Problems with Cinder and iSCSI
by Alexander Luedtke 02 Mar '25

02 Mar '25

Hello Everyone, I have a really strange problem with iSCSI, Cinder, Kolla setup. 1. What I want to do: I did setup with kolla 1 Controller, 4 Compute nodes and 2 storage nodes (iSCSI, Cinder, LVM). Kolla Deploying works fine, all Machines can find all others. 2. Problem: happens when I try to create an instance * Im creating an new instance what fails because the cinder volume couldn't be "mounted" on the compute node * What I checked then: o storage2 (the 2. cinder iscsi storage node) is available (by ping ) from the compute node o Port 3260 on storage2 is not reachable from compute node o so checking storage2 + the volume was created on LVM (checked with lvs) + Port 3260 is not available local too + it looks like that cinder creates an iSCSI target and deletes it after some seconds ... no reason shown (I activated debug mode in Kolla in the hope to see more but no ...) Did anyone have some similar behavior or can give me a hint where else to look ? Thanks a lot for your help ! best Alex Logfile of the storage2 node /var/log/kolla/cinder/cinder-volume.log: the following lines came 5-6 times and then nothing more. 2025-03-03 08:17:02.625 42 DEBUG cinder.volume.drivers.lvm [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] Updating volume stats _update_volume_stats /var/lib/kolla/venv/lib/python3.12/site-packages/cinder/volume/drivers/lvm.py:227 2025-03-03 08:17:02.626 42 DEBUG oslo_concurrency.processutils [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] Running cmd (subprocess): sudo cinder-rootwrap /etc/cinder/rootwrap.conf env LC_ALL=C vgs --noheadings --unit=g -o name,size,free,lv_count,uuid --separator : --nosuffix cinder-volumes execute /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_concurrency/processutils.py:349 2025-03-03 08:17:03.057 42 DEBUG oslo_concurrency.processutils [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] CMD "sudo cinder-rootwrap /etc/cinder/rootwrap.conf env LC_ALL=C vgs --noheadings --unit=g -o name,size,free,lv_count,uuid --separator : --nosuffix cinder-vo lumes" returned: 0 in 0.432s execute /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_concurrency/processutils.py:372 2025-03-03 08:17:03.059 42 DEBUG oslo_concurrency.processutils [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] Running cmd (subprocess): sudo cinder-rootwrap /etc/cinder/rootwrap.conf env LC_ALL=C lvs --noheadings --unit=g -o vg_name,name,size --nosuffix --readonly ci nder-volumes execute /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_concurrency/processutils.py:349 2025-03-03 08:17:03.483 42 DEBUG oslo_concurrency.processutils [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] CMD "sudo cinder-rootwrap /etc/cinder/rootwrap.conf env LC_ALL=C lvs --noheadings --unit=g -o vg_name,name,size --nosuffix --readonly cinder-volumes" returne d: 0 in 0.425s execute /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_concurrency/processutils.py:372 2025-03-03 08:17:03.485 42 DEBUG oslo_concurrency.processutils [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] Running cmd (subprocess): sudo cinder-rootwrap /etc/cinder/rootwrap.conf env LC_ALL=C lvs --noheadings --unit=g -o size,data_percent --separator : --nosuffix /dev/cinder-volumes/cinder-volumes-pool execute /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_concurrency/processutils.py:349 2025-03-03 08:17:03.899 42 DEBUG oslo_concurrency.processutils [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] CMD "sudo cinder-rootwrap /etc/cinder/rootwrap.conf env LC_ALL=C lvs --noheadings --unit=g -o size,data_percent --separator : --nosuffix /dev/cinder-volumes/ cinder-volumes-pool" returned: 0 in 0.414s execute /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_concurrency/processutils.py:372 2025-03-03 08:17:03.900 42 DEBUG oslo_concurrency.processutils [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] Running cmd (subprocess): sudo cinder-rootwrap /etc/cinder/rootwrap.conf env LC_ALL=C lvs --noheadings --unit=g -o vg_name,name,size --nosuffix --readonly ci nder-volumes execute /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_concurrency/processutils.py:349 2025-03-03 08:17:04.319 42 DEBUG oslo_concurrency.processutils [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] CMD "sudo cinder-rootwrap /etc/cinder/rootwrap.conf env LC_ALL=C lvs --noheadings --unit=g -o vg_name,name,size --nosuffix --readonly cinder-volumes" returne d: 0 in 0.418s execute /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_concurrency/processutils.py:372 2025-03-03 08:17:04.320 42 DEBUG cinder.manager [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] Notifying Schedulers of capabilities ... _publish_service_capabilities /var/lib/kolla/venv/lib/python3.12/site-packages/cinder/manager.py:202 2025-03-03 08:18:02.626 42 DEBUG oslo_service.periodic_task [None req-c3be57e8-eeac-4b14-99c7-f3f10474a3cf - - - - - -] Running periodic task VolumeManager.publish_service_capabilities run_periodic_tasks /var/lib/kolla/venv/lib/python3.12/site-packages/oslo_service/periodic_task. py:210

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.1/R-4)
by Goutham Pacha Ravi 02 Mar '25

02 Mar '25

Hello Stackers, Last week, we passed milestone-3 of the 2025.1 "Epoxy" release cycle [1]. With this, we're at the tail end of this release cycle. Next week, we'll be tagging release candidates across the board for all project deliverables following the "cycle-with-rc" release model. By the end of this week, Project Team Leads and liaisons are expected to submit release cycle highlights, capturing important updates that operators and users can expect from each project in the Epoxy release. In the past week, election officials finalized the results of the PTL and TC elections for the next release cycle: 2025.2 "Flamingo" [2][3]. Please join me in congratulating these individuals. I'm especially excited to see a long lineup of first-time PTLs: Matt Crees (mattcrees) leading Blazar, Omer Schwartz (oschwart) leading Designate, Cyril Roelandt (croelandt) leading Glance, Artem Goncharov (gtema) leading Keystone, Dale Smith (dalees) leading Magnum, René Ribaud (uggla) leading Nova, Juan Larriba leading Telemetry, and Jiasirui leading Venus. The community is grateful to past PTLs, many of whom have mentored these new leaders. Additionally, Michal Nasiadka (mnasiadka) has joined the OpenStack TC, replacing Slawek Kaplonski (slaweq), who has served on the TC since the Zed cycle. Thank you for your service, and congratulations! I'd also like to thank Slawek and Ian Y Choi (ianychoi) for their service as the election officials. Later this week, the North American section of the OpenInfra Community will gather in Pasadena, CA, alongside SCALE 2025 [4]. I invite you to join community leaders at the OpenInfra Leadership meet-and-greet event if you're attending. Helena Spease (hspease) tells me there'll be cake to celebrate OpenStack's 15th birthday! [5] === Weekly Meeting === The OpenStack TC met on 2025-02-25 over IRC [6]. The election results were discussed, and we paid special attention to "leaderless" project teams—i.e., teams where no PTL nominations were accepted before the deadline: Oslo, Barbican, Masakari, OpenStack Charms, and Zaqar. Of these, the Oslo team decided to continue following a Distributed Project Leadership model, while the remaining teams are pending PTL appointments. The TC is in discussions with potential candidates. We also shared the TC's PTG Planning Etherpad [7] during the meeting. The TC and the community are encouraged to add topics to this etherpad. The next meeting of the OpenStack TC will be held simultaneously on video (Zoom) and IRC (#openstack-tc on OFTC) tomorrow, 2025-03-04. Please find the agenda for this meeting on the meeting wiki [8]. I hope you'll be able to join us. Remember that you can propose topics for the weekly TC meetings by editing this wiki page. Please leave your IRC nick next to the topic proposed so we can call on you during the meeting. === Governance Proposals === ==== Merged ==== Add TC/PTL results from 2025.2 election | https://review.opendev.org/c/openstack/governance/+/942507 Add Extra-ACs to the tech committee repos | https://review.opendev.org/c/openstack/governance/+/942296 ==== Open for Review ==== Appoint Mauricio Harley as PTL for Barbican | https://review.opendev.org/c/openstack/governance/+/942907 Switch back Oslo to DPL model | https://review.opendev.org/c/openstack/governance/+/942793 Resolve to adhere to non-biased language | https://review.opendev.org/c/openstack/governance/+/934907 === Upcoming Events === - 2025-03-06: SCALE 2025 + OpenInfra Days NA (Link) - 2025-03-11: OpenInfra Board Meeting (Link) - 2025-04-02: OpenStack 2025.1 ("Epoxy") Release - 2025-04-07 - 2025-04-11: OpenInfra PTG === How to Contact the TC === You can reach the TC in several ways: - Email: Send an email with the tag [tc] on this mailing list. - IRC: Ping us using the 'tc-members' keyword on the #openstack-tc IRC channel on OFTC. - Meetings: Join us at our weekly meeting.

Remove config drive of instances
by Pardhiv Karri 02 Mar '25

02 Mar '25

Hi, We are on the Openstack Queens version. We added the config drive option during its build but never used it. How can we remove it? The "OpenStack server delete --no-config-drive" option isn't available due to the older version we are using. What is the best way to eliminate it, hopefully without rebooting the instances? Thanks, IM

[release] Release countdown for week R-4, Mar 03 - 07
by Elõd Illés 28 Feb '25

28 Feb '25

Development Focus ----------------- We just passed feature freeze! Until release branches are cut, you should stop accepting featureful changes to deliverables following the cycle-with-rc release model, or to libraries. Exceptions should be discussed on separate threads on the mailing-list, and feature freeze exceptions approved by the team's PTL. Focus should be on finding and fixing release-critical bugs, so that release candidates and final versions of the 2025.1 Epoxy deliverables can be proposed, well ahead of the final 2025.1 Epoxy release date. General Information ------------------- We are still finishing up processing a few release requests, but the 2025.1 Epoxy release requirements are now frozen. If new library releases are needed to fix release-critical bugs in 2025.1 Epoxy, you must request a Requirements Freeze Exception (RFE) from the requirements team before we can do a new release to avoid having something released in 2025.1 Epoxy that is not actually usable. This is done by posting to the openstack-discuss mailing list with a subject line similar to: [$PROJECT][requirements] RFE requested for $PROJECT_LIB Include justification/reasoning for why a RFE is needed for this lib. If/when the requirements team OKs the post-freeze update, we can then process a new release. A soft String freeze is now in effect, in order to let the I18N team do the translation work in good conditions. In Horizon and the various dashboard plugins, you should stop accepting changes that modify user-visible strings. Exceptions should be discussed on the mailing-list. By March 27th, 2025 this will become a hard string freeze, with no changes in user-visible strings allowed. Actions ------- stable/2025.1 branches should be created soon for all not-already-branched libraries. You should expect 2-3 changes to be proposed for each: a .gitreview update, a reno update (skipped for projects not using reno), and a tox.ini constraints URL update. Please review those in priority so that the branch can be functional ASAP. The Prelude section of reno release notes is rendered as the top level overview for the release. Any important overall messaging for 2025.1 Epoxy changes should be added there to make sure the consumers of your release notes see them. Upcoming Deadlines & Dates -------------------------- RC1 deadline: March 14th, 2025 (R-3 week) Final RC deadline: March 28th, 2025 (R-1 week) Final 2025.1 Epoxy release: April 2nd, 2025 Project Teams Gathering (virtual): April 7th-11th, 2025 Előd Illés irc: elodilles @ #openstack-release

Issues with installing Zun on Compute node
by Vaibhav 28 Feb '25

28 Feb '25

I was trying to install openstack 2024.2 zun on compute node. and following the page https://docs.openstack.org/zun/2024.2/install/compute-install.html for installation. I am facing the issue of docker "--cluster-store" support. I am using Docker 27.5 version. Reading the documentation online, i am confused. Some places it is, mentioned that it is fixed. and some places it suggest to uses docker 22. At few places in your mail you have mentioned to stop using kuryr and use CNI. And official documentation still says to use --cluster store. What is the current state and the correct solution. Please guide me. Vaibhav

[Openstack-ansible][cinder-volume] deletion of snapshot after creating a volume from it..
by Danish Khan 27 Feb '25

27 Feb '25

Dear All, Is there a way we can delete a volume who has a snapshot available? I have created a volume from snapshot and now we have a full chain of snapshots and volumes that we can't delete. But I need only the last volume to be available. If not then what is the best use case for snapshot? or Should I assume that if I create a snapshot and then create a volume from that snapshot then I need to keep the old volume and snapshot always. Regards, Danish
