[ironic] Docs audit complete; results available
by Jay Faulkner 08 Jul '24

08 Jul '24

Hi all, Two PTGs ago, Ironic contributors had a topic about documentation -- we acknowledged our documentation was at times comprehensive, but at times incomprehensible :). This led us to enlist a professional technical writer, Dave Welsch, to assist. Dave has been working over the last few months to get feedback from Ironic users and contributors, as well as auditing our documentation and has put his final findings here: https://docs.google.com/document/d/1e9URuPHKNTx5QXdkCFAzsS0EAAxPJ-xQC4BEpDw… . Actionable bugs were a desired outcome of this, which was achieved. We filed several bugs against Ironic, tagged "docs-audit-2024" -- you can see the list here: https://bugs.launchpad.net/ironic/+bugs?field.tag=docs-audit-2024. I know that identifying issues is only part of the work needed; but it's our hope that by breaking this down and creating a path towards better docs, we'll be able to make it a less daunting task for contributors -- possibly even doable by folks from an outreachy-like program. Thanks for those who participated in this process. Feel free to reach out here if you have any questions, or to me privately. Thanks, Jay Faulkner

How to setup filters into oslo_notification/cinder
by Helder Ardachnikoff Gomes 08 Jul '24

08 Jul '24

I am working on a project with cinder and we keep listening to events from cinder through oslo messaging. We wish to set up cinder config in order to not receive events with the following event_type: volumes.exist. I read on chatgpt that I could setup my config like that: [oslo_messaging_notifications] driver = messagingv2 topics = notifications notification_format = both notification_filters = -volume.exist But, I am not quite confident about that, may someone help me ? -- _‘Esta mensagem é direcionada apenas para os endereços constantes no cabeçalho inicial.

[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!

Hi all, Is there a tool available in openstack, using which, as admin, we can list the operations executed by users like, vm operations , network related etc given their tenant uuid ? Do you think it is a good idea to have such a tool ? Thanks Y.G

when deleting an instance, its volume is not deleted
by kjme001＠gmail.com 08 Jul '24

08 Jul '24

I have the following problem, when deleting an instance, its volume is not deleted along with it, the volume remains and I then have to execute the command to detach the volume from the non-existent instance and then delete it. I don't know what could be causing this, the volume should probably be deleted together with the instance being deleted Thank you for your help

attach both virtio-scsi and virtio-blk to an instance
by Jiatong Shen 07 Jul '24

07 Jul '24

Hello, I am searching whether it is possible to use both virtio-scsi and virtio-blk at the same time for one instance. I knew it was possible to use each of them separately. I have this requirement because virtio-blk is not possible to support as many as devices like virtio-scsi, but we still want to keep virtio-blk for performance reasons and for legacy instances. Thank you for help. -- Best Regards, Jiatong Shen

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?

[openstack-helm] SQLAlchemy 2.0 support

Hi everyone! It seems like our db-init jobs are broken with the latest version of OpenStack because it doesn’t work with SQLAlchemy 2.0 2024-05-31 03:21:34,290 - OpenStack-Helm DB Init - INFO - Got DB root connection 2024-05-31 03:21:34,290 - OpenStack-Helm DB Init - INFO - Using /etc/keystone/keystone.conf as db config source 2024-05-31 03:21:34,292 - OpenStack-Helm DB Init - INFO - Trying to load db config from database:connection 2024-05-31 03:21:34,292 - OpenStack-Helm DB Init - INFO - Got config from /etc/keystone/keystone.conf 2024-05-31 03:21:34,331 - OpenStack-Helm DB Init - INFO - Tested connection to DB @ percona-xtradb-haproxy.openstack.svc.cluster.local:3306 as root 2024-05-31 03:21:34,332 - OpenStack-Helm DB Init - INFO - Got user db config 2024-05-31 03:21:34,332 - OpenStack-Helm DB Init - CRITICAL - Could not create database keystone Traceback (most recent call last): File "/tmp/db-init.py", line 112, in <module> root_engine.execute("CREATE DATABASE IF NOT EXISTS {0}".format(database)) AttributeError: 'Engine' object has no attribute 'execute' I was wondering if it makes sense to fix this, or if this is something that we should just take the time to simply replace with some sort of simple operator that creates manages/watches database CRs (if one doesn’t exist?) Thanks Mohammed
