Hey folks, We just agreed during today's meeting on having our first implementation review day this week. In order to make this day efficient, I proposed an etherpad for tracking our efforts https://etherpad.opendev.org/p/nova-caracal-status Shall you want the nova community to look at your changes, you should please add them into the etherpad in the very last section ('proposed bugfixes') and then me and a few other cores will curate that list. Tomorrow, we'll scrub the list of approved blueprints's patches and the bugfixes' ones that got approved as a review priority and we'll iterate over them. Please try to look at your Gerrit emails, you could get comments ;-) Thanks, -Sylvain

the volume cannot be deleted, it is in deleting state

hello, I'm having trouble deleting volumes in OpenStackl from a machine that no longer exists. How to execute cinder command reset-state --attach-status detached volume_name then I execute the command: # cinder delete volume_name Delete for volume cifar-10-copy failed: Invalid volume: Volume status must be available or error or error_restoring or error_extending or error_managing and must not be migrating, attached, belong to a group, have snapshots or be disassociated from snapshots after volume transfer. (HTTP 400) (Request-ID: req-b2d3f2e4-7855-4831-a68d-f6710cc97e94) ERROR: Unable to delete any of the specified volumes. then executes the command: cinder reset-state --state available volume_name and cinder delete volume_name Request to delete volume volume_name has been accepted. when I check: openstack volume show volume_name is: | status | deleting The volume is not being deleted, it is in the deleting state. This is a volume from a non-existent node, but the volume is still visible in OpenStack and cannot be deleted because it is in the deleting state. Maybe someone can tell me how to remove such a volume? Regards

I have observed an imbalance in the cluster based on the object.builder output. Is this possibly due to an ongoing rebalance process? Additionally, I'd like to confirm my understanding of 'min_part_hours.' Is it accurate to say that this parameter represents the number of hours an object needs to reside on a disk before it's considered for movement to another device during a rebalance? According to the Swift documentation, the default value is 24 hours. I'm curious if this value is applied to data written specifically by the rebalance process or if it also includes data written by other Swift services. object.builder, build version 775, id

[PTL][release][stable] Yoga - final release before branch becomes unmaintained
by Elõd Illés 14 Nov '23

14 Nov '23

Hi teams, According to the new process [1] Yoga should transition to Unmaintained as soon as possible (the original deadline for Extended Maintenance transition was planned to 2023-11-02). Similarly like before, teams have the final opportunity to release from stable/yoga before the branches will be *deleted*. In order to help the teams I have generated the list of the current *open* and *unreleased* changes in stable/yoga for repositories [2] where there are relevant patches. Please do a *final* release on Yoga if needed, before stable/yoga transition to Unmaintained. Feel free to edit and extend these lists to track your team's progress! *NOTE*: teams, please focus on wrapping up your libraries first if there is any concern about the changes, in order to avoid broken (final!!) releases!

[neutron][ptg] 2024.1/Caracal vPTG summary
by Brian Haley 13 Nov '23

13 Nov '23

Sorry for the slowness of getting this out. Here is a summary of the discussions we had over our two days of meetings, as well as other related sessions. The etherpad link can be found at [0]. Monday, October 23rd -------------------- # OS DBPerf Cross project session [1] This session was to talk about devstack performance issues that are believed to be caused by excessive querying by Neutron and Keystone. By default, when devstack "stacks", DB counter values are collected on each of the subsystems. Keystone and Neutron are outliers on how many SELECTs they issue during this process. As this is such a high-level number (4x to 10x other users), more work is required to understand what to fix, or if it's just normal behavior. For example, there is data from just a "stack" in addition to a tempest run that might be able to narrow things down here. Slawek and Miguel have agreed to work with the oslo.db team and Mike Bayer to get a better understanding of things here. Tuesday, October 24th --------------------- # Horizon For the last few cycles the Neutron team (Lajos) has been trying to deprecate usage of neutronclient. While this work is mostly complete, there is usage in Horizon that needs to be addressed. Lajos and Amotoki will be working on this. Full notes at [2] Wednesday, October 25th ----------------------- # Retrospective As is customary the team did a retrospective of the good, bad and what could be improved. In short, the Neutron team has met its goals from last cycle of completing Sqlalchemy 2.0 and RBAC work, while continuing to deliver a few new features and a lot of bug fixes. Most of the team are long time members which helps. One place we are working on is our job stability, and we continue to look at how to increase our review velocity. Our initial proposal on the latter is to have review marathons, perhaps on a monthly basis, since it has the double effect of closing bugs in the process. # EOL/EM cadence Train just went EOL. Decision was to propose Ussuri for EOL this cycle. # Bugs The total number of open bugs against Neutron has crept up since the beginning of Bobcat, from 726 to 760. I asked people to go through any bugs they own and make sure they are in the right state or should be closed. This is something we've done in previous cycles that has reduced our count by 1/3. # Gate We now have voting SLURP jobs! I.e. from Antelope to Caracal. Rodolfo has also been working on fullstack performance to try and reduce the runtime since we hit the 3 hour limit occasionally. Action item was taken by Slawek to see if there was overlap with other tests to see what could be removed. There was a question on what versions of OVS and OVN we use in our gate, and if there is a rule on when we should bump it, especially since sometimes new features require newer versions. Action item was taken by me to create a requirements doc similar to what Nova does for libvirt. # Neutronclient deprecation As discussed above, Horizon will be the focus this cycle. # OVN drivers for stadium projects There have been efforts recently to make stadium projects work with OVN, for example VPNaaS, FWaas and Taas. Main ask for for review cycles from core contributors. # Hidden SG rules in OVN Background is at [3]. Short story is that there are a minimum set of things that must be allowed for a VM to configure and use the network, like ARP, DHCP, ND, RA, RS and MLD. ML2/OVS adds hidden SG rules for these, and OVN allows some via ACLs. Our api-ref actually documents these requirements since stateless SGs needed to add them to function properly. The only service that is not enabled by default with stateless SGs is metadata. Question was regarding if we should make these rules visible in a read-only state. # S-RBAC This is a community goal and Neutron has completed the first phase and is part of phase 2 (service role), additional testing and nova/neutron token passing TBD. Phase 3 is the Project Manager role, which is not planned for this cycle. Thursday, October 26th ---------------------- # RFE reviews Discussed three active RFEs, two related to neutron-dynamic-routing, and one for OVN interconnection. Further discussion to take place in reviews and/or drivers meeting. # Metadata changes I noticed there were a number of changes to the metadata code in flight, so we went through them to try and create order out of the chaos. Basically, we will try and merge any bug fixes first since they need to be backported, followed by features and refactors. See the etherpad for more details. # OVN DB sync utility This tool is typically run after a migration or upgrade to make sure the Neutron and OVN DBs are in sync. A number of bugs have been fixed and backported, but there might be more. An action item was taken to try and make it more robust, and also make sure usage is documented. # Active-Active L3 gateway multi-homing Frode Nordahl gave an update on this OVN work that started in the Bobcat cycle, necessary to support multiple external gateways. A little over half the code is merged, plan is to complete the rest this cycle. # Nova cross-project Sean Mooney proposed that Neutron starts making certain extensions mandatory, for example, multiple port bindings, that make migration possible. Since then other features have been added that require it as well. Should we stop supporting backends that have not implemented it? We agreed this is a good step forward to what should be the minimum requirements of Neutron. In addition: - Nova will deprecate the legacy code path that doesn't use multiple bindings and log a warning, to be deleted in E release - Neutron will do the same for any similar code - Sean will provide a blueprint explaining which API extensions will be mandatory by Nova, as well as file a Neutron RFE bug - Eventually, we'll provide release notes and a ML thread for explaining all of this (we being the Nova and Neutron PTLs) Complete notes in Nova etherpad [4]. Thanks, and if you think I missed something please send updates or corrections. -Brian [0] https://etherpad.opendev.org/p/oct2023-ptg-neutron [1] https://etherpad.opendev.org/p/oct2023-ptg-os-dbperf-crossproject [2] https://etherpad.opendev.org/p/horizon-caracal-ptg [3] https://bugs.launchpad.net/neutron/+bug/1926515 [4] https://etherpad.opendev.org/p/nova-caracal-ptg#L80

[ops][cinder][kolla] Cinder + Ceph under high load can lead to timeouts and a failure state.
by Forrest Fuqua 13 Nov '23

13 Nov '23

In my setup of Cinder Zed + Ceph Quincy under very high loads there is a race condition due to a low timeout by default in Openstack Kolla in Cinder.conf of rados_connect_timeout = 5 This can lead to a duplicate volume trying to be made on ceph and cinder erroring out a VM Build in Nova. Nova: nova.exception.BuildAbortException: Build of instance a529f7d5-5a81-44f6-a1fd-93caa39b2439 aborted: Volume b476094b-075e-4dc7-b63e-5bb58a0a9229 did not finish being created even after we waited 30 seconds or 4 attempts. And its status is error. Cinder-Volume: File "/var/lib/kolla/venv/lib/python3.9/site-packages/cinder/volume/drivers/rbd.py", line 230, in __init__\n self.volume = driver.rbd.Image(rados_ioctx,\n', ' File "rbd.pyx", line 2894, in rbd.Image.__init__\n', "rbd.Timeout: [errno 110] RBD operation timeout (error opening image b'volume-b476094b-075e-4dc7-b63e-5bb58a0a9229' at snapshot None)\n"] --- File "/var/lib/kolla/venv/lib/python3.9/site-packages/eventlet/tpool.py", line 132, in execute\n six.reraise(c, e, tb)\n', ' File "/var/lib/kolla/venv/lib/python3.9/site-packages/six.py", line 719, in reraise\n raise value\n', ' File "/var/lib/kolla/venv/lib/python3.9/site-packages/eventlet/tpool.py", line 86, in tworker\n rv = meth(*args, **kwargs)\n', ' File "rbd.pyx", line 698, in rbd.RBD.clone\n', 'rbd.ImageExists: [errno 17] RBD image already exists (error creating clone)\n'] --- I can confirm that the volume does exist in Ceph now but no longer being tracked in Cinder, leading to a leftover artifact that eats up resources and a failed VM build. This seems like behavior that should be accounted for in some way.

[swift] Swiftstack Zone/DC decomission
by Muralikrishna Gutha 13 Nov '23

13 Nov '23

Certainly, here's a rewritten version: We currently utilize SwiftStack Object Storage to meet our object storage requirements, and our cluster has a Primary Zone/Secondary Zone topology. Recently, we attempted to remove/disable the Secondary Zone. However, upon doing so, we observed a concerning trend: the storage utilization in the Primary Zone rapidly increased, reaching approximately 90%. This surge was particularly notable due to the use of the 'tworeplicaperregion' policy. In an attempt to address this, we brought the Secondary Zone nodes back online, expecting Swift to redistribute the data back to these nodes and alleviate the storage strain on the Primary Zone. Despite reintegrating the Secondary Zone nodes into the cluster, we continue to witness a persistent rise in storage utilization within the Primary Zone. Interestingly, two out of the three nodes in the Primary Zone seem to bear the brunt of the data and tokens, while the third node is not receiving a proportional distribution of data. At this juncture, we are seeking guidance on potential configurations or adjustments, such as specific knobs, that could expedite the rebalance process. Our objective is to efficiently distribute the data across nodes, particularly in the Primary Zone, and optimize the overall storage utilization in our SwiftStack Object Storage cluster. Any insights or recommendations on tuning parameters for a swifter rebalance would be highly appreciated. Thanks, Murali -- This message may contain confidential and/or privileged information.
