attached all nodes to test-net, and made cluster networking with test-net. I have no problem launching other instances using this network and they seem to work fine. I tried to set all nodes with external network and made cluster networking with external network, it passes this phase but it shows issues with portbinding. So I should use this test-net, which is meant to be private network in cloud, but I don't know why it says that Floating IP pool is not found. Where should I be looking at to solve this issue?

Well, it sounds that you definition of that Heat stack includes attachment of floating IP (equivalent to floatingip-associate) and you don't have any. Assuming that you use Neutron for networking, that means your neutron floatingip-list is empty and there no Heat resource equivalent of floatingip-create that you do by taking IPs from external network. (side note: floating ip pool is a notion of nova-network, in Neutron it is rather manipulated in one-by-one manner and therefore it is 'set') I do understand that you might be thinking of connecting the instance(s) without floating IP by hooking up to external network, but your Heat stack definition contains floating IP stuff

Thanks for your answer. I was following the guide, so I'm not sure which part of configuration is telling to use which Heat stack. Where do I see which Heat stack it's trying to use to make a cluster now..?

I don't know anything about Sahara<->Heat stuff. But keywords are template ('yaml file) and Heat stack So heat template-show /stack-show will give you something about that, that might allow you to backtrack that to Sahara configuration

Hi. I just tried to use fixed ips by setting use_floating_ips=false and it now goes on, and stops again with Heat problem.. ha..
