[openstack][kolla-ansible]about upgrading openstack
by Nguyễn Hữu Khôi 04 Aug '24

04 Aug '24

Hello. I read this doc about upgrading openstack https://docs.openstack.org/kolla-ansible/latest/user/operating-kolla.html But I would like to know if We install a new kolla-ansible(version to upgrade) on the new deployment host, apply changes with password.yml, global.yml and multinode and keep old /etc/kolla/config. Finally, we use kolla-ansible deploy instead of kolla-ansible upgrade. Are these steps ok? Pls correct me if I am wrong. Thank you. Regards Nguyen Huu Khoi

[RALLY 4.1.0] Verifier reconfigure fails when in "no admin" mode
by Jean-François TALTAVULL 16 Jul '24

16 Jul '24

Hi All, I'm using a Rally (4.1.0) deployment with existing users and no admin credentials. So the command "rally env show" outputs "admin": null in the json and it's ok. But the problem is that the command "rally verify configure-verifier -reconfigure" fails with: "rally_openstack.common.credential.OpenStackCredential() argument after ** must be a mapping, not NoneType" I've been struggling with this error for a number of hours with no results :-( Any idea ? I looked for a known bug in launchpad but found nothing. Thanks, Jean-Francois

[swift] Weird log corruption or something more serious?
by Sam Morrison 15 Jul '24

Hi, We are debugging a weird issue with our swift cluster (currently running 2.29.2) We got a report from a user that they were getting upload failures and then sent us this from their logs: 2024-06-25 23:30:06,829 | swiftclient.service | ERROR | Object PUT failed: https://swift-host/v1/PROJECT_ID_A/prod_result/195e5e8e-334a-11ef-ba70-0a58… 401 Unauthorized [first 60 chars of response] b'<html><h1>Unauthorized</h1><p>This server could not verify t' (txn: txab25fcfcf3354bbbaf105-00667b52fe) Searching our logs for that transaction ID I found: 203.101.227.241 127.0.0.1 25/Jun/2024/23/30/06 PUT /v1/AUTH_PROJECT_ID_B/nexus-migration/nexus-data/blobs/default/content/vol-27/chap-25/6bc30bae-4f5e-40a8-bc63-096679af1a58.bytes HTTP/1.0 401 - rclone/v1.59.0%2Cpython-swiftclient-4.2.0 gAAAAABme1L7tlfE... - 131 - txab25fcfcf3354bbbaf105-00667b52fe - 0.0440 - - 1719358206.765954018 1719358206.809994936 0 Note this is a completely different project ID from our side, timestamp is correct too.

[skyline][tc] Graduating skyline out of the "Emerging Projects" list
by Goutham Pacha Ravi 09 Jul '24

09 Jul '24

Hi, We were discussing in a recent TC meeting that Skyline seems to be ready to lose the "Emerging project" tag [1]. The arguments supporting it's graduation are: - The project is actively maintained, and has had consistent releases since the Zed release [2][3][4][5] - The project is being used in production cloud deployments [6] - Operators have requested skyline's inclusion in deployment and configuration management projects [7][8] Wu Wenxiang / Skyline team - is this assessment correct? If yes, are there any objections to removing Skyline from [1]? If it helps, the project team can re-assess the OpenStack project requirements we have [9] and work on any deficiencies.

[Neutron] Is there a way to work around "External network not reachable from subnet" by setting a static route?
by Florian Haas 08 Jul '24

08 Jul '24

Hi everyone, here's a question I've been chewing on for some time. Please bear with me while I illustrate the background. 1. Suppose you have a regular (internal) Neutron network, subnet, and router. You now plug the subnet into the router and set an external gateway. You then create a port on the subnet. You associate a floating IP with that port. All is well. 2. Suppose instead you do plug the subnet into the router, but you don't set an external gateway on it. You try to associate a floating IP with that port. This creates a BadRequest because: "External network <uuid> is not reachable from subnet <uuid>". 3. Suppose instead you do set an external gateway on the router, but you don't connect the subnet to it. Again, you try to associate a floating IP with that port. This also creates a BadRequest because: "External network <uuid> is not reachable from subnet <uuid>". So far, so good. Up to this point, everything is behaving according to intuitive expectations. Now suppose we have * the external network, * an "outer" internal network, * a Neutron router connecting the two (that is, the router has the external network as its gateway, and has an interface to the "outer" subnet), * an "inner" internal network, * a Nova server (let's call that the "gateway"), which connects the "inner" and "outer" networks, a * another Nova server (the "worker") that sits on the "inner" network. (Suppose, for the sake of discussion, that the "gateway" runs some kind of web application firewall or other virtual security appliance, and the "worker" is a general-purpose Linux instance.) Now I can give the Neutron router a static route so that traffic to the "inner" network uses the "gateway" as its nexthop. Provided the "gateway" does its forwarding correctly, this means that the "worker" has internet connectivity via the "gateway" (which, in turn, achieves this via the router). This, too, works fine for outbound connections originating with the "worker". If I now want to assign a floating IP to the "worker", then routing-wise there really should be no problem: the router should take care of SNAT/DNAT, it would translate the floating IP into a private IP on the "inner" network, would consult its routing table, and throw packets for that "inner" network to the "gateway" to handle, per the static route that's been set. But when I try to associate a floating IP to the "worker" in this scenario, I *still* get the "External network not reachable from subnet" error, because the associated internal check[1] does not take the existing static route into account. This appears to have been an issue in other contexts as well: the defunct Tricircle project appears to have worked around this limitation via a service plugin that just omitted that check.[2] Now my questions are these: 1. Shouldn't this be fixed in core, instead? It would seem to me like the default check is too simplistic, but I might be missing something. 2. Is there a way to make this check take static routes into account, other than providing a service plugin like Tricircle used to do? Thanks! Cheers, Florian References: [1] get_router_for_floatingip(): https://opendev.org/openstack/neutron/src/commit/ebed620aafdff75a05fb5d42ad… [2] get_router_for_floatingip(): https://opendev.org/openstack/tricircle/src/commit/8db8fb30f5757c46a953962d…

Kolla-Ansible Issues
by Alexandra Rong 05 Jul '24

05 Jul '24

Hello OpenStack-Ansible team, We are students in Germany studying Business Informatics. Currently, we have a project where we need to build an OpenStack environment using Kolla-Ansible. Our goal is to use Gnocchi and CloudKitty to gather metrics on the usage of the VMs in OpenStack. We tried following the official Kolla-Ansible deployment guide but encountered issues starting Kolla-Ansible, as shown in the attached screenshots. Could you possibly help us? Best regards, Felix and Alexandra Ansible.cfg: Error: All-in-one:

[CloudKitty] query regarding ElasticSearch usage
by Rafael Weingärtner 04 Jul '24

04 Jul '24

Hello OpenStack community and users of CloudKitty! There have been some discussions in our bi-weekly meetings and vPTG meetings regarding the deprecation and removal of ElasticSearch support as a storage backend. Therefore, this e-mail is to consult/query users regarding ElasticSearch users. If there are no people using it anymore with CloudKitty, we are considering the alternative of removing it and maintaining only the OpenSearch support. We would like to hear back from you guys. Let me know if you are using ElasticSearch, and if you intend to stick with it. Also, do you guys feel the need to improve something in its support in CloudKitty. Thanks in advance for your feedback! -- Rafael Weingärtner

[nova] volume information was duplicated when Live Migration failed

To whom it may concern Hi. I encountered an issue with OpenStack where volume information was duplicated when Live Migration failed. Could you please provide a solution to this issue?

Hi All, I'm trying to do a test multinode deploy using 2023.2 I have letsencrypt_webserver and letsencrypt_lego contsainers running and I'm seeing random traffic in the /var/log/kolla/letsencrypt/letsencrypt-webserver-access.log so fairly confident they're plumbed through to the public internet properly, but I don't seem to be getting certificates. how can I trigger a renewal attempt so I can maybe see what I've screwed up?
