numa filtering
by Gk Gk 12 Jul '24

12 Jul '24

How does the scheduler check the numa nodes availability in the background ? Does it use any db like placement to calculate the allocation, resource etc for numa ? I need just the logic in the scheduler for this check ? Thanks Y.G

[nova] Instance stuck in hard reboot
by Francesco Di Nucci 11 Jul '24

11 Jul '24

Hi all, I hard rebooted an instance while a compute node was down, and now on the dashboard/CLI it is stuck in hard rebooting status. I am able to start/stop/reset it through virsh on the compute node, but I can't get it out of this loop in OpenStack, any suggestions? Thanks in advance -- Francesco Di Nucci System Administrator Compute & Networking Service, INFN Naples Email: francesco.dinucci(a)na.infn.it

[Swift - proxy server] manually exclude nodes via new middleware
by Olivier Chaze 11 Jul '24

11 Jul '24

Hi all, I am writing to introduce a new middleware component, ExcludeNode, which we've just started to develop to enhance node management within the Swift proxy server. [Middleware Overview] ExcludeNode is designed to dynamically exclude specific nodes from the proxy's operations. This middleware reads a list of nodes to be excluded from a specified file and prevents these nodes from being considered during normal operations. Main reason for developing this middleware is to avoid objects request latency/failure when nodes are down or when rebalancing objects after adding new nodes for example. The main functionalities include: - Node Exclusion Check: Validates if a node (IP:PORT) is listed in the exclusion file. - Dynamic Updates: Allows updating the exclusion list by writing node information to the specified file (IP:PORT). - Clear the exclusion list How to use it ? Assuming 1.2.3.4 storage node is down, requests will fail with : proxy-server: ERROR with Object server 1.2.3.4:6210/sdm re: Trying to GET /v1/AUTH_[...]: ConnectionTimeout (2.0s) (txn: tx19b7067dcb0c442e96a10-0066867068) To ban the disk 1.2.3.4:6210/sdm , on each proxy-server : curl -X POST `hostname`:8080/exclude_node -H "Content-Type: application/json" -d {"ip":"'1.2.3.4","port":6210}"' in proxy-server.log will be logged : proxy-server: Node added to exclusion list: 1.2.3.4:6210 (txn: tx0f292e3b08f940b5be3d9-0066867068) This way, the node won't serve any request and depending the request type, this latter will be redirected to another primary or handoff node. It will remain like this until the disk is manually removed from the exclusion list and every time this node would have been chosen to serve a request you'll get a log : proxy-server: Node 1.2.3.4:6210 (sdm) explicitly excluded by exclude_node middleware. (txn: txeb9f5953ee3343dbb9699-006686707a) I would greatly appreciate the community's feedback on the following: * FUNCTIONALITY: Does the middleware fulfill a common need? * IMPLEMENTATION: Are there any concerns regarding the code implementation or its impact on existing functionalities? We'd like to submmit this middleware upstream but to be efficient and avoid wasting everybody's time I'd like some feedbacks first :) The code itself is quite simple today but we plan to add features like auto excluding a node reported as unmounted by swift-recon for example. exclude_node.py middleware : https://kpaste.infomaniak.com/nRp8AdJGnMuLCoP7czIbL9IBJjlSkyYS#ARXTJo5ZnGa5… server.py modification : https://kpaste.infomaniak.com/Qvy992wlRbc6yEgrIPhAhyrh2V3-Gipy#E2TaKDAXQdXp… proxy-server.conf : [pipeline:main] - pipeline = [...] proxy-server + pipeline = [...] exclude_node proxy-server [filter:exclude_node] use=egg:swift#exclude_node exclude_nodes_filename = /dev/shm/excluded_nodes Thank you in advance for your feedback, Olivier

Cannot create windows image on Openstack
by Ramzi Abdallah 11 Jul '24

11 Jul '24

I have installed openstack version bobcat on Centos 9 Stream. The installation went fine and I am able to login and launch the cirros image. The problem I am facing is with windows images. When I try to upload the Windows Server 2012 R2 Standard Evaluation for OpenStack which I downloaded from cloudebase I get this error: TypeError: Cannot read properties of undefined (reading 'data') - Error: Unable to create the image. At first I though the problem is from the image so I created my own with all the needed drivers and got the same problem. Appreciate any help is someone experienced this before Ramzi

[python-openstackclient] openstack client can't use swift command
by chunyang wu 10 Jul '24

10 Jul '24

Hello team: The latest version of python-openstackclient on pypi.org is 6.0.0[0], but this version lacks the ability to use commands related to the Swift project due to the absence of the simplejson package. Although this issue was addressed in a recent commit [1]. The fix has not yet been released on pypi.org. I kindly request that the team release a new version to address this issue as soon as possible. thanks [0]: https://pypi.org/project/python-openstackclient/6.6.0/#history [1]: https://review.opendev.org/c/openstack/python-openstackclient/+/920001

Magnum Caracal: magnum-conductor fails with after sql QueuePool limit exhaustion
by Michel Jouvin 10 Jul '24

10 Jul '24

Hi, In our tests of Magnum Caracal, we are experiencing a bad error in openstack-magnum-conductor causing it not to work until it is restarted. The problem is caused by a high number of connections to the magnum DB (compared to what can be seen in Antelope version), exceeding the QueuePool limit configured with max_pool_size (+ an overflow of 50). This is described with more details at https://bugs.launchpad.net/magnum/+bug/2067345 that remained mostly unanswered (but with several people joining to say they were experiencing the same issue). Are they people running Magnum Caracal on this list? Are you experiencing the same issue? In our case we are using RDO distribution (EL9-based) and the Magnum DB is on a remote server. Any suggestion welcome! Best regards, Michel

[adjutant][tc] Checking in on project health
by Goutham Pacha Ravi 10 Jul '24

10 Jul '24

Hello, During a Technical Committee meeting [1], we were made aware that adjutant's CI jobs are perma-failing; and trivial bot-created patches as well as patches from folks addressing CI issues [2] haven't received any review feedback. I wanted to check on the status of development of this project and its deliverables (adjutant, python-adjutantclient, adjutant-ui). If these are not actively developed, perhaps it is time to retire them [3]. Let me know what you think.

Network demand for controller nodes
by William Muriithi 10 Jul '24

10 Jul '24

Hello, Does anyone know if controller nodes are demanding on network needs? I have a situation where I don't have enough 10GB/s port in the switch. Would a cluster be network constrained if I have three controllers using 1GB/s connections and the execution and storage nodes are on 10GB/s connections? Does the VM traffic ever transverse the controller's network cards? In another word, is there a valid requirement for 10GB/s on openstack controllers? Regards, William

[skyline][tc] Graduating skyline out of the "Emerging Projects" list
by Goutham Pacha Ravi 10 Jul '24

10 Jul '24

Hi, We were discussing in a recent TC meeting that Skyline seems to be ready to lose the "Emerging project" tag [1]. The arguments supporting it's graduation are: - The project is actively maintained, and has had consistent releases since the Zed release [2][3][4][5] - The project is being used in production cloud deployments [6] - Operators have requested skyline's inclusion in deployment and configuration management projects [7][8] Wu Wenxiang / Skyline team - is this assessment correct? If yes, are there any objections to removing Skyline from [1]? If it helps, the project team can re-assess the OpenStack project requirements we have [9] and work on any deficiencies.

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2024.2/R-12)
by Goutham Pacha Ravi 09 Jul '24

09 Jul '24

Hello Stackers, Time flies, we're over halfway through our 2024.2 (Dalmatian) release cycle! This second half is usually chock-full of release deadlines, specification and code freezes, and more release action [1]. The past week was a short work week for many folks in the Technical Committee due to local holidays, so this update will be brief. Hervé Beraud (hberaud) and Mike Bayer (zzzeek) joined us at the TC's video meeting last week, and they took us through the goal proposal to remove eventlet from OpenStack [2][3][4][5][6]. The meeting was well attended, and it involved a walkthrough of SQLAlchemy, where zzzeek presented how it supports asyncio and a library that allows non-async definitions to invoke awaitables inside an asyncio application. We didn't merge any new governance proposals this week, but several are in review as noted below. === Weekly Meeting === The weekly meeting was held simultaneously on video and IRC. Please check out the recording posted to the TC's YouTube channel [7] as well as the meeting log on eavesdrop [8]. We have new governance proposals that concern Freezer and Monasca, the two projects that were marked "inactive" during the last release cycle. We discussed providing the Skyline team instructions and time to graduate from being an "emerging" project. The TC reiterated its commitment to ensure that all decisions are made asynchronously and recorded on Gerrit to involve community members in different time zones. The rest of the meeting was focused on the eventlet removal discussion. It was a very informative presentation that I'd recommend all OpenStack maintainers review. We took a note to time-box the reviews on the goal proposal. I'd like to request reviews and any strong objections to be expressed on the proposal as soon as possible. The next Technical Committee meeting is today, 2024-07-09 at 1800 UTC! The meeting will be hosted on OFTC's #openstack-tc channel, and the agenda has been posted to the Meetings Wiki Page [9]. Please consider joining us! === Governance Proposals === Remove Eventlet From Openstack | https://review.opendev.org/c/openstack/governance/+/902585 Update criteria for the inactive projects to become active again | https://review.opendev.org/c/openstack/governance/+/921500 Remove Monasca from inactive list | https://review.opendev.org/c/openstack/governance/+/923466 Transition Watcher project to DPL | https://review.opendev.org/c/openstack/governance/+/923583 Inactive state extensions: Freezer | https://review.opendev.org/c/openstack/governance/+/923441 Retire Kuryr-Kubernetes and Kuryr-Tempest-Plugin | https://review.opendev.org/c/openstack/governance/+/922507 Update to include docs and miscellaneous repos for AC status | https://review.opendev.org/c/openstack/governance/+/915021 Adding a rule to manage the affiliation diversity requirement in the TC | https://review.opendev.org/c/openstack/governance/+/922512 === Upcoming Events === 2024-08-14: Nominations open for 2025.1 OpenStack PTL+TC elections 2024-08-29: Dalmatian-3 milestone Thank you very much for reading!

[ironic] Docs audit complete; results available
by Jay Faulkner 09 Jul '24

09 Jul '24

Hi all, Two PTGs ago, Ironic contributors had a topic about documentation -- we acknowledged our documentation was at times comprehensive, but at times incomprehensible :). This led us to enlist a professional technical writer, Dave Welsch, to assist. Dave has been working over the last few months to get feedback from Ironic users and contributors, as well as auditing our documentation and has put his final findings here: https://docs.google.com/document/d/1e9URuPHKNTx5QXdkCFAzsS0EAAxPJ-xQC4BEpDw… . Actionable bugs were a desired outcome of this, which was achieved. We filed several bugs against Ironic, tagged "docs-audit-2024" -- you can see the list here: https://bugs.launchpad.net/ironic/+bugs?field.tag=docs-audit-2024. I know that identifying issues is only part of the work needed; but it's our hope that by breaking this down and creating a path towards better docs, we'll be able to make it a less daunting task for contributors -- possibly even doable by folks from an outreachy-like program. Thanks for those who participated in this process. Feel free to reach out here if you have any questions, or to me privately. Thanks, Jay Faulkner

[Neutron] Is there a way to work around "External network not reachable from subnet" by setting a static route?
by Florian Haas 09 Jul '24

09 Jul '24

Hi everyone, here's a question I've been chewing on for some time. Please bear with me while I illustrate the background. 1. Suppose you have a regular (internal) Neutron network, subnet, and router. You now plug the subnet into the router and set an external gateway. You then create a port on the subnet. You associate a floating IP with that port. All is well. 2. Suppose instead you do plug the subnet into the router, but you don't set an external gateway on it. You try to associate a floating IP with that port. This creates a BadRequest because: "External network <uuid> is not reachable from subnet <uuid>". 3. Suppose instead you do set an external gateway on the router, but you don't connect the subnet to it. Again, you try to associate a floating IP with that port. This also creates a BadRequest because: "External network <uuid> is not reachable from subnet <uuid>". So far, so good. Up to this point, everything is behaving according to intuitive expectations. Now suppose we have * the external network, * an "outer" internal network, * a Neutron router connecting the two (that is, the router has the external network as its gateway, and has an interface to the "outer" subnet), * an "inner" internal network, * a Nova server (let's call that the "gateway"), which connects the "inner" and "outer" networks, a * another Nova server (the "worker") that sits on the "inner" network. (Suppose, for the sake of discussion, that the "gateway" runs some kind of web application firewall or other virtual security appliance, and the "worker" is a general-purpose Linux instance.) Now I can give the Neutron router a static route so that traffic to the "inner" network uses the "gateway" as its nexthop. Provided the "gateway" does its forwarding correctly, this means that the "worker" has internet connectivity via the "gateway" (which, in turn, achieves this via the router). This, too, works fine for outbound connections originating with the "worker". If I now want to assign a floating IP to the "worker", then routing-wise there really should be no problem: the router should take care of SNAT/DNAT, it would translate the floating IP into a private IP on the "inner" network, would consult its routing table, and throw packets for that "inner" network to the "gateway" to handle, per the static route that's been set. But when I try to associate a floating IP to the "worker" in this scenario, I *still* get the "External network not reachable from subnet" error, because the associated internal check[1] does not take the existing static route into account. This appears to have been an issue in other contexts as well: the defunct Tricircle project appears to have worked around this limitation via a service plugin that just omitted that check.[2] Now my questions are these: 1. Shouldn't this be fixed in core, instead? It would seem to me like the default check is too simplistic, but I might be missing something. 2. Is there a way to make this check take static routes into account, other than providing a service plugin like Tricircle used to do? Thanks!

Hi all, Is there a tool available in openstack, using which, as admin, we can list the operations executed by users like, vm operations , network related etc given their tenant uuid ? Do you think it is a good idea to have such a tool ? Thanks Y.G

when deleting an instance, its volume is not deleted
by kjme001＠gmail.com 08 Jul '24

I have the following problem, when deleting an instance, its volume is not deleted along with it, the volume remains and I then have to execute the command to detach the volume from the non-existent instance and then delete it. I don't know what could be causing this, the volume should probably be deleted together with the instance being deleted Thank you for your help

attach both virtio-scsi and virtio-blk to an instance
by Jiatong Shen 08 Jul '24

08 Jul '24

Hello, I am searching whether it is possible to use both virtio-scsi and virtio-blk at the same time for one instance. I knew it was possible to use each of them separately. I have this requirement because virtio-blk is not possible to support as many as devices like virtio-scsi, but we still want to keep virtio-blk for performance reasons and for legacy instances. Thank you for help. -- Best Regards, Jiatong Shen
