[kolla][ptg] Kolla Ussuri PVPTG (Partially Virtual PTG)
by Radosław Piliszek 08 Nov '19

08 Nov '19

Hello Everyone, As you may already know, Kolla core team is mostly not present on summit in Shanghai. Instead we are organizing a PTG next week, 7-8th Nov (Thu-Fri), in Białystok, Poland. Please let me know this week if you are interested in coming in person. We invite operators, contributors and contributors-to-be to join us for the virtual PTG online. The time schedule will be advertised later. Please fill yourself in on the whiteboard [1]. New ideas are welcome.

[nova][ptg] Virtual PTG
by Eric Fried 08 Nov '19

08 Nov '19

Hello nova contributors and other stakeholders. As you are aware, nova maintainers will be sparser than usual at the ussuri PTG. For that reason, and also because it promotes better inclusion anyway, I'd like us to do the majority of decision making via the mailing list. The PTG is still a useful place to talk through design ideas, but this will give those not attending a voice in the final direction. To that end, I call your attention to the etherpad [1]. As usual, list your topics there. And if your topic is something for which you only need (or wish to start with) in-person discussions (e.g. "I'd like to do $thing but could use some help figuring out $how"), you're done. But if what you're shooting for is discussion leading to some kind of decision, like... - My spec has been stalled because we can't decide among N different approaches; we need to reach a consensus. - My feature is really important; can we please prioritize it for ussuri? ...then in addition to putting your topic on the etherpad, please initiate a (separate) thread on this mailing list, including [nova][ptg] in your subject line. Some of these topics may be resolved before the PTG itself. Others may be discussed in Shanghai. However, even if a consensus is reached in person, expect that decision to be tentative pending closure of the ML thread. Thanks, efried [1] https://etherpad.openstack.org/p/nova-shanghai-ptg

CPU pinning blues
by Albert Braden 06 Nov '19

06 Nov '19

I'm following this document to setup CPU pinning on Rocky: https://www.redhat.com/en/blog/driving-fast-lane-cpu-pinning-and-numa-topol… I followed all of the steps except for modifying non-pinned flavors and I have one aggregate containing a single NUMA-capable host: root@us01odc-dev1-ctrl1:/var/log/nova# os aggregate list +----+-------+-------------------+ | ID | Name | Availability Zone | +----+-------+-------------------+ | 4 | perf3 | None | +----+-------+-------------------+ root@us01odc-dev1-ctrl1:/var/log/nova# os aggregate show 4 +-------------------+----------------------------+ | Field | Value | +-------------------+----------------------------+ | availability_zone | None | | created_at | 2019-10-30T23:05:41.000000 | | deleted | False | | deleted_at | None | | hosts | [u'us01odc-dev1-hv003'] | | id | 4 | | name | perf3 | | properties | pinned='true' | | updated_at | None | +-------------------+----------------------------+ I have a flavor with the NUMA properties: root@us01odc-dev1-ctrl1:/var/log/nova# os flavor show s1.perf3 +----------------------------+-------------------------------------------------------------------------+ | Field | Value | +----------------------------+-------------------------------------------------------------------------+ | OS-FLV-DISABLED:disabled | False | | OS-FLV-EXT-DATA:ephemeral | 0 | | access_project_ids | None | | disk | 35 | | id | be3d21c4-7e91-42a2-b832-47f42fdd3907 | | name | s1.perf3 | | os-flavor-access:is_public | True | | properties | aggregate_instance_extra_specs:pinned='true', hw:cpu_policy='dedicated' | | ram | 30720 | | rxtx_factor | 1.0 | | swap | 7168 | | vcpus | 4 | +----------------------------+-------------------------------------------------------------------------+ I create a VM with that flavor: openstack server create --flavor s1.perf3 --image NOT-QSC-CentOS6.10-19P1-v4 --network it-network alberttest4 but it goes to error status, and I see this in the logs: 2019-10-30 16:17:55.590 3248800 INFO nova.virt.hardware [req-d0c2de13-db23-41bd-8da3-34c68ff1d998 2cb6757679d54a69803a5b6e317b3a93 474ae347d8ad426f8118e55eee47dcfd - default 7d3a4deab35b434bba403100a6729c81] Computed NUMA topology CPU pinning: usable pCPUs: [[4], [5], [6], [7]], vCPUs mapping: [(0, 4), (1, 5), (2, 6), (3, 7)] 2019-10-30 16:17:55.595 3248800 INFO nova.virt.hardware [req-d0c2de13-db23-41bd-8da3-34c68ff1d998 2cb6757679d54a69803a5b6e317b3a93 474ae347d8ad426f8118e55eee47dcfd - default 7d3a4deab35b434bba403100a6729c81] Computed NUMA topology CPU pinning: usable pCPUs: [[0], [1], [2], [3], [4], [5], [6], [7]], vCPUs mapping: [(0, 0), (1, 1), (2, 2), (3, 3)] 2019-10-30 16:17:55.595 3248800 INFO nova.filters [req-d0c2de13-db23-41bd-8da3-34c68ff1d998 2cb6757679d54a69803a5b6e317b3a93 474ae347d8ad426f8118e55eee47dcfd - default 7d3a4deab35b434bba403100a6729c81] Filter AggregateInstanceExtraSpecsFilter returned 0 hosts 2019-10-30 16:17:55.596 3248800 INFO nova.filters [req-d0c2de13-db23-41bd-8da3-34c68ff1d998 2cb6757679d54a69803a5b6e317b3a93 474ae347d8ad426f8118e55eee47dcfd - default 7d3a4deab35b434bba403100a6729c81] Filtering removed all hosts for the request with instance ID '73b1e584-0ce4-478c-a706-c5892609dc3f'.

I create s1.perf3 VMs and they land on us01odc-dev1-hv002 and the XML shows that they are correctly pinned. When us01odc-dev1-hv002 is full then they start failing again. What should I be looking for here? What could cause one apparently identical hypervisor to fail AggregateInstanceExtraSpecsFilter while another one passes? In the nova-compute log of the failing hypervisor I see this: 2019-10-31 10:43:01.147 1103 INFO nova.compute.resource_tracker [req-dda65a9c-9d0a-4888-b4cb-0bf4423dd2f3 - - - - -] Instance 4856d505-c220-4873-b881-836b5b75f7bb has allocations against this compute host but is not found in the database. 2019-10-31 10:43:01.148 1103 INFO nova.compute.resource_tracker [req-dda65a9c-9d0a-4888-b4cb-0bf4423dd2f3 - - - - -] Final resource view: name=us01odc-dev1-hv003.internal.synopsys.com phys_ram=128888MB used_ram=38912MB phys_disk=1208GB used_disk=297GB total_vcpus=8 used_vcpus=6 pci_stats=[] Openstack can't find a VM with UUID 4856d505-c220-4873-b881-836b5b75f7bb. There are no VMs on hv003 but I can create a non-pinned VM there and it works. Do I have a "phantom" VM that is consuming resources on hv003? How can I fix that?

Hello, We use 2 types of volume, like volumes and volumes_ceph. I can update the quota for volumes quota using "cinder quota-update --volumes=20 project-id" But for volumes_ceph, the above CLI failed with volumes_ceph un recognised option.. Any suggestions here?

[ospurge] looking for project owners / considering adoption
by Adam Harwell 04 Nov '19

04 Nov '19

I haven't seen much activity on this project in a while, and it's been moved to opendev/x since the opendev migration... Who is the current owner of this project? Is there anyone who actually is maintaining it, or would mind if others wanted to adopt the project to move it forward? Thanks, --Adam Harwell
