[designate] Support for quorum queues
by Thomas Goirand 06 Jun '25

06 Jun '25

Hi, When setting-up Designate with quorum queues, when designate-central starts, I get: Queue.declare: (406) PRECONDITION_FAILED - invalid property 'non-durable' for queue 'central' in vhost '/' Does Designate support quorum queues? If so, how com it's trying to set 'non-durable', which doesn't exist as attribute, at least with RabbitMQ 4.0.5? Cheers, Thomas Goirand (zigo)

[nova] Information Sharing for Arm CCA Feature (Following 4/8 PTG)
by taketani.ryo＠fujitsu.com 06 Jun '25

06 Jun '25

Thank you for the productive discussion about Arm CCA feature [1] at the PTG on April 8th. > The use case for Arm CCA looks ok. But it is a bit early. It is wise to wait at least libvirt / qemu release to have a "stable" code. > We may want to have a OS distribution version (such as Ubuntu XX.YY) which supports Arm CCA so that users can actually use/test the feature The above information is quoted from the PTG Etherpad [2](L316) summary. I'd like to follow up on these points. I'd like to share relevant information about Arm CCA surrounding components (libvirt, QEMU, OS Distributions(e.g., Ubuntu xx.xx), hardware) as it becomes available, and proceed with the discussion step by step.. I'm starting with this email, but if there's a more appropriate method for sharing this type of information, please let me know. Here's the Arm CCA software components information I can share at this time: * Linux Kernel: The roadmap is outlined on the fifth page of the third attachment in this link [3]. The initial commits I've proposed to OpenStack are focused on RMM 1.0. KVM host support for RMM 1.0 will be available in H2 2025. * QEMU Upstream Status: The development is in-progress, awaiting the Linux Kernel merge * libvirt Upstream Status: The development is in-progress, awaiting the QEMU merge * OS Distribution Support: The road map is not clear now > We may want to have a OS distribution version (such as Ubuntu XX.YY) which supports Arm CCA so that users can actually use/test the feature I have a question regarding the above. For design discussions leading to spec approval, I understand that upstream QEMU/libvirt stable release is necessary. Is a specific OS distribution release (e.g., Ubuntu xx.xx) also required for spec approval?

[neutron] Approach to a spec for OVN BGP integration (RFE 2111276)
by Frode Nordahl 04 Jun '25

04 Jun '25

Hello, Jakub, Thank you for filing the RFE for Neutron support for OVN native support for route exchange, which includes BGP. We appear to have a common goal of making use of this with OpenStack, and we have time set aside this cycle to work towards this goal. Communication through IRC and e-mail often has limited bandwidth, and I wonder if you would be interested in participating in a A/V sync on some cadence to get us off the ground with the initial spec work. We have good experience with how the core OVN A/V sync is organized and we could do something similar for this. WDYT? -- Frode Nordahl

[cinder]How do I configure Cinder to recognize free space in the data pool when using a Ceph Erasure Coded Pool?
by Yuta Kambe (Fujitsu) 04 Jun '25

04 Jun '25

Hi everyone, I'm using a Ceph Erasure Coded pool as the backend for OpenStack Cinder. I've created a replicated pool (volumes_meta) for metadata and an erasure-coded pool (volumes_data) for data, following the documentation here: https://docs.ceph.com/en/latest/rados/operations/erasure-code/ When I set rbd_pool to volumes_meta in cinder.conf, I receive an "Insufficient free virtual space" error, even though volumes_data has ample free space. This is because Cinder is calculating free space based on the metadata pool. When rbd_pool is set to volumes_data, Cinder correctly calculates free space based on the data pool. However, I then encounter an "RBD operation not supported" error during volume creation. I need Cinder to recognize the free space available in volumes_data while avoiding the "RBD operation not supported" error. I'm unsure how to configure this correctly and would appreciate any advice. The following is supplemental information. cinder.conf is: [ceph] volume_driver = cinder.volume.drivers.rbd.RBDDriver volume_backend_name = ceph rbd_pool = volumes_meta rbd_ceph_conf = /etc/ceph/ceph.conf rbd_flatten_volume_from_snapshot = false rbd_max_clone_depth = 5 rbd_store_chunk_size = 4 rados_connect_timeout = -1 rbd_user = cinder rbd_secret_uuid = <uuid> For example, if the pool usage is as follows, Cinder gets 1.6TiB as the pool free space: $ ceph df --- POOLS --- POOL ID PGS STORED OBJECTS USED %USED MAX AVAIL volumes_meta 4 32 40 KiB 24 189 KiB 0 1.6 TiB volumes_data 7 32 61 GiB 15.67k 92 GiB 2.80 2.1 TiB $ cinder get-pools --detail +-----------------------------+-----------------------------------------------------------------------------------+ | Property | Value | +-----------------------------+-----------------------------------------------------------------------------------+ | allocated_capacity_gb | 523 | | backend_state | up | | driver_version | 1.3.0 | | filter_function | None | | free_capacity_gb | 1592.07 <-★free capacity of volumes_meta | | goodness_function | None | | location_info | ceph:/etc/ceph/ceph.conf:<uuid>:cinder:volumes_meta | | max_over_subscription_ratio | 20.0 | | multiattach | True | | name | <hostname>@ceph#ceph | | qos_support | True | | replication_enabled | False | | reserved_percentage | 0 | | storage_protocol | ceph | | thin_provisioning_support | True | | timestamp | 2025-05-29T07:44:17.903149 | | total_capacity_gb | 1592.07 | | vendor_name | Open Source | | volume_backend_name | ceph | +-----------------------------+-----------------------------------------------------------------------------------+ OpenStack and Ceph versions are: $ ceph -v ceph version 17.2.8 (f817ceb7f187defb1d021d6328fa833eb8e943b3) quincy (stable) $ dnf list --installed | grep openstack-cinder openstack-cinder.noarch 1:21.3.2-1.el9s @centos-openstack-zed

[telemetry] Nominate Jaromír Wysoglad to Telemetry Core
by Juan Larriba 02 Jun '25

02 Jun '25

Hi, One of the things I wanted to do when becoming PTL of telemetry was to revive the interest in the community as I sensed that telemetry had been left a little bit behind from the rest of the projects. Since then, there has been a lot of movement: new Ceilometer features were added and even new projects (aethos, a prometheus-keystone proxy and grian-ui, a new metric displaying dashboard for Horizon) which has showed that the interest in gathering and displaying better and more scalable metrics is only growing. In these circumstances, the very small core contributor team needs to grow to keep up with all the influx of new features coming from the amazing community and I cannot think of anyone better than Jaromír Wysoglad to fulfill that role. Jaromír has been involved in the telemetry upstream community for years, tirelessly working to, among other things, make the whole telemetry suite to be compatible with Prometheus storage. He has implemented Prometheus compatibility with aodh, python-observabilityclient and many other things, including maintaining and improving the telemetry tempest test suite. Recently he created and is writing from scratch aetos, the new openstack-prometheus compatibility layer. I can't see a better contributor to the core group. If I don't hear any objections for one week, I'll add Jaromír to the group. Best Regards, Juan Larriba

Hi everyone, I installed OpenStack (DevStack). At first, I was able to create three images (Ubuntu, Debian, and Windows) in addition to the Cirros image. When I tried to add another image, everything got stuck. I couldn't add any images, and I got the infamous error 550. HttpException: 502: Server Error for url:

[ops] Matrix room created #openstack-ops:opendev.org
by Jeremy Stanley 31 May '25

31 May '25

Discussion during today's Ops Radio Hour at one point led to talking about real-time/synchronous chat platforms. Consensus seemed to be that it was worth starting a Matrix room on the OpenDev Collaboratory's homeserver for OpenStack Ops discussions, and see how it works out for everyone. Visit https://matrix.to/#/#openstack-ops:opendev.org if you want to check it out. If you're already logged into your Matrix account then the "Continue" button should take you right to the room. If you're not logged in then it should prompt you to pick a client (choose Element and continue in your browser if you don't feel like installing a client right now) and then to sign in or create an account. If you choose to create an account at that point, it painlessly walks you through creating one on matrix.org (though you can join with an account from any other homeserver instead, if you prefer). -- Jeremy Stanley
