[tripleo] CI scenario001-standalone broken
by John Fulton 23 Jul '19

23 Jul '19

As per $subject [0]. scenario010 is affected too. This correlates with the promotion of the ceph-ansible 4rc11 RPM [1]. 001 jobs using rc9 do not have this problem. I'm looking into a fix, e.g. removing the storage7-ceph-nautilus-release tag from the rc11 package as TripleO CI uses the version of ceph-ansible which is tagged for release [2]. I'll keep this thread updated with the status and when it's fixed.

[Diversity] Grace Hopper Lead Co-Mentor(s) needed
by Amy Marrich 23 Jul '19

23 Jul '19

OpenStack has participated in Open Source Day at the Grace Hopper Conference for the last 5 years and this year it is in Orlando on October 3rd. Due to unforeseen circumstances we are one lead mentor short to participate this year and are looking for someone willing to help lead the session. The Anita Borg Institute will provide a ticket for the entire conference, the downside is you or your company will be responsible for your travel, lodging and food. This year CityNetwork is supplying the VM infrastructure for us to use. The session submitted is as follows: Participants will sign up for the necessary accounts needed to contribute to OpenStack and install Git and Gerrit. They will configure their systems and learn how to file bugs and review code within the Open Dev infrastructure. Due to time and resource requirements the groups will be given a virtual machine running Devstack in which to create their own theme for the Horizon Dashboard. The group will decide on which humanitarian effort they wish to support but suggestions will be provided for those groups that can not decide. The group will also work as a team to locate the necessary documentation on the OpenStack site if they have not done so in preparation. The selected Project Manager will lead these discussions as well as making sure efforts are staying on track to meet the deadline of the demonstrations. The Developers in the group will work to locate the necessary files and directories on the VM in order to complete their task. They will be in charge of creating/changing the necessary files to create a new theme utilizing SCSS and restarting any services needed to implement. The Graphic Designer if present will create any necessary graphics for the theme and will either scp them themselves to the virtual machine or provide to the developer. If there is no designated graphic designer the PM and devs will divide this duty up. After the themes are designed relevant files will be scped back down to the participants machines and they will be able to commit their code for review in a sandbox environment for other groups to review. If you are interested in participating please let me know by July 20th as we need to send additional information to the OSD folks on July 21st. Any questions please reach out on the lists, IRC, or privately! Thanks, Amy (spotz)

[Octavia]-Seeking performance numbers on Octavia
by Singh, Prabhjit 23 Jul '19

23 Jul '19

Hi I have been trying to test Octavia with some traffic generators and my tests are inconclusive. Appreciate your inputs on the following * It would be really nice to have some performance numbers that you guys have been able to achieve for this to be termed as carrier grade. * Would also appreciate if you could share any inputs on performance tuning Octavia * Any recommended flavor sizes for spinning up Amphorae, the default size of 1 core, 2 Gb disk and 1 Gig RAM does not seem enough. * Also I noticed when the Amphorae are spun up, at one time only one master is talking to the backend servers and has one IP that its using, it has to run out of ports after 64000 TCP concurrent sessions, id there a way to add more IPs or is this the limitation * If I needed some help with Octavia and some guidance around performance tuning can someone from the community help Thanks & Regards Prabhjit Singh

[ironic] Using ironic in a devstack environment to deploy OS on bare-metal host.
by Guannan GN2 Sun 23 Jul '19

23 Jul '19

Hi team, I met some problem when using ironic in a devstack environment to deploy OS on bare-metal host. By now I can successfully boot into the tiny os and set ip, also I can ping the ip from my devstack server. However, when the tiny os running some configuration, it will failed after about 5 minutes. I found some log information in "/var/log/ironic-python-agent.log" in the tiny os that may relate to the problem: "DEBUG oslo_concurrency.processutils [-] u'iscsistart -f' failed. Not Retrying. execute /usr/local/lib/python2.7/site-packages/oslo_concurrency/processutils.py:457" "DEBUG root [-] No iscsi connection detected. Skipping iscsi. Error: [Errno 2] No such file or directory _check_for_iscsi /usr/local/lib/python2.7/site-packages/ironic_python_agent/hardware.py:107" "WARNING root [-] The root device was not detected in 27 seconds: DeviceNotFound: Error finding the disk or partition device to deploy the image onto: No suitable device was found for deployment - root device hints were not provided and all found block devices are smaller than 4294967296B." "WARNING root [-] Can't find field vendor for device usb0 in device class net: IOError: [Errno 2] No such file or directory: '/sys/class/net/usb0/device/vendor'" "WARNING root [-] Can't find field vendor for device tunl0 in device class net: IOError: [Errno 2] No such file or directory: '/sys/class/net/tunl0/device/vendor'" "DEBUG root [-] No Mellanox devices found evaluate_hardware_support /usr/local/lib/python2.7/site-packages/ironic_python_agent/hardware_managers/mlnx.py:84" And when it deploy faild and I run command "openstack baremetal node show server-51", it will show following information on 'last_error' field: "Asynchronous exception: Node failed to deploy. Exception: Connection to agent failed: Failed to connect to the agent running on node f8794658-bc69-40cb-9673-be75f78ced21 for invoking command iscsi.start_iscsi_target. Error: ('Connection aborted.', BadStatusLine("''",)) for node" I'm trying to debug, but have not find the root cause, please give me your advice if someone have experience on it. Thank you!

[dev][magnum] Magnum event notifications not having relevant content related to clusters
by Emnauel Andrecut 23 Jul '19

23 Jul '19

I'm writing about Magnum event notifications that do not contain any relevant information about the related Cluster (missing cluster id, other attributes..) As I've seen the PyCADF library receives no targetId and so the id (and mostly any other id) is randomly generated. Do you plan to add more information about the cluster on create success/pending events. Or would you accept a patch that does that?

[all][meta-sig][containers-sig] Creation of Containers SIG
by Jean-Philippe Evrard 23 Jul '19

23 Jul '19

Hello everyone, I have discussed with some of you about the fact OpenStack is lacking a a group interested in sharing the practices for the building/management of OpenStack application containers. Every container related project is doing its own way (and it's probably fine), but very few experiences are shared (and it's sad). I started an etherpad [1] to see areas where container projects/people could collaborate. I already received significant feedback on how to improve some of my practices, so I think it's already a positive experience for me to have this group started. Anyway, long story short, I believe we should create a SIG for this, so I proposed the addition of the containers-sig into governance [2]. We have enough work to started this group nowadays (with documentation, bindep shared practices, and improvement of projects). I suppose technologies will evolve over time, so I expect a SIG is the best tool to do this job of *for example* gathering experience, as it's not really time bound, and it _is_ a quite special interest. If you're interested by learning what is going on in the container building world for OpenStack, please add [containers-sig] to your openstack-discuss topics watch list. Regards, Jean-Philippe Evrard (evrardjp) [1]: https://etherpad.openstack.org/p/containers-sig [2]: https://review.opendev.org/#/c/666001/

[nova] FYI to out-of-tree drivers: adding a positional argument to finish_revert_migration()
by Artom Lifshitz 22 Jul '19

22 Jul '19

[1] will most likely merge in its current shape or something very close to it. It adds a `migration` positional argument to the finish_revert_migration() virt driver method. `migration` is the, err, migration that's being reverted. If you have out of tree virt drivers, please update them to match this new method signature. Thanks! [1] https://review.opendev.org/#/c/668631/

[tripleo] TripleO CI Summary: Sprint 33
by Rafael Folco 22 Jul '19

22 Jul '19

Greetings, The TripleO CI team has just completed Sprint 33 / Unified Sprint 12 (Jun 27 thru Jul 17). The following is a summary of completed work during this sprint cycle: - Tested check jobs for periodic image/container builds on RHEL8 and resolved its dependencies on rhui repositories. - Enabled tripleo-repos to support RHEL8. - Addressed changes in kolla to support RHEL8. - Created a nodepool image on RDO for RHEL8 w/ elements and dependencies installed. - Improved container build script to consolidate kolla build logs and ease troubleshooting. - Manually pushed rhel containers to RDO registry and identified gaps in authentication workflow for the container build jobs using buildah tooling. - Modified scripts and post playbooks to upload RHEL8 overcloud images. - Created RHEL8 jobs to build a periodic pipeline in the RDO Software Factory and provide feedback for CentOS8 coverage. - Resumed scenario007 and featureset039 job updates upstream. - Promotion status: green on all branches at most of the sprint. The planned work for the next sprint [1] are: - Get RDO on RHEL8 build jobs working in periodic pipeline and bootstrap standalone and featureset001 jobs to consume RHEL8 images/containers. - Get featureset039 job to run novajoin tests and merge scenario007 job changes. - Review templates for branched and non-branched projects to have more control on what jobs are being run and reduce queue lengths. - Resume the design work for a staging environment to test changes in the promoter server for the multi-arch builds. The Ruck and Rover for this sprint are Marios Andreou (marios) and Rafael Folco (rfolco). Please direct questions or queries to them regarding CI status or issues in #tripleo, ideally to whomever has the ‘|ruck’ suffix on their nick. Ruck/rover notes are being tracked in etherpad [2]. Thanks, rfolco [1] https://tree.taiga.io/project/tripleo-ci-board/taskboard/unified-sprint-13 [2] https://etherpad.openstack.org/p/ruckroversprint13
