[ussuri][tripleo][ironic][tftp] add --blocksize to tftp during installation
by Ruslanas Gžibovskis 20 May '21

20 May '21

Hi all, I wanted to ask, is there an option in tripleO to deploy undercloud tftp server with additional option, I had to add it to /usr/share/openstack-tripleo-heat-templates/deployment/ironic/ironic-pxe-container-puppet.yaml, so my container start cmd looks like this now: tripleoussuri/centos-binary-ironic-pxe:current-tripleo /bin/bash -c BIND_HOST=$(hiera ironic::pxe::tftp_bind_host -c /etc/puppet/hiera.yaml); /usr/sbin/in.tftpd --foreground --user root --address $BIND_HOST:69 --blocksize 1399 --m ap-file /var/lib/ironic/tftpboot/map-file /var/lib/ironic/tftpboot ironic_pxe_tftp But I believe it should be possibility with ExtraConfigUndercloud? I know, our network better should be fixed, but it will take several decades :) and while it will be fixed I want to automate deployment and it should be upgrade resistant :) Thanks for the advice in advance. -- Ruslanas Gžibovskis +370 6030 7030

[TripleO] tripleo-ci-centos-8-containers-multinode now using ephemeral Heat for master/wallaby
by James Slagle 20 May '21

20 May '21

For awareness, I wanted to point out that tripleo-ci-centos-8-containers-multinode is now using ephemeral Heat on the master and wallaby branches. This change[1] merged yesterday that made the switch. Of note, the Heat logs for the overcloud deployment are now under the directory undercloud/home/zuul/overcloud-deploy/overcloud/heat-launcher/log in the job logs. There is also a pending docs patch that covers a bit more how the feature works: https://review.opendev.org/c/openstack/tripleo-docs/+/783008 [1] https://review.opendev.org/c/openstack/tripleo-quickstart/+/777108 -- -- James Slagle --

[all][qa][cinder][octavia][murano] Devstack dropping support for Ubuntu Bionic 18.04
by Ghanshyam Mann 19 May '21

19 May '21

Hello Everyone, As per the testing runtime since Victoria [1], we need to move our CI/CD to Ubuntu Focal 20.04 but it seems there are few jobs still running on Bionic. As devstack team is planning to drop the Bionic support you need to move those to Focal otherwise they will start failing. We are planning to merge the devstack patch by 2nd week of May. - https://review.opendev.org/c/openstack/devstack/+/788754 I have not listed all the job but few of them which were failing with ' rtslib-fb-targetctl error' are below: Cinder- cinder-plugin-ceph-tempest-mn-aa - https://opendev.org/openstack/cinder/src/commit/7441694cd42111d8f24912f03f6… python-cinderclient - python-cinderclient-functional-py36 - https://review.opendev.org/c/openstack/python-cinderclient/+/788834 Octavia- https://opendev.org/openstack/octavia-tempest-plugin/src/branch/master/zuul… Murani- murano-dashboard-sanity-check -https://opendev.org/openstack/murano-dashboard/src/commit/b88b32abdffc171e6650450273004a41575d2d68/.zuul.yaml#L15 Also if your 3rd party CI is still running on Bionic, you can plan to migrate it to Focal before devstack patch merge.

Re: Freenode and libera.chat
by Gaël THEROND 19 May '21

19 May '21

Big +1 on my side too. Honestly, as someone else told it badly already, IRC is a nightmare to set and manage for anyone not coming from the 80/90s age of the internet. I do personally use it since decades and so I’m used to it BUT It’s not because I know how to use it that I’ll hide the truth. IRC and any client for it is challenging for any new comers. No, people don’t have to once again read and learn another tool just for our community. We’re in 2021 and things have improved a lot in terms of messaging systems, rich exchanges platforms emerged (With many opensource) and so I consider (as many others I bet) that as a community looking for diversity and inclusion it’s time to bring the community of existing and new contributors better tools, the messaging system revamp being one of the most important one to be reworked. I’m supporting (With another person from the internet) a small discord server of around 50 members and trying to answer many questions on reddit. Why did we setup such alternative? Because most of those people were young students thriving to get straight answers and support from the community. Why did they didn’t easily found answers? Because IRC channels are most of time dead towns (except for the kolla one) and that for people starting to learn Openstack it’s challenging to get access to IRC as it’s not as straightforward and feature rich as what alternatives messaging solutions can provide. It’s a matter of UI/UX, time consumed and amount of knowledge required to acquire just for one slightly simple/quick question. Same thing with the list by the way. I deeply think that if we want to continue to embark more new comers we will need alternatives for current communication platforms such as the IRCs channels and the list. Those are tools from the past. Sure they’re efficient, sure many of us know how to manage them but I really feel like adding another step to people trying to jump in isn’t a good way to welcome them. I perfectly know that some of us found it interesting as it kind of gates from «moronic» questions and it’s kind of seen as way to mark a tribal validation of your effort to join us, but in the meantime I think we’re loosing opportunities to bring more peoples in. It’s like in the real life, you’ll never want to use a tool or help someone that actually require you to follow a long and painful process before being able to help or use it. Sorry for the long message but I really wanted to explain the issue with those tools as one of my concerns actually surfaced today. PS: I don’t want us to join on Discord or any «SaaS solution » we can definitely host our own opensource alternative if we really want to gain autonomy on such topic.

[xena][neutron][ovn] Follow up to BGP with OVN PTG discussions
by Dan Sneddon 18 May '21

18 May '21

Thank you all who attended the discussions at the Xena PTG regarding BGP dynamic routing with Neutron using OVN. Here's a brief summary of the important points covered, and some background information. Red Hat has begun gathering a team of engineers to add OpenStack support for BGP dynamic routing using the Free Range Routing (FRR) set of daemons. Acting as a technical lead for the project, I led one session in the TripleO room to discuss the installer components and two sessions in the Neutron room to discuss BGP routing with OVN, and BGP EVPN with OVN. There was some feedback during the Neutron sessions that little has been done to engage the greater OpenStack/Neutron community thus far, or to utilize the existing RFE process for Neutron. This feedback was correct and was received. Initial work was done with a design that didn't require changes on Neutron/core OVN to start with. The intention is to create Neutron RFEs and to work with others working along similar lines now that we have some more clarity as to the direction of further efforts. There will likely be opportunities to leverage APIs and contribute to existing work being done with Neutron Dynamic Routing, BGPVPN, and other work being done to implement BGP EVPN. We would like to collaborate with Ericsson and others and come up with a solution that fits us all! The first steps involved greater changes to the deployment tooling, and this was proposed and reviewed upstream in the TripleO project: _ https://specs.openstack.org/openstack/tripleo-specs/specs/wallaby/triplo-bg… There are several use cases for using BGP, and in fact there are separate efforts underway to utilize BGP for the control plane and data plane. BGP may be used for equal-cost multipath (ECMP) load balancing of outbound links, and bi-directional forwarding detection (BFD) for resiliency to ensure that a path provides connectivity. For outbound connectivity BGP will learn routes from BGP peers. There is separate work being done to add BFD support for Neutron and Neutron Dynamic Routing, but this does not provide BFD support for host communication at the hypervisor layer. Using FRR at the host level provides this BFD support. BGP may be used for advertising routes to API endpoints. In this model HAProxy will listen on an IP address and FRR will advertise routes to that IP to BGP peers. High availability for HAProxy is provided via other means such as Pacemaker, and FRR will simply advertise the virtual IP address when it is active on an API controller. BGP may also be used for routing inbound traffic to provider network IPs or floating IPs for instance connectivity. The Compute nodes will run FRR to advertise routes to the local VM IPs or floating IPs hosted on the node. FRR has a daemon named Zebra that is responsible for exchanging routes between routing daemons such as BGP and the kernel. The redistribute connected statement in the FRR configuration will cause local IP addresses on the host to be advertised via BGP. Floating IP addresses are attached to a loopback interface in a namespace, so they will be redistributed using this method. Changes to OVN will be required to ensure provider network IPs assigned to VMs will be assigned to a loopback interface in a namespace in a similar fashion. FRR was selected for integration into TripleO and OVN for several reasons: using FRR leverages a proven production-grade routing solution that gives us BGP, BFD (bi-directional forwarding detection), VRFs for different namespaces for multitenancy, integration with kernel routing, and potentially other features such as OSPF, RPKI, route monitoring/mirroring, and more. FRR has a very complete feature set and is very robust, although there are other BGP speakers available such as ExaBGP or BIRD, and os-ken, with varying feature sets. OVN will need to be modified to enable the Compute node to assign VM provider network IPs to a loopback interface inside a namespace. These IP address will not be used for sending or receiving traffic, only for redistributing routes to the IPs to BGP peers. Traffic which is sent to those IP addresses will be forwarded to the VM using OVS flows on the hypervisor. An example agent for OVN has been written to demonstrate how to monitor the southbound OVN DB and create loopback IP addresses when a VM is started on a Compute node. The OVN changes will be detailed in a separate OVN spec. Demonstration code is available on Github: _ https://github.com/luis5tb/bgp-agent BGP EVPN with multitenancy will require separate VRFs per tenant. This will allow separate routing tables to be maintained, and allow for overlapping IP addresses for different Neutron tenant networks. FRR may have the capability to utilize a single BGP peering session to combine advertisements for all these VRFs, but there is still work to be done to prototype this design. This may result in more efficient BGP dynamic updates, and could potentially make troubleshooting more straightforward. As suggested in the PTG discussions, we are investigating the BGPVPN API. It appears that this API will work well for this use case. Hopefully we can make significant progress during the Xena development cycle, and we will be able to define what needs to be done in subsequent cycles. Any thoughts, suggestions, and contributions are appreciated. If anyone would like to review the work that we've already published, there is a series of blog posts that Luis Tomas Bolivar made related to how to use it on OpenStack and how it works: - OVN-BGP agent introduction: https://ltomasbo.wordpress.com/2021/02/04/openstack-networking-with-bgp/ - How to set ip up on DevStack Environment: https://ltomasbo.wordpress.com/2021/02/04/ovn-bgp-agent-testing-setup/ - In-depth traffic flow inspection: https://ltomasbo.wordpress.com/2021/02/04/ovn-bgp-agent-in-depth-traffic-fl… Here are some relevant links to posts written by Luis Tomas Bolivar on the ovs-discuss mailing list: https://mail.openvswitch.org/pipermail/ovs-discuss/2021-March/051029.html https://mail.openvswitch.org/pipermail/ovs-discuss/2021-March/051031.html https://mail.openvswitch.org/pipermail/ovs-discuss/2021-March/051033.html -- Dan Sneddon | Senior Principal Software Engineer dsneddon(a)redhat.com | redhat.com/cloud dsneddon:irc | @dxs:twitter

[Nova] Meeting time poll
by Artom Lifshitz 17 May '21

17 May '21

Hey all, As discussed during the IRC meeting today, the Red Hat Nova team would like to know if it's possible to shift the IRC meeting to a different day and/or time. This would facilitate our own internal calls, but I want to be very clear that we'll structure our internal calls around upstream, not the other way around. So please do not perceive any pressure to change, this is just a question :) To help us figure this out, I've created a Doodle poll [1]. I believe the regular attendees of the IRC meeting are spread between Central Europe and NA West Coast, so I've tried to list times that kinda make sense in both of those places, with a couple of hours on each side as a safety margin. Please vote on when you'd like the Nova IRC meeting to take place. Ignore the actual dates (like May 10), the important bits are the days of the week (Monday, Tuesday, etc). This is obviously a recurring meeting, something that Doodle doesn't seem to understand. I've not included Mondays and Wednesdays in the list of possibilities, as they would not work for Red Hat Nova. You can also vote to keep the status quo :) The times are listed in UTC, like the current meeting time, so unfortunately you have to be mindful of the effects of daylight savings time :( Thanks in advance!

by ManuParra 17 May '21

Dear OpenStack community, I have encountered a problem a few days ago and that is that when creating new volumes with: "openstack volume create --size 20 testmv" the volume creation status shows an error. If I go to the error log detail it indicates: "Schedule allocate volume: Could not find any available weighted backend". Indeed then I go to the cinder log and it indicates: "volume service is down - host: rbd:volumes@ceph-rbd”. I check with: "openstack volume service list” in which state are the services and I see that indeed this happens: | cinder-volume | rbd:volumes@ceph-rbd | nova | enabled | down | 2021-04-29T09:48:42.000000 | And stopped since 2021-04-29 ! I have checked Ceph (monitors,managers, osds. etc) and there are no problems with the Ceph BackEnd, everything is apparently working. This happened after an uncontrolled outage.So my question is how do I restart only cinder-volumes (I also have cinder-backup, cinder-scheduler but they are ok). Thank you very much in advance. Regards.

Hello Guys, I've just upgraded from openstack queens to rocky and then to stein on centos 7. In my configuration I have router high availability. After the upgrade and rebooting each controller one by one I get the following errors on all my 3 controllers under /var/log/neutron/l3-agent.log http://paste.openstack.org/show/805407/ If I run openstack router show for for one of uuid in the log: http://paste.openstack.org/show/805408/ Namespace for router in present on all 3 controllers. After the controllers reboot,some routers lost their routing tables, but restarting l3-agent they went ok. Is it possible router ha stopped working? Any idea,please ? Ignazio

neutron-18.0.0 tenacity-7.0.0 Python-3.9.4 neutron-linuxbridge-agent exits with AttributeError: 'FileNotFoundError' object has no attribute 'returncode' neutron/plugins/ml2/drivers/linuxbridge/agent/arp_protect.py: .. @tenacity.retry( wait=tenacity.wait_exponential(multiplier=0.02), retry=tenacity.retry_if_exception(lambda e: e.returncode == 255), reraise=True ) .. Not a python programmer. But I guess it has something to do with Python39
