[puppet] Proposing core team clean up
by Takashi Kajinami 23 Aug '23

23 Aug '23

Hello, I went through the current core reviewers and found out that the current list includes some people no longer working in the OpenStack community. I'd like to propose removing the following persons from the core reviewer team as we haven't seen these people making any activity in the community recently. * Pradeep Kilambi - puppet-aodh, puppet-ceilometer, puppet-gnocchi, puppet-panko * Richard Megginson - puppet-keystone * Denis Egorenko - puppet-murano * Serg Melikyan - puppet-murano * Sergey Kolekonov - puppet-neutron * David Moreau Simard - puppet-openstack-integration * Yu xingchao - all modules Also, I confirmed that Wes Hayutin is no longer working for OpenStack and he agreed to retire from the core reviewer position. Thus I'll remove him as well. I'll be open for any feedback for one week to hear any thoughts/feedback about this removal. I'd like to take this moment to thank all people for their past work. We always welcome them back if they resume their work in this project. Thank you, Takashi KAJINAMI

[cloudkitty] question to the scope_key in cloudkitty
by Noah Elias Feldt 28 Jul '23

28 Jul '23

Hello! I am currently trying to get CloudKitty to work with the Prometheus Collector and PyScripts. I noticed that the scope_key for Prometheus can only be changed once in the global configuration file. This was a problem for me because we need different scope_keys for different metrics. Many of the metrics still need the scope key "tenant_id" and some others "project_id". I have found in the documentation of CloudKitty no way to change this for each metric, so I have internally changed something in the source code and added the function to set the scope_key for each metric individually. I just wanted to ask if you would be interested if I submit the small change upstream? Thank you. Regards Noah Feldt

[cinder] cinder-backup volume stuck in creating
by Satish Patel 27 Jul '23

27 Jul '23

Folks, I have configured nova and cinder with ceph storage. VMs running on ceph storage but now when i am trying to create a backup of cinder volume its getting stuck on creating and doing nothing. Logs also do not give any indication of bad. My cinder.conf [DEFAULT] enabled_backends = rbd-1 backup_driver = cinder.backup.drivers.ceph.CephBackupDriver backup_ceph_conf = /etc/ceph/ceph.conf backup_ceph_user = cinder-backup backup_ceph_chunk_size = 134217728 backup_ceph_pool = backups backup_ceph_stripe_unit = 0 backup_ceph_stripe_count = 0 restore_discard_excess_bytes = true osapi_volume_listen = 10.73.0.181 osapi_volume_listen_port = 8776 Output of "openstack volume service list" showing cinder-backup service is up but when i create a backup it's getting stuck in this stage and no activity. I am not seeing anything getting transferred to the ceph backups pool also. Any clue? or method to debug? # openstack volume backup list --all +--------------------------------------+------+-------------+----------+------+ | ID | Name | Description | Status | Size | +--------------------------------------+------+-------------+----------+------+ | bc844d55-8c5a-4bd3-b0e9-7c4c780c95ad | foo1 | | creating | 20 | +--------------------------------------+------+-------------+----------+------+

Re: [all] [oslo.messaging] Interest in collaboration on a NATS driver
by Tobias Urdin 22 Jul '23

Hello Kai, Great to hear that you’re interested! I’m currently just testing this as a POC directly in devstack so there is real-world testing (not should it yet I think, needs more development first).

Although I'm working with OpenStack for my employer at the moment, I'd do this in my spare time as I'm not sure that I can convince him to add another staging system with a full OpenStack installation just for developing a RabbitMQ replacement.

SNAT failure with OVN under Antelope
by Gary Molenkamp 13 Jul '23

13 Jul '23

Good morning, I'm having a problem with snat routing under OVN but I'm not sure if something is mis-configured or just my understanding of how OVN is architected is wrong. I've built a Zed cloud, since upgraded to Antelope, using the Neutron Manual install method here: https://docs.openstack.org/neutron/latest/install/ovn/manual_install.html I'm using a multi-tenent configuration using geneve and the flat provider network is present on each hypervisor. Each hypervisor is connected to the physical provider network, along with the tenent network and is tagged as an external chassis under OVN. br-int exists, as does br-provider ovs-vsctl set open . external-ids:ovn-cms-options=enable-chassis-as-gw For most cases, distributed FIP based connectivity is working without issue, but I'm having an issue where VMs without a FIP are not always able to use the SNAT services of the tenent network router. Scenario: Internal network named cs3319: with subnet 172.31.100.0/23 Has a router named cs3319_router with external gateway set (snat enabled) This network has 3 vms: - #1 has a FIP and can be accessed externally - #2 has no FIP, can be accessed via VM1 and can access external resources via SNAT (ie OS repos, DNS, etc) - #3 has no FIP, can be accessed via VM1 but has no external SNAT connectivity From what I can tell, the chassis config is correct, compute05 is the hypervisor and the faulty VM has a port binding on this hypervisor: ovn-sbctl show ... Chassis "8e0fa17c-e480-4b60-9015-bd8833412561" hostname: compute05.cloud.sci.uwo.ca Encap geneve ip: "192.168.0.105" options: {csum="true"} Port_Binding "7a5257eb-caea-45bf-b48c-620c5dff4b39" Port_Binding "50e16602-78e6-429b-8c2f-e7e838ece1b4" Port_Binding "f121c9f4-c3fe-4ea9-b754-a809be95a3fd" The router has the candidate gateways, and the snat set: ovn-nbctl show 92df19a7-4ebe-43ea-b233-f4e9f5a46e7c router 92df19a7-4ebe-43ea-b233-f4e9f5a46e7c (neutron-389439b5-07f8-44b6-a35b-c76651b48be5) (aka cs3319_public_router) port lrp-44ae1753-845e-4822-9e3d-a41e0469e257 mac: "fa:16:3e:9a:db:d8" networks: ["129.100.21.94/22"] gateway chassis: [5c039d38-70b2-4ee6-9df1-596f82c68106 99facd23-ad17-4b68-a8c2-1ff6da15ac5f 1694116c-6d30-4c31-b5ea-0f411878316e 2a4bbaf9-228a-462e-8970-0cdbf59086e6 9332c61b-93e1-4a70-9547-701a014bfd98] port lrp-509bba37-fa06-42d6-9210-2342045490db mac: "fa:16:3e:ff:0f:3b" networks: ["172.31.100.1/23"] nat 11e0565a-4695-4f67-b4ee-101f1b1b9a4f external ip: "129.100.21.94" logical ip: "172.31.100.0/23" type: "snat" nat 21e4be02-d81c-46e8-8fa8-3f94edb4aed1 external ip: "129.100.21.87" logical ip: "172.31.100.49" type: "dnat_and_snat" Each network agent on the hypervisors shows the ovn controller up : OVN Controller Gateway agent | compute05.cloud.sci.uwo.ca | | :-) | UP | ovn-controller The ovs vswitch on the hypervisor looks correct afaict and ovn ports bfd status are all forwarding to other hypervisors. ie: Port ovn-2a4bba-0 Interface ovn-2a4bba-0 type: geneve options: {csum="true", key=flow, remote_ip="192.168.0.106"} bfd_status: {diagnostic="No Diagnostic", flap_count="1", forwarding="true", remote_diagnostic="No Diagnostic", remote_state=up, state=up} Any advice on where to look would be appreciated.

[oslo] HTTP base direct RPC oslo.messaging driver contribution
by 室井雅仁 11 Jul '23

11 Jul '23

Hi oslo team, We'd like to contribute HTTP base direct RPC driver to the oslo.messaging community. We have developed the HTTP base driver internally. We have been using the driver in the production with over 10K hypervisors now. I checked the IRC meeting log of the oslo team[1], but there is no regluar meeting in 2023. Is it okay to submit oslo-spec[2] to propose the driver directly, or is there another good place to discuss the feature before submitting a spec? 1. https://meetings.opendev.org/#Oslo_Team_Meeting 2. https://opendev.org/openstack/oslo-specs best regards, Masahito
