Neutron RabbitMQ issues
by Grant Morley 20 Mar '20

20 Mar '20

Hi all, We are currently experiencing some fairly major issues with our OpenStack cluster. It all appears to be with Neutron and RabbitMQ. We are seeing a lot of time out messages in responses to replies and because of this instance creation or anything to do with instances and networking is broken. We are running OpenStack Queens. We have already tuned Rabbit for Neutron by doing the following on neutron: heartbeat_timeout_threshold = 0 rpc_conn_pool_size = 300 rpc_thread_pool_size = 2048 rpc_response_timeout = 3600 rpc_poll_timeout = 60 ## Rpc all executor_thread_pool_size = 64 rpc_response_timeout = 3600 What we are seeing in the error logs for neutron for all services (l3-agent, dhcp, linux-bridge etc ) are these timeouts: https://pastebin.com/Fjh23A5a We have manually tried to get everything in sync by forcing fail-over of the networking which seems to get routers in sync. We are also seeing that there are a lot of "unacknowledged" messages in RabbitMQ for 'q-plugin' in the neutron queues. Some times restarting of the services on neutron gets these back acknowledged again, however the timeouts come back. The RabbitMQ servers themselves are not loaded at all. All memory, file descriptors and errlang processes have plenty of resources available. We are also seeing a lot of rpc issues: Timeout in RPC method release_dhcp_port. Waiting for 1523 seconds before next attempt. If the server is not down, consider increasing the rpc_response_timeout option as Neutron server(s) may be overloaded and unable to respond quickly enough.: MessagingTimeout: Timed out waiting for a reply to message ID 965fa44ab4f6462fa378a1cf7259aad4 2020-03-10 19:02:33.548 16242 ERROR neutron.common.rpc [req-a858afbb-5083-4e21-a309-6ee53582c4d9 - - - - -] Timeout in RPC method release_dhcp_port. Waiting for 3347 seconds before next attempt. If the server is not down, consider increasing the rpc_response_timeout option as Neutron server(s) may be overloaded and unable to respond quickly enough.: MessagingTimeout: Timed out waiting for a reply to message ID 7937465f15634fbfa443fe1758a12a9c Does anyone know if there is anymore tuning to be done at all? Upgrading for us at the moment to a newer version isn't really an option unfortunately. Because of our setup, we also have roughly 800 routers enabled and I know that will be putting a load on the system. However these problems have only started to happen roughly 1 week ago and have steadily got worse. If anyone has any use cases for this or any more recommendations that would be great. Many thanks,

[release] Release countdown for week R-7, March 23-27
by Sean McGinnis 20 Mar '20

20 Mar '20

Development Focus ----------------- We are entering the last weeks of the Ussuri development cycle. From now until the final release, we'll send a countdown email like this every week. It's probably a good time for teams to take stock of their library and client work that needs to be completed yet. The non-client library freeze is coming up, followed closely by the client lib freeze. Please plan accordingly so avoid any last minute rushes to get key functionality in. General Information ------------------- Next week is the Extra-ATC freeze, in preparation for elections. All contributions to OpenStack are valuable, but some are not expressed as Gerrit code changes. Please list active contributors to your project team who do not have a code contribution this cycle, and therefore won't automatically be considered an Active Technical Contributor and allowed to vote. This is done by adding extra-atcs to https://opendev.org/openstack/governance/src/branch/master/reference/projec… before the Extra-ATC freeze on March 26. A quick reminder of the upcoming freeze dates. Those vary depending on deliverable type: * General libraries (except client libraries) need to have their last feature release before Non-client library freeze (April 2). Their stable branches are cut early. * Client libraries (think python-*client libraries) need to have their last feature release before Client library freeze (April 9) * Deliverables following a cycle-with-rc model (that would be most services) observe a Feature freeze on that same date, April 9. Any feature addition beyond that date should be discussed on the mailing-list and get PTL approval. After feature freeze, cycle-with-rc deliverables need to produce a first release candidate (and a stable branch) before RC1 deadline (April 23) * Deliverables following cycle-with-intermediary model can release as necessary, but in all cases before Final RC deadline (May 7) Finally, now is also a good time to start planning what highlights you want for your deliverables in the cycle highlights. The deadline to submit an initial version for those is set to Feature freeze (April 9). Background on cycle-highlights: http://lists.openstack.org/pipermail/openstack-dev/2017-December/125613.html Project Team Guide, Cycle-Highlights: https://docs.openstack.org/project-team-guide/release-management.html#cycle… knelson [at] openstack.org/diablo_rojo on IRC is available if you need help selecting or writing your highlights Note that cycle highlights are per-team, not per-deliverable. Upcoming Deadlines & Dates -------------------------- Extra-ATC freeze: March 26 (R-7 week) Non-client library freeze: April 2 (R-6 week) Client library freeze: April 9 (R-5 week) Ussuri-3 milestone: April 9 (R-5 week) Cycle Highlights Due: April 9 (R-5 week)

Hello All, I would like to suggest to modify the unity iscsi cinder driver documentation. After 1 month of intensive test, we discovered the mutipath.conf needs the following option in multipath.conf kvm nodes: skip_kpartx yes Without the above option instances with more than 2 volumes attached could fail live migration because the os_brick code fails in "multipath -f" command reporting map in use error.

[openstack.org] SEO Improvements
by Jimmy McArthur 19 Mar '20

19 Mar '20

Hi all - We've contracted a professional SEO firm to help improve search placement for all OSF projects. I'd like to crowd source this on each of the project mailing lists, so the community is able to be involved. Could you all help out in providing the below: “Wish List” of keywords: 8-12 big terms you think fit your domain (if you only have 4-5 to share, fewer is okay) - open source ci - ? At least 3 competitors - Jenkins - ? Any other input on positioning, offerings, etc. that you think will help best filter for relevance - ? Cheers, Jimmy

[nova] bug triage
by Balázs Gibizer 19 Mar '20

19 Mar '20

Hi, We surpassed the somewhat magical line of having more than 100 untriaged nova bugs [1]. For me it seems that how we, as a team, are handling the incoming bugs is not sustainable. I'm guilty as well of not doing bug triage in a last two months. So I'm personally trying to change now and dedicate a weekly times lot to look at the bug list. But I also want to open a discussion about bug triage in genera. How can we handle the incoming bugs? I see that neutron does a weekly rotation of bug deputy and for them it works nicely. What do you think? Do we want to try that? Do we have enough volunteers to create a nice rotation period? Cheers, gibi [1] https://bugs.launchpad.net/nova/+bugs?search=Search&field.status=New

[all][tc] Moving PTL role to "Maintainers"
by Mohammed Naser 19 Mar '20

19 Mar '20

Hi everyone: We're now in a spot where we have an increasing amount of projects that don't end up with a volunteer as PTL, even if the project has contributors .. no one wants to hold that responsibility alone for many reasons. With time, the PTL role has become far more overloaded with many extra responsibilities than what we define in our charter: https://governance.openstack.org/tc/reference/charter.html#project-team-lea… I think it's time to re-evaluate the project leadership model that we have. I am thinking that perhaps it would make a lot of sense to move from a single PTL model to multiple maintainers. This would leave it up to the maintainers to decide how they want to sort the different requirements/liaisons/contact persons between them. The above is just a very basic idea, I don't intend to diving much more in depth for now as I'd like to hear about what the rest of the community thinks. Thanks, Mohammed

[ops][cinder] deprecation notice: os-reset_status notifications
by Brian Rosmaita 19 Mar '20

19 Mar '20

tl;dr: the notifications themselves aren't being deprecated, there's a change in where they're being sent While working on https://launchpad.net/bugs/1863806, Walt discovered that notifications associated with the Block Storage API os-reset_status calls were being sent to nonstandard publisher_ids, namely: * 'volumeStatusUpdate' for volume status resets * 'volumeStatusUpdate' for snapshot status resets * 'backupStatusUpdate' for backup status resets Walt has a patch up to direct these notifications to the same publisher_id as other Cinder resource actions: * 'volume' for volume status resets * 'snapshot' for snapshot status resets * 'backup' for backup status resets Walt's patch continues to send the notifications to the nonstandard publisher_ids, but this behavior is DEPRECATED. In Ussuri, notifications will be sent to *both* publisher_ids. We propose to remove sending notifications to the nonstandard publisher_ids during the Victoria development cycle. This deprecation will be announced in the cinder release notes, but we wanted to give operators advance notice. No one currently working on cinder knows why these notifications were being sent to nonstandard publisher_ids, which makes it difficult to assess what, if any, impact this change will have on operators. If you have concerns about either the nonstandard publisher_ids being deprecated and removed, or about these notifications being sent to the standard publisher_ids, please express them on the following review before Tuesday 24 March: https://review.opendev.org/#/c/708563/ Thank you.

Not running for TC this round
by Thierry Carrez 18 Mar '20

18 Mar '20

Hi everyone, I've been elected on the TC (or its previous incarnations) since we had community-elected seats in that body (2011). However, as announced during the previous election round (and in the discussion about reducing the number of TC seats) I do not plan to run for the TC in the upcoming election round. There are multiple reasons for this. The main one is that with name recognition and a Condorcet voting system, it's relatively easy for incumbents to be reelected. We only elect 5 seats this time, so I think it's important to make room for new names to step up. The second reason is that I'd like more people with an operational background to be present on the TC. I think we can simplify our governance by having a single elected body handling the open source project, rather than maintain separate representation for users and developers. As we get more people bringing operational perspective to the TC, that simplification will be even more obvious. The final reason is that I've always been saying that you can work on governance issues and voice your opinion on them, without being elected on the TC and formally voting on things. It's time for me to walk that talk. I do not intend to go anywhere, and I'll be as present as always in proposing the OpenStack governance changes that I deem needed in this day and age. I'll finish this email by encouraging anyone interested in open source project governance, or wanting to help shape the next chapter of the OpenStack story, to step up and run for TC election. As for all governance bodies, the experience can be frustrating, as you'd like to fix more things but there is only so much you can do. But it's a great experience, one that I recommend everyone working on open source project should have. The only prerequisite is an interest and care for "OpenStack" as a whole. No specific experience or diploma needed. If you wonder if you can do it, the answer is yes. Nominations[1] open up March 24. Please consider running, especially if you have operational experience with some cycles to spare. If you have any questions on the job, feel free to reach out to me -- you know where to find me.

Using #opendev on Freenode for OpenDev Infrastructure Discussions
by Clark Boylan 17 Mar '20

17 Mar '20

Hello all, We have reached a point in time where it now makes sense for us to use #opendev on Freenode for OpenDev discussions, rather than #openstack-infra. We are updating our various bots to reflect this change and are asking you to find us in the new channel. We expect this to be a time of transition so don't be afraid of bringing things up in either the old or new channel if you are unsure of where you should go; we'll get you pointed in the right direction. The old channel, #openstack-infra, won't be going away. We expect it to become more OpenStack specific. Topics like how to use Zuul for OpenStack jobs could go here. This likely will have some overlap with the #openstack-qa channel and we may end up collapsing them, but that can happen if we notice the conversations do overlap significantly. We hope this gives non OpenStack users a friendly neutral location to engage us. Sorry, for any disruptions this may cause. Clark

[all] Guides for newbies to OpenStack
by Mike Carden 17 Mar '20

17 Mar '20

Our small team at ${DAYJOB} has built a handful of OpenStack clusters based on Red Hat OpenStack 13 (aka Queens) over the last couple of years. We now find ourselves in the position of being 'gifted' human resources in the shape of mid-level 'IT people' who are sent to join our team for a short time to 'Learn OpenStack'. These tend to be people for whom, "Here's a Horizon URL and some creds - go log in and launch a VM"[1]... is a bit much. I've done a wee bit of web searching (enough to find the dead links) trying to find some newbie friendly tutorials on OpenStack basics. Before I attempt to re-invent the wheel, can anyone suggest some public resources I might point people to? Deity help us if we have to explain Tripleo's Undercloud, Overcloud, partially containered, partially pacemakered, fully flaky... underpinnings. Thanks, MC [1] Even with a step by step guide

[tc][requirements][horizon] Broken gates due to the new setuptools and pyScss package
by Ivan Kolodyazhny 17 Mar '20

17 Mar '20

Hi team, I'm sorry for being too noisy, but I decided to tag TC to get more attention to the current Horizon situation. We've got a bug reported by Kolla team two days ago [1]. We merged some workaround [2] and [3] yesterday. Thanks a lot to the Requirements team for the really quick merge! I appreciate it. For now, we've got horizon gates broken because of hose patches fix only devstack but not unit tests jobs. The root cause of this situation is pyScss package which is not maintained for the last two years. It's not a surprise to me that it doesn't work with the new setuptools. I'm really surprised that we've found this kind of bugs only now. Since I don't believe we can block new setuptools forever, I decided to fork pyScss [4] and django-pyscss [5] projects. I'm still not sure that I've done everything right with licensing and versioning, but it works now on my environment. Any help on these areas would be much appreciated. I proposed patches to requirements and horizon repos [6] to use new libraries. The reason I've tagged TC in the mail thread is described below. Horizon has a lot of too old and unmaintained libraries. I'm pretty sure that this only one of the first issues with outdated dependencies which blocks horizon and other gates. I do understand why we've got this situation. Unfortunately, we don't have any full-time horizon developers in the community. Horizon is mostly in maintenance phrase but not in active development. I would like to get more attention on this issue because we have to update all dependencies not because they are new, have new features and/or security fixes. We have to take care of our dependencies asap to avoid usage of unmaintained libraries to have the whole OpenStack and Horizon healthy. P.S. I'm sorry if this message is too rude or emotional, I really don't want to make it such one.

PyOS

Dear OpenStack devs, Just a quick question: I came across your project 'pyos' on pypi after using this name for internally one of my projects. I see that you haven't updated the package for some time and was wondering if it was dead and if so if you would consider transfering the name to me for hosting my project? Thanks for your time. All the best, -Martin

[ironic] proposing Iury Gregory for bifrost-core, ironic-inspector-core, sushy-core

Iury has been working hard across the ironic community and has been quite active in changing and improving our CI, as well as reviewing code contributions and helpfully pointing out issues or items that need to be fixed. I feel that he is on track to join ironic-core in the next few months, but first I propose we add him to bifrost-core, ironic-inspector-core, and sushy-core. Any objections?

[ops] how to setup bgp-to-the-host and Neutron Dynamic Routing ?
by Thomas Goirand 16 Mar '20

16 Mar '20

Hi, In my setup, the bgp-to-the-host part is already operational. We're using IPv6 local link to 2 switches on each host, each of them advertising for itself to both routers. Now, I'm trying to add Neutron stuff to it. In my setup, I don't have any IPv4 on my nics, both have ipv6 local link only. So, where do I connect br-ex? I don't have a bond0 interface to connect to anymore... Then, we do have an FRR instance to do the bgp-to-the-host IPv4 routing on each host. How does this work on the hosts where the dr-agent is running? Can it re-use the FRR that I've setup to do the route advertisements too? Or do I need another instance of a routing daemon? Cheers, Thomas Goirand (zigo)

[Tempest] OpenSack Powered * vs OpeStack Compatible
by prakash RAMCHANDRAN 16 Mar '20

16 Mar '20

Hi all, I am curious to find out if any Distribution or Products based on Openstack Train or Usuri are seeking the latest certifications based on 2019.02. Similarly does any Hardware Driver of Software application seeking OpenStack compatibility Logo? Finally does anyone think that Open Infra Distro like Airship or StarlingX should promote Open Infra Airship or Open Infra StarlingX powered as a new way to promote eco system surrounding them similar to OpenStack compatible drivers and software. Will then Argo, customize, Metal3.io or Ironic be qualified as Open Infra Airship compatible? If so how tempest can help in testing the above comments? Refer to this market place below as how Distos and Products leverage OpenStack logos and branding programs. https://www.openstack.org/marketplace/distros/ Discussions and feedback are welcome. A healthy debate as how k8s modules used in Open Infra can be certified will be a good start. ThanksPrakash Sent from Yahoo Mail on Android

Hi all, During CentOS 8 dependencies preparation we've built ansible 2.9 in RDO dependencies repo which was released on Oct 2019, While testing TripleO with CentOS8 it has been discovered that the latest release of ceph-ansible does not support ansible 2.9 but only 2.8, so I'm opening discussion about the best way to move on in CentOS 8: - Make ceph-ansible 4.0 to work with ansible 2.8 *and* 2.9 so that the same releases can be used in CentOS7 with Stein and Train and CentOS8 Train and Ussuri. - Maintain separated ceph-ansible releases and builds for centos7/ansible 2.8 and centos8/ansible 2.9 able to deploy Nautilus. - Move ansible back to 2.8 in CentOS 8 Ussuri repository. I wonder if TripleO or other projects using ansible from RDO repositories has any requirement or need to move to ansible 2.9 in Ussuri cycle or can stay in 2.8 until next release, any thoughts? Best regards, Alfredo

[requirements][all] migration OFF of mock to the unittest.mock built-in library
by Matthew Thode 13 Mar '20

13 Mar '20

I'd like to suggest, now that we are on modern python, that we stop using the mock library and instead use the built in mock library. unittest.mock has been around since python-3.3 so we should not have a problem with python support. This would allow us to drop a library and also help prevent issues with stuff like https://review.opendev.org/712713 is going to expose (nova/neutron fail tests with the external mock-4 library). -- Matthew Thode

[requirements] add sqlalchemy-filters
by Prashant Bhole 13 Mar '20

13 Mar '20

Hello requirements people, I wanted to discuss about addition of this new requirement: sqlalchemy-filters https://pypi.org/project/sqlalchemy-filters/ Why it is needed: This library is used in Tacker project for the implementation of Attribute Filtering of VNF Packages defined in ETSI NFV_SOL005 section 9.4.2.3.2. It is used for adding filter criterion to SQL alchemy queries. These criterion are based on attribute values of VNF Packages passed in the GET request to list VNF Packages. This library can be reused for similar cases in future. Matthew Thode had raised a concern about this project being stale as there are pending PRs. On contacting with the developer of the library the developer said that he will will work on pending PRs. The project is being actively maintained. Please review it. https://review.opendev.org/#/c/710555/ Thanks, Prashant

[neutron] Propose Lajos Katona for Neutron core team
by Slawek Kaplonski 13 Mar '20

13 Mar '20

Hi neutrinos, I would like to propose Lajos Katona (irc: lajoskatona) as a member of the Neutron core team. Lajos is Neutron contributor Neutron since around Queens cycle and now he is one of the most active reviewers in the Neutron group projects. He was one of the key contributors in cooperation with Nova and Placement teams to deliver guaranteed minimum bandwidth feature in OpenStack. He is very active and helpful with triaging and fixing Neutron bugs and issues in our CI. During last few cycles he proved that he has wide knowledge about Neutron code base. He is currently also a maintainer of some neutron stadium projects which shows that he has knowledge about code base not only about neutron but also Neutron stadium. The quality and number of his reviews are comparable to other members of the Neutron core team: https://www.stackalytics.com/?release=ussuri&module=neutron-group and are higher every cycle :) I think he will be great addition to our core team. I will keep this nomination open for a week or until all current cores will respond. — Slawek Kaplonski Senior software engineer Red Hat

[API][SDK][SIG] distilling our community wisdom
by Michael McCune 13 Mar '20

13 Mar '20

hello all, given the recent trend of discussing how we can condense and streamline various parts of the openstack community, i would like to start socializing the idea of merging the API-SIG, and its artifacts/processes/members, with the SDK group. over the last few years we have seen the activity of the API SIG greatly reduced. although there are a few outstanding guidelines that should be merged, we are having fewer and fewer contributors. additionally, although we migrated from weekly meetings down to weekly office hours, we have seen that aside from facilitating discussions for other groups these office hours are largely unnecessary. i don't have a proposal at the moment, beyond this email, but i would appreciate any and all feedback to help us reach a place where the SIG can still react as needed to the community but also reduce its surface area. the heart of these goals is to sustain and preserve the hard work that has been done over the years, and also to recognize the diminishing availability of our membership. peace o/

[cyborg] Proposing core reviewers
by Nadathur, Sundar 12 Mar '20

12 Mar '20

Hello all, Brin Zhang has been actively contributing to Cyborg in various areas, adding new features, improving quality, reviewing patches, and generally helping others in the community. Despite the relatively short time, he has been one of the most prolific contributors, and brings an enthusiastic and active mindset. I would like to thank him and acknowledge his significant contributions by proposing him as a core reviewer for Cyborg. Shogo Saito has been active in Cyborg since Train release. He has been driving the Cyborg client improvements, including its revamp to use OpenStackSDK. Previously he was instrumental in the transition to Python 3, testing and fixing issues in the process. As he has access to real FPGA hardware, he brings a users’ perspective and also tests Cyborg with real hardware. I would like to thank and acknowledge him for his steady valuable contributions, and propose him as a core reviewer for Cyborg. Some of the currently listed core reviewers have not been participating for a lengthy period of time. It is proposed that those who have had no contributions for the past 18 months – i.e. no participation in meetings, no code contributions and no reviews – be removed from the list of core reviewers. If no objections are made known by March 20, I will make the changes proposed above. Thanks. Regards, Sundar

[neutron][largescale-sig] Debugging and tracking missing flows with l2pop
by Krzysztof Klimonda 12 Mar '20

12 Mar '20

Hi, (This is stein deployment with 14.0.2 neutron release) I’ve just spent some time debugging a missing connection between two VMs running on OS stein with ovs+l2pop enabled and the direct cause was missing flows in table 20 and a very incomplete flood flow in table 22. Restarting neutron-openvswitch-agent on that host has fixed the issue. Last time we’ve encountered missing flood flows (in another pike-based deployment), we tracked it down to https://review.opendev.org/#/c/600151/ and since then it was stable. My initial thought was that we were hitting the same bug - a couple of VMs are scheduled on the same compute, 3 ports are activated at the same time, and the flood entry is not broadcasted to other computes. However that issue was only affecting one of the computes, and it was the only one missing both MAC entries in table 20 and VXLAN tunnels in table 22. The only other idea I have is that the compute with missing flows have not received them from rabbitmq, but there I see nothing in logs that would suggest that agent was disconnected from rabbitmq. So at this point I have three questions: - what would be a good place to look next to track down those missing flows - for other operators, how stable do you find l2pop in general? and if you have problems with missing flows in your environment, do you try to monitor your deployment for that? -Chris

[nova] Breaking up and migrating the nova-live-migration job to Zuulv3
by Lee Yarwood 11 Mar '20

11 Mar '20

Hello all, I've started PoC'ing some ideas around $subject in the topic below and wanted to ask the wider team for feedback on the approach I'm taking: https://review.opendev.org/#/q/topic:nova-live-migration-zuulv3 My initial idea is to break the job up into the following smaller multinode jobs that are hopefully easier to understand and maintain. * nova-multinode-live-migration-py3 A simple LM job using the qcow2 imagebackend and LVM/iSCSI c-vol. * nova-multinode-live-migration-ceph-py3 A ceph based LM job using rbd for both imagebackend and c-vol. * nova-multinode-evacuate-py3 A separate evacuation job using qcow2 imagebackend and LVM/iSCSI c-vol. The existing script *could* then be ported to an Ansible role as part of the migration to Zuulv3. Hopefully this is pretty straight forward but I'd appreciate any feedback on this all the same. Cheers, -- Lee Yarwood A5D1 9385 88CB 7E5F BE64 6618 BCA6 6E33 F672 2D76

[neutron] Why network performance is extremely bad and linearly related with number of VMs?
by Yi Yang (杨�D)-云服务集团 11 Mar '20

11 Mar '20

Hi, All Anybody has noticed network performance between VMs is extremely bad, it is basically linearly related with numbers of VMs in same compute node. In my case, if I launch one VM per compute node and run iperf3 tcp and udp, performance is good, it is about 4Gbps and 1.7Gbps, for 16 bytes small UDP packets, it can reach 180000 pps (packets per second), but if I launch two VMs per compute node (note: they are in the same subnet) and only run pps test case, that will be decrease to about 90000 pps, if I launch 3 VMs per compute node, that will be about 50000 pps, I tried to find out the root cause, other VMs in this subnet (they are in the same compute node as iperf3 client) can receive all the packets iperf3 client VM sent out although destination MAC isn’t broadcast MAC or multicast MAC, actually it is MAC of iperf3 server VM in another compute node, by further check, I did find qemu instances of these VMs have higher CPU utilization and corresponding vhost kernel threads also also higher CPU utilization, to be importantly, I did find ovs was broadcasting these packets because all the ovs bridges didn’t learn this destination MAC. I tried this in Queens and Rocky, the same issue is there. By the way, we’re using linux bridge for security group, so VM tap interface is attached into linux bridge which is connected to br-int by veth pair. Here is output of “ovs-appctl dpif/dump-flows br-int” after I launched many VMs: recirc_id(0),in_port(12),eth(src=fa:16:3e:49:26:51,dst=fa:16:3e:a7:0a:3a),et h_type(0x0800),ipv4(tos=0/0x3,frag=no), packets:11012944, bytes:726983412, used:0.000s, flags:SP., actions:push_vlan(vid=1,pcp=0),2,set(tunnel(tun_id=0x49,src=10.3.2.17,dst=10 .3.2.16,ttl=64,tp_dst=4789,flags(df|key))),pop_vlan,9,8,11,13,14,15,16,17,18 ,19 $ sudo ovs-appctl fdb/show br-floating | grep fa:16:3e:49:26:51 $ sudo ovs-appctl fdb/show br-tun | grep fa:16:3e:49:26:51 $ sudo ovs-appctl fdb/show br-bond1 | grep fa:16:3e:49:26:51 $ sudo ovs-appctl fdb/show br-int | grep fa:16:3e:49:26:51 All the bridges can’t learn this MAC. My question is why ovs bridges can’t learn MACs of other compute nodes, is this common issue of all the Openstack versions? Is there any known existing way to fix it? Look forward to hearing your insights and solutions, thank you in advance and have a good day.

[manila] share group replication spike/questions
by Dong.Ding＠dell.com 11 Mar '20

11 Mar '20

Hi, guys, As we talked about the topic in a virtual PTG few months ago. https://etherpad.openstack.org/p/shanghai-ptg-manila-virtual (Support promoting several shares in group (DELL EMC: dingdong) I'm trying to write a manila-spec for it. It's my first experience to implement such feature in framework. I need to double check with you something, and hope you can give me some guides like: 1. Where is the extra-spec defined for group/group type, it's in Manila repo, right? (like manila.db.sqlalchemy.models....) 2. The command cli should be implemented for 'python-manilaclinet' repo, right? (I have never touched this repo before) 3. Where is the rest-api should be implemented? 4. And more tips you have? like any other related project should be changed? Just list what I know, and more details questions will be raised when implementing, I think. FYI Thanks, Ding Dong

One of Horizon's requirements is pyscss package. Which had last release over 4 years ago... Two days ago setuptools v46 got released. One of changes was drop of Features feature. Today Kolla builds started to fail: INFO:kolla.common.utils.horizon:Collecting pyScss===1.3.4 INFO:kolla.common.utils.horizon: Downloading http://mirror.ord.rax.opendev.org:8080/pypifiles/packages/1d/4a/221ae7561c8… (120 kB) INFO:kolla.common.utils.horizon:[91m ERROR: Command errored out with exit status 1: INFO:kolla.common.utils.horizon: command: /var/lib/kolla/venv/bin/python -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-rr0db3qs/pyScss/setup.py'"'"'; __file__='"'"'/tmp/pip-install-rr0db3qs/pyScss/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base /tmp/pip-install-rr0db3qs/pyScss/pip-egg-info INFO:kolla.common.utils.horizon: cwd: /tmp/pip-install-rr0db3qs/pyScss/ INFO:kolla.common.utils.horizon: Complete output (5 lines): INFO:kolla.common.utils.horizon: Traceback (most recent call last): INFO:kolla.common.utils.horizon: File "<string>", line 1, in <module> INFO:kolla.common.utils.horizon: File "/tmp/pip-install-rr0db3qs/pyScss/setup.py", line 9, in <module> INFO:kolla.common.utils.horizon: from setuptools import setup, Extension, Feature INFO:kolla.common.utils.horizon: ImportError: cannot import name 'Feature' Are there any plans to fix it? pyscss project got issue: https://github.com/Kronuz/pyScss/issues/385 In Kolla I made ugly workaround: https://paste.centos.org/view/2e29d284 What are plans of Horizon team?
