[openstack-ansible] [masakari]
by Budai Laszlo 19 Jun '24

19 Jun '24

Dear All, I'm evaluating Masakari for instance HA and I need to install it using openstack-ansible. I'm doing it initially in a small test cluster (3 controller, and 3 compute). The install went trough and now when I'm checking the status of the corosync cluster I see the following: root@worker1:~# crm_mon -1 Cluster Summary: * Stack: corosync * Current DC: worker2 (version 2.1.2-ada5c3b36e2) - partition with quorum * Last updated: Wed Jun 19 16:02:01 2024 * Last change: Wed Jun 19 15:29:37 2024 by hacluster via crmd on worker2 * 3 nodes configured * 0 resource instances configured Node List: * Online: [ worker1 worker2 worker3 ] Active Resources: * No active resources root@worker1:~# is it normal that there are no resources configured? What about the fencing, how should I configure it? Are you aware of any documentation where I could find mori info about configuring fencing (especially in the context of openstack-ansible)? Thank you for any advice. Kind regards, Laszlo

[devstack][packstack] Quick install of OpenStack Ussuri
by Francesco Di Nucci 19 Jun '24

19 Jun '24

Hi, I was planning on taking the COA exam, and as it's still tested on the Ussuri release I wanted to create a local install to get used to the differences with current releases. I have tried with PackStack but there seem to be some never fixed bug with Galera setup, and with PackStack I wasn't able to make it work on any "supported" OS [bionic|stretch|jessie|f30|f31|opensuse-15.2|opensuse-tumbleweed|rhel8] (either the Python version is too old, or packages install is not supported on EL8, or repositories have been taken down etc etc...) Are there any pre-configured VMs that can be used for training? Or does anyone know on which OS (outside of the ones before) could a Ussuri setup with Devstack run? Thank you in advance Francesco Di Nucci

[Rootwrap] Package sudoers file for rootwrap?
by Francesco Di Nucci 19 Jun '24

19 Jun '24

Hello, I was reviewing the sudoers entries I'm using for rootwrap (https://wiki.openstack.org/wiki/Rootwrap) and I was wondering - would it be possible to sudoers config in the packages? Maybe as files to be placed in /etc/sudoers.d, especially as apart from Nova the usage is not well documented, and I had to use kolla's files as examples Best regards Francesco Di Nucci

Using RDMA in OpenStack managed virtual machines
by Jiatong Shen 18 Jun '24

18 Jun '24

Hello, community, I would like to ask about best practices for using infiniband and RoCEv2 for openstack managed virtual machines. I am a newbie to this area so any information is appreciated. The use case right now is basically for training/inferencing deep learning applications, for example connecting to parallel filesystem through RDMA (IB/RoCEv2). I've done a very basic search through the internet and found mainline code provides sriov-agent which could do basic VF passthrough. There is also a project named mellanox-networking which looks like it could handle IB but seems not to be updated since Train release. All of the above mentioned codes, seems to not handle switches/routers which in my opinion is not complete (at least for RoCEv2, seems PFC/ECN etc should configure switch). Is there any available implementation for using IB/RoCEv2 in production? Thank you very much for sharing insights. -- Best Regards, Jiatong Shen

How to get an empty file /etc/resolv.conf ?
by iamotvertov＠gmail.com 18 Jun '24

18 Jun '24

When creating a virtual machine, entries like "search openstacklocal" or "domain openstacklocal" always appear in the /etc/resolv.conf file. I want that after creating any virtual machine in the file /file the lines “search openstacklocal” or “domain openstacklocal” were missing. I found a way to change these lines, but my goal is completely missing them. How can this be implemented? Which function needs to be fixed and where? I use Openstack train

[operations][nova] Mi grate to shared /var/lib/nova/instances
by Francesco Di Nucci 18 Jun '24

18 Jun '24

Hello, AFAIK live migration requires to have /var/lib/nova/instances shared between the compute nodes (eg. through a NFS export)- If this has not been configured initially and each compute node has its own folder, is it possible to merge them somehow without disruptive effects? Regards Francesco Di Nucci

[neutron] Neutron server WSGI module, plugin workers
by Rodolfo Alonso Hernandez 18 Jun '24

18 Jun '24

Hello Neutrinos: I would like to highlight something I found during the implementation of [1]. The periodic workers are currently not executed when the WSGI module is configured when using the ML2/OVS mechanism driver (ML2/OVS is still under development). In order to fix that, I've pushed the following patches: * Set the Neutron server workers name: https://review.opendev.org/c/openstack/neutron/+/922090/ * Add a new process to spawn the plugin services in the Neutron server: https://review.opendev.org/c/openstack/neutron/+/922110 * (devstack) [Neutron] Add a new Neutron service: neutron-services-server: https://review.opendev.org/c/openstack/devstack/+/922125 Now we have periodic and experimental jobs using WSGI, I've pushed https://review.opendev.org/c/openstack/neutron/+/922182 to test both the Neutron and the devstack patches. Regards. [1] [OVN] Add support for WSGI mod: https://bugs.launchpad.net/neutron/+bug/1912359

[openstack-ansible][release] Delayed 2024.1 (Caracal) Trailing release
by Dmitriy Rabotyagov 17 Jun '24

17 Jun '24

Hi folks, As you might have noticed, the final release for 2024.1 (Caracal) is being delayed now for over a week. This has happened due to finding a couple of nasty bugs during more thorough testing of the upgrade path from Antelope by our community members, which happened after RC1 was published. Currently we are on track and known issues was fixed. We are waiting now for SHA bumps to land for the final RC3 which will be used as a 29.0.0 tag. I do hope that it will be done by the end of this week. Sorry for the inconveniences.
