| mgoddard_ | hi saharans, I'd like to deploy sahara to deploy spark on baremetal. Is this possible in Ocata? | 12:50 |
| *** jeremyfreudberg has quit IRC | 12:52 | |
| *** tellesnobrega has quit IRC | 12:52 | |
| tosky | it should be possible to deploy on baremetal (in general) and it was tested in the past; I personally didn't manage to properly test it though | 12:52 |
| openstackgerrit | OpenStack Proposal Bot proposed openstack/sahara master: Updated from global requirements https://review.openstack.org/465377 | 12:53 |
| *** jeremyfreudberg has joined #openstack-sahara | 12:53 | |
| mgoddard_ | tosky: thanks. Is the support for baremetal implicit? i.e. use the correct flavor and it (should) just work? | 12:54 |
| tosky | that's the idea | 12:54 |
| *** shuyingya has joined #openstack-sahara | 12:54 | |
| mgoddard_ | tosky: great. In comparison, magnum has separate drivers for baremetal and VMs which isn't ideal. | 12:55 |
| mgoddard_ | tosky: I'll go back to reading the docs then have a crack at deploying it. Thanks for the quick response | 12:56 |
| tosky | mgoddard_: yep, there is a section about @How to run a Sahara cluster on bare metal servers" in the doc | 12:58 |
| mgoddard_ | tosky: that sounds useful, I guess I was being impatient :) | 12:59 |
| *** shuyingya has quit IRC | 13:00 | |
| tosky | that said, as it's not regularly tested in the CI, there may be some rough edges; if you manage to have it working and have suggestions, they are more than welcome | 13:00 |
| *** shuyingya has joined #openstack-sahara | 13:00 | |
| mgoddard_ | tosky: understood. I've been using ironic for a long time so quite used to the less well trodden baremetal path... Happy to contribute where I can | 13:04 |
| tosky | nice! | 13:04 |

| tellesnobrega | jeremyfreudberg, hey, how is the patch that fixes our neutron tests going? | 14:34 |
| jeremyfreudberg | um that patch "works", it just might be a little unstable | 14:35 |
| jeremyfreudberg | sometimes the heat stuff screws up | 14:35 |
| tosky | some specific codepath/functionality? | 14:40 |
| *** ukaynar has joined #openstack-sahara | 14:41 | |
| jeremyfreudberg | tosky, my last comment on that patchset explains it. this is the error: http://logs.openstack.org/78/466778/24/check/gate-sahara-dsvm-scenario-mod-wsgi-ubuntu-xenial-nv/a2763c7/console.html.gz#_2017-06-02_11_33_07_474925 | 14:41 |
| jeremyfreudberg | the get_attr hack in OS::Neutron::FloatingIPAssociation is where it gets tripped up | 14:42 |
| tellesnobrega | jeremyfreudberg, this doesn't always happens, but it happens often? | 14:43 |
| jeremyfreudberg | tellesnobrega, exactly, only sometimes | 14:43 |
| tellesnobrega | that sucks | 14:43 |
| jeremyfreudberg | (more often on the mod-wsgi job then on other jobs, but that's a coincidence, we think) | 14:43 |
| tosky | and the reason is still unknown? The message hints about multiple resources with the same name | 14:45 |
| tellesnobrega | jeremyfreudberg, can we use IDs as the error suggests? | 14:46 |
| tellesnobrega | and the name should be ' ' on this case? | 14:46 |
| jeremyfreudberg | my interpretation of the error was that the get_attr fails, so it returns empty string. then we see side-effect of python quirk, where the empty string is "in" all other strings, so no match | 14:47 |
| jeremyfreudberg | but like I say, we can use a pre-created port, the question is, will it break ironic, and how can we find out | 14:48 |
| tellesnobrega | jeremyfreudberg, but why get_attr fails here? | 14:49 |
| tellesnobrega | jeremyfreudberg, I have to take a look at the test, I will be back later, going to grab something to eat, then I will look at the test and we can talk more | 14:50 |
| *** esikachev has quit IRC | 14:50 | |

| jeremyfreudberg | so tosky, is there some way that we can "borrow" ironic from somewhere? | 15:54 |
| tosky | jeremyfreudberg: on the CI? I think only with a virtual driver | 15:56 |
| jeremyfreudberg | tosky, you mean Ironic-on-Devstack of creating VMs masquerading as bare metal? | 16:07 |
| tosky | jeremyfreudberg: yes, I think it's the only way on the (normal) gates | 16:07 |
| jeremyfreudberg | I might be able to try it out locally at some point. Otherwise, I assume the environment that we used to get Ironic support going in the first place (that Mirantis folks used) is long gone? | 16:13 |
| *** esikachev has joined #openstack-sahara | 16:17 | |
| tosky | we never had it on the CI, not even on the Sahara CI | 16:17 |
| tosky | it was local testing | 16:17 |
| jeremyfreudberg | that's what I mean, someone at Mirantis (it was before my time, so I am extrapolating heavily) must have had local testing | 16:18 |
| tosky | yes, I think NikitaKonovalov did it, and more recently esikachev, if I remember correctly | 16:19 |

| jeremyfreudberg | tellesnobrega, any thoughts? I talked to a heat guy, they don't see anything exactly wrong with our code / heat templates | 18:02 |
| tellesnobrega | jeremyfreudberg, not yet | 18:02 |
| jeremyfreudberg | I'm willing to take a leap of faith and use pre-created ports instead of the get_attr stuff, and verify any Ironic breakage later (hopefully no breakage) | 18:04 |
| tellesnobrega | how would this pre created ports work exactly, who creates them? just want to be sure about we are talking | 18:05 |
| jeremyfreudberg | tellesnobrega, by pre-created it just means explicitly defined by OS::Neutron::Port in the template, instead of implict just by OS::Nova::Server | 18:06 |
| jeremyfreudberg | we used to do this, but at the time that we stopped doing it, Ironic did not like this. But, it's possible that bug has been fixed on the Nova-side | 18:07 |
| tellesnobrega | this is on the sahara/service/heat/templates.py right? | 18:08 |
| tellesnobrega | _serialize_neutron_floating? | 18:08 |
| jeremyfreudberg | yep | 18:08 |
| *** lucasxu has quit IRC | 18:08 | |
| *** lucasxu has joined #openstack-sahara | 18:09 | |
| tellesnobrega | lets try this, write a patch using OS::Neutron::Port and we see how the test behaves | 18:10 |
| tellesnobrega | we can always come back from that, but we MUST check ironic before merging it... ironic integration is not something that we can afford to break | 18:10 |
| tellesnobrega | jeremyfreudberg, can you explain what is the problem between ironic and this part of the code? I never saw this | 18:11 |
| tellesnobrega | since you already did your research :) | 18:12 |
| jeremyfreudberg | I get most of my info from Vitaly, but I am basing my argument off of this commit: https://github.com/openstack/sahara/commit/bf09037919dbc71be2685fc9636346b9c4adaae1 | 18:13 |
| jeremyfreudberg | related bugs https://bugs.launchpad.net/sahara/+bug/1557066 and https://bugs.launchpad.net/nova/+bug/1544195 | 18:13 |
| openstack | Launchpad bug 1557066 in Sahara "[Ironic] Need use Nova for assotiate floating ip" [High,Fix released] - Assigned to Vitaly Gridnev (vgridnev) | 18:13 |
| tellesnobrega | vitaly is a great source of information | 18:13 |
| openstack | Launchpad bug 1544195 in heat "User can not provision ironic node via nova when providing pre-created port" [Undecided,Confirmed] | 18:13 |
| tellesnobrega | jeremyfreudberg, thanks I will read it all asap | 18:14 |
| tellesnobrega | but yeah, what do you think of the approach I proposed? | 18:14 |
| jeremyfreudberg | So, regarding your approach, if we try OS::Neutron::Port way instead of get_attr, most likely the tests will just succeed, since the port id will be explicitly contained by the template. (If it happens to fail, then that will tell us it is just general CI/devstack bugginess) But in all likelihood, the tests will pass but Ironic status will be unknown until someone tests it manually | 18:16 |
| *** ukaynar has quit IRC | 18:19 | |
| tellesnobrega | jeremyfreudberg, I understand, I don't have resources to test that, maybe if we can fake ironic, I will take a look into that | 18:20 |
| tellesnobrega | but send the patch so we can grab the version that we want to merge if ironic works with it | 18:20 |
| *** ukaynar has joined #openstack-sahara | 18:20 | |
| jeremyfreudberg | their devstack plugin has a way of doing a VM pretending to be baremetal, the question is will it behave exactly the same way | 18:20 |
| jeremyfreudberg | but yes, tellesnobrega, I will send the patch out | 18:21 |
| tellesnobrega | jeremyfreudberg, thanks, I will try and talk with ironic people see what they have to say about that | 18:21 |

| *** jeremyfreudberg has joined #openstack-sahara | 18:56 | |

| jeremyfreudberg | and then later we can try testing that on the Devstack/Ironic thing | 18:58 |
