[placement][ptg] Allocation Partitioning
by Chris Dent 17 Apr '19

17 Apr '19

>From the etherpad [1]: * do we need this? * what is it? * who is going to drive it? As as I recall, allocation partitioning (distinct from resource provider partitioning) is a way of declaring that a set of allocations below to a specific service. This is useful as a way, for example, of counting instances spawned via nova. Right now it is possible to count vcpus, ram and disk but if something besides nova is making allocations using those resource classes how do we distinguish? Of course it's important to also ask "should we distinguish?". If there's a concept of unified limits does it matter whether a VCPU is consume by _this_ nova or something else if they are consumed by the same user? This functionality is closely tied to resource provider partitioning. In a complex placement scenario, where placement is managing multiple instance spawning tools, in multiple cloud-like things, it seems like both would be needed. The ongoing work to implement quota counting in placement [2] has a workaround for instances not being counted in placement, but the "more than one nova per placement" limitation has to be documented. How urgent is this? Is there anyone available to do the work this cycle? How damaging is it to punt to U? What details are missing in the above description?

Routed networks and FIP gateway assignments
by Syd Logan 16 Apr '19

16 Apr '19

I'm currently learning about routed networks and have a lab that is implementing a 3 tier leaf spine and have a question. I know that I can create a subnet from which FIP gateway IP addresses are consumed, e.g., openstack subnet create demo-floating-ip-agent-gateway-subnet \ --subnet-range 198.51.100.0/24 --no-dhcp \ --service-type 'network:floatingip_agent_gateway' \ --network demo-ext-net In videos from past OpenStack summits such as this https://youtu.be/XnXSwCSHc4U drawings show that the subnet is used within a single segment's compute nodes, and I can believe that would work. What isn't clear is whether the same subnet should be used across multiple segments, or the intent is for each segment defined in the routed network to have a unique subnet from which these FIP gateway IPs are assigned, e.g., some other segment would be using, say 198.52.100.0/24. In the non-routed network setup where I leanred about DVR it was pretty clear only one subnet was allowed, but what is the best practice/intent for routed nets? Thanks. syd

by Sergey Nikitin 16 Apr '19

16 Apr '19

Hello everyone, As you mentioned there are some inaccuracies in stats on stackalytics.com. It happened because of outdated Prod env. At this moment we are in a process of migration to the new env. All data on this env is fresh and accurate. So the problem will be solved soon. -- Best Regards, Sergey Nikitin

[gentoo] Looking for members to help maintain OpenStack packages on Gentoo
by Matthew Thode 16 Apr '19

16 Apr '19

I'm considering disbanding the Gentoo OpenStack project and switching to sole maintainership of the project. So far I'm the only active maintianer in the project that I can see. I'm looking for others that are interested in helping maintain the openstack ebuilds. It's fairly easy as an ongoing thing with two major releases a year (which starts an update of 160 or so packages). It's python based and I've found maintaining the ebuilds to be very easy individually if that helps. There are other actions that'd be helpful as well. Some arm64 stage work (catalyst builds these) to then do some arm64 diskimage-builder work to work on building VM images for other arches (openstack or 'vanilla'). Please respond if you are intrested in joining. I've also emailed the Gentoo developer list separately with the same request. Thanks, -- Matthew Thode

[placement][ptg] Keeping osc-placement healthy
by Chris Dent 16 Apr '19

16 Apr '19

>From the etherpad [1]: * It is behind (in microversions) and sometimes hard to remember * It's functional tests require a working devstack, which is a bit meh * Maybe something like https://vcrpy.readthedocs.io/en/latest/ could help (reasonable given microversions) * (edleafe) It might be useful to have an osc-placement lead (czar? princess? mayor?) who can devote some of their time to this and help coordinate others. I might be able to rustle up some cycles. Not much to add to the above. What additional ideas to people have. Who (in addition to Ed) has some time to care about osc-placement? What do people think of vcrpy? What else? [1] https://etherpad.openstack.org/p/placement-ptg-train -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent tw: @anticdent
