[magnum] error when trying to overwrite master_lb_enabled in cluster create
by Ionut Biru 19 Oct '20

19 Oct '20

Hi guys, In template i have master_lb_disabled and i want to overwrite this option using: » openstack coe cluster create cluster002 --cluster-template b7e0be01-bf3b-4c32-af60-98b9edefa0be --keypair ioni --master-count 2 --node-count 2 --master-lb-enabled master_count must be 1 when master_lb_enabled is False (HTTP 400) (Request-ID: req-608b8634-d98e-4efd-b0e4-543ebc9eb315 Looking at the code https://opendev.org/openstack/magnum/src/branch/master/magnum/api/controlle… https://opendev.org/openstack/magnum/src/branch/master/magnum/api/attr_vali… It seems that the validator doesn't take in consideration the new cluster dictionary. I've modified the validator with: cluster.get('master_lb_enabled', cluster_template['master_lb_enabled']): and it seems to work fine Not sure if it is the right fix. -- Ionut Biru - https://fleio.com

approach to deploying rhosp 16.1 with octavia on standalone
by Chen Sagi 19 Oct '20

19 Oct '20

Hi, I am trying to figure out if I am able to deploy Red Hat Openstack platform with one physical server available, included with the Octavia solution. For now I have been trying to use the "openstack triplo deploy -standalone" command (with various environment files) and it Is unable to install Octavia without an undercloud available. Is it even possible? If so, I would love to hear some suggestions. Thanks, Chen Sagi.

What do you mean by "updating the respective table"? The optimal way to update a volume with a volume type is: 1) create a volume type pointing to the backend in which the volume currently is 2) retype the volume to that volume type > I have also defined a different volume type in > cinder.conf but I don't think you can just delete the __DEFAULT__ > type, The functionality to delete the __DEFAULT__ type is only available since cinder train >= 15.4.0 (See the releasenotes for more info regarding the __DEFAULT__ type[1]) Also you need to have a valid value defined with ``default_volume_type`` in cinder.conf Let me know if you have respective settings and still not able to delete the __DEFAULT__ type. > I'm not sure anymore but I think I also tried that.

Sorry for the stupid question... it’s been a while
by Florian Rommel 18 Oct '20

18 Oct '20

Hey everyone. So, I have developed openstack, wrote installers and fixed parts in the raw phytonutrients.. but... so I am , for fun and refreshing my memory, building an openstack deployment by hand, the hood old fashioned way. I have a few servers and I get everything working perfectly EXCEPT neutron ovs with dvr integration. I am using Ubuntu focal with ussuri release. When I deploy neutron i get the agents to show up and register with UP. The neutron-openvswitch-agent crashes with physical network floating to br-public not found. I am wondering how in need to configure the bridge in order to make this work. I have a empty interface (internet facing) which I added to br-public but where do I define the floating network name? Yes it’s stupid but I been banging my head against the wall:) Thanks already for help and sorry to anyone else for the dumb question:) //Florian

[ops] [cinder] __DEFAULT__ volume type
by Massimo Sgaravatto 17 Oct '20

17 Oct '20

I have recently updated my Cloud from Rocky to Train (I am running Cinder v. 15.4.0) I have a question concerning the __DEFAULT__ volume type, that I don't remember to have seen before. Since: - I have no volumes using this volume type - I defined in in the [DEFAULT] section of cinder.conf the attribute "default_volume_type" to a value different than "__DEFAULT___" I assume that I can safely delete the __DEFAULT__ volume type Is this correct? Thanks, Massimo

Register here: https://october2020ptg.eventbrite.com <https://october2020ptg.eventbrite.com/> FINAL SCHEDULE The final schedule [1] for the event is set here and in the PTGBot [2].

The main PTG IRC channel is #openstack-ptg on Freenode. It's used to interact with the PTGbot, and Foundation staff will be present to help answer questions. PTGBOT The PTGbot [3] is an open source tool that PTG track moderators use to surface what's currently happening at the event. Track moderators will send messages to the bot via IRC, and from that information, the bot publishes a webpage with several sections of information: - The discussion topics currently discussed in the room ("now") - An indicative set of discussion topics coming up next ("next") - The schedule for the day with available extra slots you can book Learn more about the ptgbot via the documentation here [4]. HELP DESK We are here to help! If you have any questions during the event week, we encourage you to join the #openstack-ptg IRC channel and ask them there. You can ping Kendall Waters (wendallkaters) and Kendall Nelson(diablo_rojo) directly on IRC. We will also have a dedicated Zoom room, but ONLY FOR MONDAY, October 26 where an OSF staff member will be available to answer your event related questions. You can also always reach someone at ptg(a)openstack.org if you are unable to connect to IRC. FEEDBACK We have preemptively created an etherpad[5] to collect all of your feedback throughout the event. Please add your thoughts as the week goes on. GAME TIME! Since we all know that coming together as a community to hang out and play games is part of what makes the PTG great, we are going to try something new this time around. This PTG, we are going to have two 'game nights'- obviously time zones are hard and it might not be night for everyone, but the times are as follows. - Thursday, October 29 at 19:00 UTC - Friday, October 30 at 10:00 UTC - Friday, October 30 at 23:00 UTC If you are interested in participating, write your name in the etherpad [6]. We will use it to coordinate games for each of the timeslots.
