[swift] Ideas: Object Locking
by David Zanetti 09 Sep '24

09 Sep '24

Hello everyone! We've added an entry to the Swift ideas page about implementing Object Locks. The full description of what this would be and how we expect it to work is in the ideas page here: https://wiki.openstack.org/wiki/Swift/ideas/object-lock I have two questions of the community. The first is whether work on this would be accepted by the Swift project, as we wouldn't want to expend efforts on something we'd have to carry as our own patches to upstream. The second is if there is any interest from other people to collaborate on design/implementation of the locking feature. Happy to take replies off-list if people prefer, and thanks for reading this far! (Ob-reply: Yes, we know Ceph RGW does this already. We use Swift for Object for $REASONS, which we'd like to keep doing.) -- David Zanetti Chief Technology Officer [1]Aotearoa New Zealand's cloud provider e david.zanetti(a)catalystcloud.nz w catalystcloud.nz Follow us on LinkedIn [2] Level 9, 33 Federal Street, Auckland 1010 [1] https://catalystcloud.nz/ [2] Follow us on LinkedIn https://www.linkedin.com/company/catalyst-cloud-limited/

[all][tc][ptls] Eventlet: Python 3.13 - Attach your seatbelt
by Herve Beraud 06 Sep '24

06 Sep '24

Hi all, As Python 3.13 is close to become a reality, new concerning incompatibilities between this new CPython version and Eventlet also become a reality: - https://github.com/eventlet/eventlet/issues/964 Fedora Python maintainers proposed a patch, but for now the problem remains unsolved. Also, many people reported bugs related to incompatibility between python3.12/dnspython/eventlet/pip-system-cert. There is an example who summarize well the problem https://github.com/eventlet/eventlet/issues/957 Do you have some visibility concerning the adoption of Python 3.13 into Openstack? Turbulences ahead... -- Hervé Beraud Senior Software Engineer at Red Hat irc: hberaud https://github.com/4383/

[charms] Proposing Brian Haley and Nicolas Bock for OpenStack Charms core
by Edward Hope-Morley 05 Sep '24

05 Sep '24

Hi everyone, I would like to propose Brian Haley and Nicolas Bock for the OpenStack Charms core development team. Both Brian and Nicolas have been members of the stable charms core team since 2023 and been hugely helpful in that role, providing insightful feedback to reviews as well as contributions of their own. Nicolas has also been a contributor to the OpenStack charms for many years and Brian is well versed in the ways of upstream OpenStack maintenance through his role as Neutron PTL so I have full confidence that they will prove valuable additions to the charms-core team. Thank you both for your contributions to the project! Regards, Ed

[Kolla] [LetsEncrypt] Internal/External/Backend Certificates
by jjjamesg＠proton.me 05 Sep '24

05 Sep '24

Hi all, another one here that can't seem to get kolla running with letsencrypt certs, just curious as to what settings are required for kolla to pull internal/external/backend certs from letsencrypt? I've looked at the docs and have tried a few settings but keep getting errors, sure i had this working last week before i tore it down ready to deploy for production and now i just cant get it to complete the deployment because of certs, only thing i can think of is i need to run kolla-ansible -i multinode certificates but i thought that was just for self made certs? Also, what are best practices for backend tls certs, self signed or using the internal cert etc?? Is it possible to use letsencrypt at all for backend? Cheers all

[cinder] Offering local storage using the device mapper clone target
by Jan Horstmann 04 Sep '24

04 Sep '24

Hello cinder team and other interested parties, I have recently started thinking about ways to offer local storage as part of the OpenStack block storage service. Naturally any solution would require to transparently migrate volumes to and with the instances they are attached to, so that the user experience of being able to access their storage from anywhere would not be degraded. Fortunately, with the device mapper clone target ([1]), a mechanism is available in the linux kernel which allows to do exactly that: Create copies of devices (even network attached ones) while allowing to immediately use the target device. I have detailed the motivation and some implications of having local storage in the block storage service in a blog post [2], which I do not want to repeat here in order to not make this mail longer than it needs to be. The blog post also outlines a way to implement a cinder driver leveraging this mechanism, which is loosely based on the way cinder migrates volumes between backends, i.e.: When a volume is going to be attached, a new volume is created on the instance's host, which is backed by a device mapper clone target with the original volume as its source; Then the volume objects are switched and a local connector is returned, which may be used immediately. Since then I went ahead and created a proof of concept cinder driver ([3]), which roughly follows what is outlined in the post (some lessons were already learned during implementation). The driver is based on the in-tree lvm driver for basic volume management and can do basic things like create/delete, attach/detach and also handles live migration and rebuilding of instances. There is nothing currently regarding snapshots and volume migrations will definitly not work as expected yet, but it should be sufficient to get a feeling for the general idea. I am currently looking for feedback on the idea and the implementation and would like to know if this is of interest to others. I am happpy to answer any questions or present this in more detail. In case anyone wants to take the driver for a spin I am going to leave some instructions on how to set up the environment in [4]. Regards, Jan [1] https://docs.kernel.org/admin-guide/device-mapper/dm-clone.html [2] https://scs.community/2024/07/12/local-block-storage-via-dm-clone/ [3] https://github.com/janhorstmann/openstack-cinder/tree/59e1808a24d112d2e8d08… [4] - Set up an OpenStack environment - Create an lvm2 volume group and run a cinder volume service on every hypervisor - Configure a new backend on every volume service with the same `volume_backend_name` Configure it like you would an lvm backend, but with `volume_driver = cinder.volume.drivers.dmclone.DMCloneVolumeDriver`, e.g.: [local-volumes] volume_driver = cinder.volume.drivers.dmclone.DMCloneVolumeDriver volume_group = local volume_backend_name = local-volumes target_helper = tgtadm target_protocol = iscsi lvm_type = default I have tested with the values above, but any target driver should work -- Jan Horstmann Senior Cloud Engineer Mail: horstmann(a)osism.tech Web: https://osism.tech OSISM GmbH Talweg 8 / 75417 Mühlacker / Deutschland Geschäftsführer: Christian Berendt Unternehmenssitz: Mühlacker Amtsgericht Mannheim, HRB 750852

[all][rbac][tacker][horizon][neutron][octavia] oslo.policy 4.4.0 enable the RBAC new defaults by default
by Ghanshyam Mann 03 Sep '24

03 Sep '24

Hi All, You might have seen some fixes and testing changes on your project to test the oslo.policy 4.4.0. oslo.policy 4.4.0 enables the RBAC new defaults by default, which means those will be enabled for all the OpenStack services unless they have disabled them by overriding the default value. It enables both enforce_scope as well enforce_new_defaults. The requirement change[1] adds the oslo.policy 4.4.0 in upper-constraints which will enable the latest oslo.policy in upstream CI. Along with jobs failing on requirement change, I tested more integration jobs and fixing the failures[2]. Most of the fixes have been merged, and a few of them are up for review. Below is the list of fixes up for review, please merge them before the requirement change is merged. If there is something else I missed to test and failed, let me know on IRC or here. In-progress fixes: - Horizon: - https://review.opendev.org/c/openstack/horizon/+/927571 - Tacker: - https://review.opendev.org/c/openstack/tacker/+/926089/5 - Neutron + Designates job (making it non-voting until we figure out the root cause): - https://review.opendev.org/c/openstack/neutron-tempest-plugin/+/927648 - Octavia (Michael is working on more modifications on this ): - https://review.opendev.org/c/openstack/octavia-tempest-plugin/+/926867 [1] https://review.opendev.org/c/openstack/requirements/+/925464 [2] https://review.opendev.org/q/topic:%22secure-rbac%22+owner:gmann@ghanshyamm… -gmann

Can not work on Dashboard(throwing 504-Timed out) on Openestack-on-ansible environment
by sudeb ghosh 02 Sep '24

02 Sep '24

Hi Team , We have an 'Openstack on Ansible' Private cloud environment with 3 controllers & 35 Compute host nodes. Age of this environment is around 4 yrs. DISTRIB_RELEASE: 21.2.1 DISTRIB_CODENAME: Ussuri DISTRIB_DESCRIPTION: Openstack-Ansible Top of this Linux containers are there where the services are running inside such as neutron, galera, horizon, keystone, etcd, nova-api, utility etc for all 3 controllers. Current Set Up: We find in haproxy config file only controller2 & controller3 are configured. So the galera container along with Mariadb Services are running fine within controller2(Primary) & controller3. But Galera container in controller1 is stopped & mariadb service not running here. Issue Started with: All of suddent we faced, user not able to log in dashboard 5 days back. The dashboard page is not getting loaded. Action Taken: We find Maria-DB in controller2 is non-primary & DB on controller-3 is down. Made Maria-DB in controller2 primary & DB on controller-3 up which resulted to load the page & log in. Current Issue: 1) But the Dashboard page is too slow to work. Sometime throwing 504-Timed out error 2) VM Console(VNC) not working for any VM 3) NOt able to create any VM(Showing 'Scheduling' continuously) 4) 25/35 Hypervisons are showing down in Dashboard within 'Hypervisor list' tab but those are up as per CLI 5) Not able to create any volume Request you to go through the Problem description & Can anybody help me out providing the solution for the same? Pl do intimate me if any more info is required. Regards, Sudeb Ghosh sudeb_ece(a)yahoo.co.in BR// Sudeb Ghosh 7044064878 9332034788

[nova][ci] openstack-tox-docs job failing, hold your rechecks
by melanie witt 01 Sep '24

Hey all, Just a heads up... The last several openstack-tox-docs job runs on the master branch have failed, both gate and check queues: https://zuul.opendev.org/t/openstack/builds?job_name=openstack-tox-docs&pro… because of AFAICT the following warning which is treated as an error: 2024-08-28 19:24:04.604443 | ubuntu-jammy | /home/zuul/src/opendev.org/openstack/nova/.tox/docs/lib/python3.10/site-packages/openstackdocstheme/page_context.py:70: RemovedInSphinx90Warning: Sphinx 9 will drop support for representing paths as strings. Use "pathlib.Path" or "os.fspath" instead. 2024-08-28 19:24:04.649996 | ubuntu-jammy | src_file = full_src_file[len(str(app.builder.env.srcdir)):].lstrip('/') The error looks like it's coming from Sphinx and I did find an upper-constraints bump of Sphinx happened earlier today: https://review.opendev.org/c/openstack/requirements/+/927358 The version was bumped from 7.4.6 to 8.0.2 -- which may possibly be related to the failures. I will look more into the failure but if anyone else knows how to fix this, please feel free to propose something. -melwitt
