| sgw | Morning all | 12:49 |
| sgw1 | admin0: What's your question? I can try and help | 12:52 |
| *** sgw1 has quit IRC | 13:34 | |
| *** sgw1 has joined #starlingx | 13:35 | |
| *** rcw has joined #starlingx | 13:40 | |
| admin0 | sgw, i want to test out startlingx ( in a real deployment scenairo ) meaning fully redundant setup | 13:53 |
| admin0 | and want to know what recommendations are there | 13:53 |
| admin0 | for example, is cinder needed in edge ? | 13:55 |
| admin0 | https://docs.starlingx.io/deploy_install_guides/r3_release/bare_metal/dedicated_storage.html -- so i use one iso to setup controllers as well as computes .. | 13:57 |
| admin0 | worker - here this means hypervisors right ? | 13:58 |
| *** bengates_ has quit IRC | 14:05 | |
| *** bengates has joined #starlingx | 14:06 | |
| admin0 | so if i want to test all the failover and redundancy, i need 2 controllers + 2 compute + 2 storage = 6 in the main .. and then probably 1 controller + 1 worker in edge ? | 14:07 |
| *** bengates_ has joined #starlingx | 14:09 | |
| sgw1 | admin0: yes, that would be an approach, you only need the single ISO to install controller-0, once up controller-0 can be used to install and provision the second controller, storage and worker nodes. | 14:09 |
| sgw1 | Worker nodes are either bare metal or possibly a Virtual setup, but that's more for testing. | 14:11 |
| admin0 | and in terms of network .. pxe is straightforward .. for pxe and ssh, management network = storge (cinder/ceph) and monitoring , | 14:12 |
| admin0 | what network is east-west ( traffic between vms over vxlan) and what network is north-south ( from vms to outside the cloud) ? | 14:12 |
| *** bengates has quit IRC | 14:12 | |
| admin0 | also a question is .. unlike all other openstack projects that uses 3 controllers to prevent split brain situation, your docs only use 2 controllers .. how is HA achieved in this case and most imporant, how do you prevent a split brain situation ? | 14:15 |
| admin0 | also the docs say 2 controllers on (min ) requirement, but does not give a (recommended) requirement | 14:16 |
| admin0 | the OAM subnet .. is it equivalent to provider network ext-net ? | 14:17 |
| *** bengates has joined #starlingx | 14:17 | |
| sgw1 | admin0: I am not completely sure I understand the question, but I have created a local setup with 3 networks, one for OAM(Internal connection to controllers only), one for Mgnt,(between Controllers, workers and storage) and one for Data (between workers and storage only) | 14:17 |
| sgw1 | I guess it all depends on your actual needs and corporate polices. I was able to do that with all 2 NIC boxes | 14:18 |
| sgw1 | I am not a network topology person. | 14:19 |
| admin0 | :) | 14:19 |
| admin0 | ok | 14:19 |
| admin0 | basically i am using openstack-ansible and openstack-kolla for a long time now .. and interested to try this project out also | 14:20 |
| admin0 | to see where it fits | 14:20 |
| admin0 | say i have a public platform .. os OAM subnet a floating-ip network | 14:20 |
| sgw1 | If you want to keep it simple, you can start with the AIO-Duplex | 14:20 |
| admin0 | or it is just a network where the api and horizon etc lives | 14:20 |
| *** bengates_ has quit IRC | 14:21 | |
| admin0 | AIO is good for development/developers . i am operator .. so i am OK to try the most elaborate one down and see what it is about and how it works | 14:21 |
| admin0 | AIO is like installation and then i get a horizon UI ..and i can login and do stuff .. but that does not help in understanding how its deployed in production with vlans, routing etc | 14:21 |
| sgw1 | it's better to have a fixed IP for the OAM controllers since if you take one down the other comes up onthe fixed IP address | 14:22 |
| admin0 | ok | 14:22 |
| sgw1 | admin0: your correct. I am part of the development team so I come from a different approach. | 14:22 |
| sgw1 | Also, I have limited hardware and networking available compared to other folks on the team. There are others (maybe not reading) that might have better suggestions for Operators. | 14:23 |
| *** riuzen has joined #starlingx | 14:24 | |
| admin0 | so as a developer, how do you handle split brain .. assuming there is a network issue between the 2 controllers and both think they are master ? | 14:24 |
| admin0 | mysql galera needs 3 nodes min . | 14:25 |
| sgw1 | Sorry, not my area of responsibility, not sure about that one. If you can't get your answers via IRC, you can send an email to the starlingx-discuss@lists.starlingx.io email list, you will need to subscribe to beable to send a message. | 14:26 |
| admin0 | thanks ...looking into the archive now http://lists.starlingx.io/pipermail/starlingx-discuss/ | 14:27 |

| sgw1 | born2bake: I saw that, I will ping during the community meeting tomorrow morning | 17:12 |
| sgw1 | https://wiki.openstack.org/wiki/Starlingx/Meetings#7am_Pacific_-_Technical_Steering_Committee_.26_Community_Call | 17:12 |
| sgw1 | I am sorry it's taking a while for people to reply, we are trying to get the 4.0 release done and lots going on. | 17:13 |
| born2bake | sure, its totally fine. By any chance, do you know if software management upgrade will be implemented and finished in 4th release? | 17:14 |
| born2bake | Thus, I am wondering how do you upgrade your environment? If you started since 1.0 release, how do you upgrade it to 2/3/4? | 17:15 |
| sgw | Upgrade is supposed to be on the list, I am not sure of it's current status, currently no upgrade between earlier releases. Have to do a full re-install. | 17:18 |
| born2bake | okay, thank you | 17:19 |
| *** sgw1 has quit IRC | 17:34 | |
| born2bake | sgw also, wanted to ask who I can talk to about openstack in starlingx? | 17:36 |
