[ops][upgrades][slurp] Seeking OpenStack Upgrade Case Studies
by Allison Price 08 May '25

08 May '25

Hi everyone, We have now published two case studies from OpenStack users who have implemented and are benefiting from the SLURP upgrade process[1]: Cleura[2] and Indiana University[3] I wanted to follow up to see if there are other organizations who have implemented the SLURP upgrade process who would like to tell your story? If we can get a few more, I would love to schedule an OpenInfra Live to deep dive into the improvements made around OpenStack upgrades and what users stuck on older releases should know. If you are interested, please let me know. And even if you’re not but you’re still using OpenStack—please remember to take the OpenStack User Survey[4] so we can learn more! Thanks!

[Cinder] : Group API query
by Harsh Ailani 05 May '25

05 May '25

Hello team, In one of our customer requirements we came across a use-case to move a volume from one group to another directly. Currently user needs to first remove the volume from the current group and add it to the new group. Wanted to know, if there is one direct cinder API or method to directly move the volume from one group to another ? Thanks and Regards, Harsh Ailani

Student Opportunity - CMU Summer Semester 2025
by Kendall Nelson 05 May '25

05 May '25

Hello All! Are any of you interested in mentoring students to work on any projects you have on the backlog? This is what I have from one of the Profs of the course: ------- To remind you of the ask from last year (and *call out differences for this year*): - We are looking for projects that a team of 4-5 students could tackle together with at least two mentors for each project. As we saw last year, mentors can certainly overlap projects if appropriate and they have the time. (Life happens and having the built-in mentor redundancy helps. I’ve had mentors get laid off, change jobs, and take summer vacation.) - Mentors are expected to meet student teams once a week for an hour (via any video conference setup folks want to use), and to be available by email during the rest of the week to answer any urgent questions. - *This summer we are running the class from 13 May to 31 July (11 weeks)*. - *We want to try teaching concurrently in both campuses Doha, Qatar (GMT+3) and Pittsburgh (GMT-5), USA. The entire course will be taught virtually this year, without a classroom.* I certainly did something similar a few years ago when I was teaching at Hopkins (20 students) with another group in Galway (16 students). The morning class in Pitt will be the afternoon in Doha. - *We likely have 15-20 students in each location, so if you had on the order of 4-5 team projects with mentors that fit the format, like last year, that would be fantastic. * - *We are considering going so far as to choose the teams across time zones to get them working remotely from the start.* Last year, after six weeks together in class and daily stand-ups, the students scattered home away from Doha, and all of them worked remotely the last four weeks. They proved they could work remotely together. Of course, the relationships with mentors have always been remote. The profs in Doha and Pitt want to try remote from the beginning. (I have a few concerns but I’m also always up to experiment on students.) - We post the projects on the first day of class and will organize the teams in that first couple of days, so student teams are introduced to their mentors in the first week of class and expected to organize that first meeting to begin the project learning curve. That’s when mentors point students at any tutorials and bootstrap materials, recommended getting started materials, etc. - We have set the expectations with the students that they will be spending 20-40 hours of time per week on the project. It is an internship-like experience. - *Two co-teachers run classes on three days a week for 50 minutes, and I will guest lecture a collection of classes. *(Last year, there was just the real professor and I.) - The three of us will provide a coaching session with each team to ensure they are working with the mentors well. - Students generally have Windows or Mac laptops, but we have teaching assistants on each site that we can start to prep any other access to resources they might need. - As with last year, mentors have a lot of freedom to experiment. Some have run joint sessions if they are mentoring more students for learning curves. Some have run Slack or Discord channels. ------ So, who is interested in working with students? Please let me know if you have any additional questions. -- Kendall Nelson *Senior Upstream Developer Advocate* The OpenInfra Foundation <https://openinfra.dev/>

[manila] Removal of the Standalone CephFS NFS protocol helper in Epoxy
by Ashley Rodriguez 01 May '25

01 May '25

Hi zorillas! As per subject line, we will be deprecating the standalone CephFS NFS protocol helper in this cycle. This is following our deprecation warning we put out in 2024.1 / Caracal [1] [2]. We've supported using a clustered Ceph NFS service since the Zed release. We've also added upgrade helpers to migrate from a standalone NFS-Ganesha service to the ceph-orch-deployed clustered NFS service; this code was backported to stable/2023.1 (Antelope). Although the upgrade path is disruptive, there is a UX improvement in Manila to ease this migration through surfacing “preferred” export paths. Moving forward, deployments must have “cephfs_nfs_cluster_id” in your configuration, otherwise the driver will fail to start. Manila will not make any export changes to NFS-Ganesha, so upgrading manila without an NFS cluster will mean that only the control plane is not going to work; but, data plane will remain unaffected. To assist migration, admins can also configure "cephfs_ganesha_export_ips" (or alternatively, "cephfs_ganesha_server_ip") alongside "cephfs_nfs_cluster_id". Setting these options will allow the CephFS driver to report additional export paths. These additional export paths will have the "preferred" metadata key set to False. Best, Manila team [1] https://review.opendev.org/c/openstack/manila/+/912648 [2] https://docs.openstack.org/manila/2024.2/configuration/shared-file-systems/…

30 Apr '25

Hello. I am going with ovn for my system but when I use vxlan and geneve, my instance cannot get full bandwidth(12 gbps)-instance to instance with private network. It is ok if I use vlan or floating ip for instances. My env: Openstack 2025.1 Kolla Ansible master-2025.1 Ubuntu 22.04 with uplink 25gbps x 2 for bonding, lacp 802.3ad, layer3+4 Ps give me some points. Thank Nguyen Huu Khoi

Hello Everyone, As discussion topics are less during biweekly meetings (most of the time it's just me), I am updating the RBAC policy pop-up meeting to occur monthly on the first Monday of each month. The next meeting will be on May 5th. NOTE: We still have many projects to complete the RBAC goal, and you do not need to wait for the meeting to ask RBAC-related help/queries, feel free to reach out to me on IRC/ML. - https://wiki.openstack.org/wiki/Consistent_and_Secure_Default_Policies_Popu… - https://review.opendev.org/c/opendev/irc-meetings/+/948569 -gmann
