[nova][release][tooz] Hold your rechecks
by Sylvain Bauza 10 Jan '24

10 Jan '24

Hey folks, FWIW, our grenade check on SLURP upgrades is 100% failing now [1] due to a behavioural change in the tooz library [2] that's pulled by Cinder and which was released [3] and delivered to upper-contraints yesterday [4] There are different possibilities in order to unblock the gate, but until one of them is agreed and merged, please avoid wasting our CI resources by asking to recheck for something which will fail. Thanks, -Sylvain (who will send an email once the job is back up) [1] https://zuul.opendev.org/t/openstack/builds?job_name=grenade-skip-level-alw… [2] https://review.opendev.org/c/openstack/tooz/+/891355 [3] https://review.opendev.org/c/openstack/releases/+/899966 [4] https://review.opendev.org/c/openstack/requirements/+/901131

[designate] Proposal to deprecate the agent framework and agent based backends
by Michael Johnson 09 Jan '24

09 Jan '24

TLDR: The Designate team would like to deprecate the backend agent framework and the agent based backends due to lack of development and design issues with the current implementation. The following backends would be deprecated: Bind9 (Agent), Denominator, Microsoft DNS (Agent), Djbdns (Agent), Gdnsd (Agent), and Knot2 (Agent). Designate includes many backend DNS server drivers[1], many of which are "native" (also known as xfr type backends) backend implementations. In addition to the "native" backends, Designate has an agent backend[2] that supports other backends via an agent process. To quote the agent backend documentation[2]: This backend uses an extension[3] of the DNS protocol itself to send management requests to the remote agent processes, where the requests will be actioned. The rpc traffic between designate and the agent is both unauthenticated and unencrypted. Do not run this traffic over unsecured networks. Here are the reasons we are proposing to deprecate the agent framework now: 1. The agent protocol used by Designate is using an "unassigned"[4][5] DNS opcode (14) that is causing problems with the dnspython library >= 2.3.0 which is now validating the opcode when building DNS messages. It is a bad practice to use "unassigned" values as they may be officially assigned at any time, likely with an incompatible message format. 2. The agent backends are not tested in the OpenStack jobs[1]. 3. Many of the agent backends have been marked as "Experimental" since 2016 with no additional contributions beyond general repository code maintenance. 4. The protocol between the Designate worker process and the agent process is unauthenticated and unencrypted. 5. We do not know of a development resource to rewrite the agent framework protocol to address issue #1 and #4 above. 6. The introduction of catalog zones[6] may eliminate the need for some of the agent based backend drivers. By marking the agent framework and agent based backends "deprecated" in the Antelope cycle, we would remove the code no earlier than the "C" release of OpenStack (per the OpenStack deprecation policy[7]). In the meantime, issue #1 has been worked around by overriding the dnspython opcode validation[7] as needed in the Designate code (similar to a monkey patch). This is not a sustainable long term solution. The following backend agent based drivers would be marked "deprecated" in addition to the agent framework itself: Bind9 (Agent) Denominator Microsoft DNS (Agent) Djbdns (Agent) Gdnsd (Agent) Knot2 (Agent) We plan to propose patches for the deprecation over the next week, but will not merge them until at least January 24th to allow time for comment from the community. If you have concerns about this deprecation plan or are interested in rewriting the agent framework protocol to address the above issues, please reply to this announcement.

[octavia][neutron] ask about LB with DVR
by Nguyễn Hữu Khôi 09 Jan '24

09 Jan '24

Hello guys. I see that more and more people use Octavia but it depends on network nodes which cause bottlenecks or single point of failure . I would like to know if we have some plan to make Octavia works without network nodes. Thank you. Nguyen Huu Khoi

LVM Cinder
by Jorge Visentini 08 Jan '24

08 Jan '24

Hi all! My scenario: We currently use oVirt and are studying the possibility of migrating to OpenStack in the future. Today we use Storages Enterprise 3PAR and Dell PowerVault. I've even tried to integrate 3PAR, but it's too complex for me for now... Stupid question... If I work directly with LVM, that is, deliver a LUN to all my hosts, create an LVM and deliver it to Cinter, will I have the Live Migration, HA instances, snapshot and other features ? Cheers! -- Att, Jorge Visentini +55 55 98432-9868

Issue when connecting to openstack object storage with openstacksdk
by sadir＠free.fr 05 Jan '24

05 Jan '24

Hello, I am currently developing a software application to access the OpenStack object store service on an IBM Spectrum Scale server. I first created a Python application which is manipulating objects and containers thru the OpenStack's object storage REST API (https://docs.openstack.org/api-ref/object-store) It works fine and I had no issue to access the server object store service by this way. But I also need to access the OpenStack object store service thru the openstacksdk (https://docs.openstack.org/openstacksdk/latest) Unfortunately, the connection does not seem to work properly in this case, even when using the same identifiers than in the working Python/REST application. The connection stalls and goes into some sort of timeout. I also made some tests by putting wrong identifiers, and then it fails immediately with a different error message. It makes me think that something goes wrong after the authentication process. The error message I have is this one: Failed to contact the endpoint at http://yeti.ds.eurecom.fr:8080/v1/AUTH_da0d8589692741d1b2a82956568227e6 for discovery. Fallback to using that endpoint as the base url. I am wondering if there is some additional configuration to perform on the server or the network to make it work as expected. Could you please provide me with some support so that I can sort out what's going on? I could of course share the Python piece of code I am using for my testing. Thank you for your help.

[TC][Monasca] Proposal to mark Monasca as an inactive project
by Sławek Kapłoński 05 Jan '24

05 Jan '24

Hi, I just proposed patch [1] to mark Monasca as inactive project. It was discussed during last TC meeting on 03.10.2023. Reasons for that are described in the commit message of the [1] but I will also put all of it here: previous cycle there wasn't almost any contributions to that project and most active contributors in last 180 days were Elod Illes and Dr. Jens Harbott who were fixing some Zuul configuration issues only. Here are detailed statistics about Monasca projects: Validating Gerrit... * There are 7 ready for review patches generated within 180 days * There are 2 not reviewed patches generated within 180 days * There are 5 merged patches generated within 180 days * Unreviewed patch rate for patches generated within 180 days is 28.0 % * Merged patch rate for patches generated within 180 days is 71.0 % * Here's top 10 owner for patches generated within 180 days (Name/Account_ID: Percentage): - Dr. Jens Harbott : 42.86% - Joel Capitao : 28.57% - Elod Illes : 28.57% Validate Zuul... Set buildsets fetch size to 500 * Repo: openstack/monasca-log-api gate job builds success rate: 82% * Repo: openstack/monasca-statsd gate job builds success rate: 95% * Repo: openstack/monasca-tempest-plugin gate job builds success rate: 81% * Repo: openstack/monasca-common gate job builds success rate: 84% * Repo: openstack/monasca-kibana-plugin gate job builds success rate: 83% * Repo: openstack/monasca-ceilometer gate job builds success rate: 100% * Repo: openstack/monasca-events-api gate job builds success rate: 83% * Repo: openstack/monasca-ui gate job builds success rate: 88% * Repo: openstack/monasca-specs gate job builds success rate: 100% * Repo: openstack/monasca-grafana-datasource gate job builds success rate: 100% * Repo: openstack/monasca-persister gate job builds success rate: 98% * Repo: openstack/monasca-notification gate job builds success rate: 93% * Repo: openstack/monasca-thresh gate job builds success rate: 100% * Repo: openstack/monasca-api gate job builds success rate: 76% * Repo: openstack/monasca-agent gate job builds success rate: 98% * Repo: openstack/python-monascaclient gate job builds success rate: 100% * Repo: openstack/monasca-transform gate job builds success rate: 100% What's next? According to the "Emerging and inactive projects" document [2] if there will be no volunteers who will step up and want to maintain this project before Milestone-2 of the 2024.1 cycle (week of Jan 08 2024) there will be no new release of Monasca in the 2024.1 cycle and TC will discuss if project should be retired. So if You are interested in keeping Monasca alive and active, please reach out to the TC to discuss that ASAP. Thx in advance.

[magnum] magnum-capi management cluster controle plane in HA
by Satish Patel 04 Jan '24

04 Jan '24

Folks, In the lab I have deployed a magnum-capi driver with a single node kind cluster and it works great. Now I want to take it to production and make sure my capi management cluster runs on a HA environment of k8s and survives all kinds of failure. I have deployed 3 node k8s using kubespray and deployed CAPI applications on top of it using clusterctl init command but it default created a replica of 1/1 for all pods. How do I tell clusterctl to create a replica with 3 for HA and how does data replication work? How do I take backup/restore of data in k8s cluster using clusterctl for disaster recovery? I have checked official documents but it's a little confusing so I'm asking question here to clear my doubts. Cheers! ~S
