[RelMgmt] Release team meeting cancelled Oct 24
by Sean McGinnis 23 Oct '19

23 Oct '19

Hey all, We discussed this in last week's meeting, but just a reminder that we will be skipping the release team meeting this Thursday, October 24. We are reaching the final deadline for the stable/queens branch to transition to Extended Maintenance. Please watch for anything related to that and help review final release patches if you can. Anything else that comes up, we can just address ad hoc in the #openstack-release channel. Thanks! Sean

"Large Scale SIG" discussion in Shanghai
by Thierry Carrez 23 Oct '19

23 Oct '19

Hi everyone, As OpenStack clusters grow larger, they hit scaling limitations in a number of components. To work around this problem, operators create multiple clusters. In recent visits to OpenStack users, I noticed a common theme around people interested in working to scale single clusters past their current limits. In the past we had various groups trying to identify bottlenecks or work on alternate technologies (RabbitMQ replacements): the Performance WG, or the "Large deployment" WG. However those groups had a bit of a wide focus, and/or are not active anymore. In Shanghai we'll discuss creating a "Large Scale SIG" that would tackle specifically those single-cluster-scaling issues. The idea is that by sharing performance analysis, it can help identify key bottlenecks. By pooling development resources, it can push fixes or new features to address those issues. I directly reached out to several people and organizations interested in working on that. Please join the session in Shanghai if you'll be present there and are interested in discussing this topic: https://www.openstack.org/summit/shanghai-2019/summit-schedule/events/24405… -- Thierry Carrez (ttx)

[tc][goal]: Ussuri community goal candidate 2: 'Switch remaining legacy jobs to Zuul v3 and drop legacy support'
by Ghanshyam Mann 23 Oct '19

23 Oct '19

Hello Everyone, As you might have seen on the ML about Ussuri community goal feedback for each proposed candidate [1], 2nd candidate is 'Switch remaining legacy jobs to Zuul v3 and drop legacy support' [2]. Andreas has briefed this goal in etherpad[2]. "Convert the remaining legacy jobs to Zuul v3 features. Grenade might be the largest open issue. This means especially that devstack-gate will not support Ussuri but only older releases. Having all jobs migrated to Zuul v3 native will allow easier maintenance and sharing between them. " Zuul has good documentation about migrating the legacy job to zuulv3 native. devstack and tempest have already migrated all their legacy jobs and so does many projects also ( if not all but few jobs for sure). Keeping legacy jobs are very costly not just in term of maintenance but also for doing the community-wide work. I have experienced the same during the migration of upstream CI from xenial - > Bionic in stein and IPV6 goal in Train. Currently, we do not have any volunteers to lead this goal. I would like to ask for the volunteer who can drive this goal do the pre-work about defining the goal and then be champion for this goal. Feel Free to reply to this email or ping me on #openstack-tc IRC channel.

[helm][loci][rpm][ironic] Please fill deployment tool capabilities
by Thierry Carrez 22 Oct '19

22 Oct '19

OpenStack-Helm, LOCI, RPM-packaging & Bifrost (ironic) folks: We recently started to display deployment tools capabilities over at: https://www.openstack.org/software/project-navigator/deployment-tools However OpenStack-Helm, LOCI, RPM Packaging and Bifrost display only the (default) component:keystone capability, because they were not filled when we we last asked[1][2]. As such, they look a bit sad. Please propose a patch to the following file: https://opendev.org/osf/openstack-map/src/branch/master/deployment_tools.ya… Capabilities are described in detail in: https://opendev.org/osf/openstack-map/src/branch/master/deployment_tools_ca… Let me know if you have any question, [1] http://lists.openstack.org/pipermail/openstack-discuss/2019-July/007585.html [2] http://lists.openstack.org/pipermail/openstack-discuss/2019-July/008150.html -- Thierry Carrez (ttx)

[kolla][ovs][networking] LLDP support within an internal network?
by Laurent Dumont 19 Oct '19

19 Oct '19

Hey everyone, Somewhat of a random question, but is there any built-in support within OVS to carry LLDP traffic between instances running on the same Tenant network? I know that linux-br will eat the LLDP traffic by default. So far, enabling LLDP on the port "qbr" allows the hypervisor to see the instances hosted on that hypervisor. The instances can see the hypervisor as well. That said, instances cannot see each other. All are residing within the same L2 network and are able to have L2 between each other. I am seeing the LLDP packets from the hypervisor arriving on the instance internal interface but nothing from the other instances. I am seeing the outgoing LLDP packets on each interfaces as well. Let me know if anything else is required. Thanks!

[cinder][tooz]Lock-files are remained

Hi, I'm using Queens cinder with the following setting. --------------------------------- [coordination] backend_url = file://$state_path --------------------------------- As a result, the files like the following were remained under the state path after some operations.[1] cinder-63dacb3d-bd4d-42bb-88fe-6e4180164765-delete_volume cinder-32c426af-82b4-41de-b637-7d76fed69e83-delete_snapshot In my understanding, these are lock-files created for synchronization by tooz. But, these lock-files were not deleted after finishing operations. Is this behaviour correct?

[oslo][security] Are config files vetted for ownership/permissions?
by Eric Fried 19 Oct '19

19 Oct '19

When $service loads up a config file like /etc/nova/nova.conf via oslo.config, is there anything that makes sure the dir and/or file are owned by the process user/group and have appropriate permissions? E.g. to prevent $hacker from modifying/replacing config opts and making $service do horrible things to my system/cloud. (I'm less concerned with $hacker seeing passwords etc., though I expect we would be accounting for both or neither.) efried .

[stable][oslo] Supporting qemu 4.1.0 on stein and older
by Ben Nemec 19 Oct '19

19 Oct '19

Hi, This is related to the FFE for train, but I wanted to discuss it separately because I think the circumstances are a bit different. Qemu 4.1.0 did not exist during the Stein cycle, so it's not clear to me that backporting bug fixes for it is valid. The original author of the patch actually wants it for Rocky, which is basically in the same situation as Stein. I should note he's willing to carry the patch downstream if necessary. On the one hand, it sounds like this is something at least one operator wants, but on the other I'm not sure the stable policy supports backporting patches to support a version of a dependency that didn't exist when the release was initially cut. I'm soliciting opinions on how to proceed here. Reference: https://review.opendev.org/#/c/686532 Thanks. -Ben

[openstack-operators] RBD problems after data center power outage

[nova] Stance on trivial features for driver configs without integration testing
by Matt Riedemann 18 Oct '19

18 Oct '19

This was brought up in the nova meeting today [1] as: "Do we have a particular stance on features to the libvirt driver for non-integration tested configurations, e.g. lxc [2] and xen [3], meaning if they are trivial enough do we just say the driver's quality warning on startup is sufficient to let them land since these are changes from casual contributors scratching an itch?" We agreed to move this to the mailing list. We don't have tempest jobs for the libvirt+lxc or libvirt+xen configurations (Citrix used to host 3rd party CI for the latter) and for the changes referenced they are from part-time contributors, minor and self-contained, and therefore I wouldn't expect them to build CI jobs for those configurations or stand up 3rd party CI. There are cases in the past where we've held features out due to lack of CI, e.g. live migration support in the vSphere driver. That's quite a bit different in my opinion because (1) it's a much more complicated feature, (2) there already was 3rd party CI for the vSphere driver and (3) there is a big rich corporation maintaining the driver so I figured they could pony up the resources to make that testing happen (and it eventually did). For these other small changes are we OK with letting them in knowing that the libvirt driver already logs a quality warning on startup for these configs [4]? In this case I am but wanted to ask and I don't think this sets a precedent as not all changes are equal.

[metrics] [telemetry] [stein] cpu_util
by Budai Laszlo 18 Oct '19

18 Oct '19

Hello all, the release release announce of ceilometer rocky is deprecating the cpu_util and *.rate metrics "* cpu_util and *.rate meters are deprecated and will be removed in future release in favor of the Gnocchi rate calculation equivalent." so we don't have them in Stein. Can you direct me to some document that describes how to achieve these with Gnocchi rate calculation? Thank you, Laszlo

[all][ceilometer][aodh][[docs] Possible error in Stein's Aodh documentation and how to configure cpu_util and pass on value to Aodh
by Gauri Sindhu 18 Oct '19

18 Oct '19

Hi all, As per the Rocky release notes <https://docs.openstack.org/releasenotes/ceilometer/rocky.html>, *cpu_util and *.rate meters are deprecated and will be removed in future release in favor of the Gnocchi rate calculation equivalent.* I have two doubts regarding this. Firstly, if the 'cpu_util' metric has been deprecated then why has it been used as an example in the documentation <https://docs.openstack.org/aodh/stein/admin/telemetry-alarms.html> in the 'Using Alarms' section? I've attached an image of the same. Secondly, I'm using OpenStack Stein and want to use the cpu_util or its equivalent to create an alarm. If this metric is no longer available then what do I pass onto Aodh to create the alarm? There seems to be no documentation that to help me out with this. Additionally, even if Gnocchi rate calculation is to be used, how am I supposed to transfer the result to Aodh? I also cannot seem to find the Gnocchi documentation. Regards, Gauri Sindhu

[aodh] [heat] Stein: How to create alarms based on rate metrics like CPU utilization?
by Bernd Bausch 18 Oct '19

18 Oct '19

Prior to Stein, Ceilometer issued a metric named /cpu_util/, which I could use to trigger alarms and autoscaling when CPU utilization was too high. cpu_util doesn't exist anymore. Instead, we are asked to use Gnocchi's /rate/ feature. However, when using rates, alarms on a group of resources require more parameters than just one metric: Both an aggregation and a reaggregation method are needed. For example, a group of instances that implement "myapp": gnocchi measures aggregation -m cpu --reaggregation mean --aggregation rate:mean --query server_group=myapp --resource-type instance Actually, this command uses a deprecated API (but from what I can see, Aodh still uses it). The new way is like this: gnocchi aggregates --resource-type instance '(aggregate rate:mean (metric cpu mean))' server_group=myapp If rate:mean is in the archive policy, it also works the other way around: gnocchi aggregates --resource-type instance '(aggregate mean (metric cpu rate:mean))' server_group=myapp Without reaggregation, I get quite unexpected numbers, including negative CPU rates. If you want to understand why, see this discussion with one of the Gnocchi maintainers [1]. *My problem*: Aodh allows me to set an aggregation method, but not a reaggregation method. How can I create alarms based on rates? The problem extends to Heat and autoscaling. Thanks much, Bernd. [1] https://github.com/gnocchixyz/gnocchi/issues/1044
