[horizon] SCSS compilers
by Radomir Dopieralski 15 Nov '24

15 Nov '24

The openstack dashboard uses scss for styling, and so far we have used a python scss library for compiling those files to css for use in the browser. However, that library (pyscss) had in recent years some problems, and is not developed or supported by the authors anymore. So it's time to switch to something with a better support. The django-compressor plugin that we use for handling the compilation of files allows us to use any command-line tool to do the compilation, so we can switch to an scss compiler that is supported and used by the wider community. However, there are several options we can choose from: sassc python-libsass pysassc ruby-sass ruby-sassc node-node-sass Each of those would introduce a non-python dependency on the dashboard. The question for the packagers and distro maintainer is which of those tools would be preferable in terms of support, packaging, and maintenance for the long term? Do you have opinions? Maybe there is another tool that would be even better that I didn't find?

[OpenStack-Ansible] Major Upgrade from Yoga to Zed/Antelope
by Roby G 12 Nov '24

12 Nov '24

Hello everyone, Current environment: - Ubuntu 20.04 - OpenStack-Ansible Yoga - no LXC, services are installed bare metal - `install_method` is `distro` My goal is to upgrade this environment to Zed, or skip Zed and upgrade directly to Antelope, since Zed is also in Unmaintained state. What would you recommend? Which order should I follow - upgrade operating system or OpenStack first? The decision is a bit difficult as all 3 releases (Yoga, Zed and Antelope) support different Ubuntu versions in install_method distro and not the same one.

[kolla-ansible]: guidance needed for neutron setup
by turkey automation 12 Nov '24

12 Nov '24

Hey folks, I am new to Openstack and want to try it on KVM setup with 1 controller and 2 compute VMs. In my first attempt, I was able to install Openstack using kolla-ansible(2024.1 version) and also run-initonce completed without any issues. Now, I want to create instances that can access my back-bone i.e. KVM virtual network(192.168.121.x/24) but either floating IP concept or extending my KVM network to openstack(I don't know if it's feasible!) Some info about my infra: a. Controller 1: Interface eth0 has 192.168.121.5 IP address. eth1 has no IP. b. compute 1: Interface eth0: 192.168.121.10, eth1 has no IP. c. compute 2: interface eth0: 192.168.121.15, eth1 has no IP. What configuration do I need to enable in globals.yml and what all I need to do post deployment of openstack to ensure I have virtual instances on openstack that have IPs from 192.168.121.x network(dhcp can be controlled by KVM network?) and are accessible from other KVM based VMs that I created outside of openstack. I am a learner to please be elaborate if possible. Thanks in advance to the community. - Best regards!

Upstream Oslo IRC Meetings Are Back.
by Daniel Bengtsson 12 Nov '24

12 Nov '24

Hello everyone, I hope you are all doing well! I sent an email a while ago to reestablish the Upstream Oslo IRC meetings. With the removal of Eventlet, this makes even more sense. I have received two positive responses, and we also mentioned it during the PTG last week. I propose to hold these meetings every other Monday, starting today, at 4:00 PM UTC. Does this work for everyone? Thank you for your feedback! -- Daniel Bengtsson Software engineer

OpenStack Cinder - Volume-ID in cinder DB
by Harsh Ailani 12 Nov '24

12 Nov '24

Hello contributors, I am working on clone operation for a volumegroup and in that the volume ID auto-generated by OpenStack is not the one with which the clone volumes are being created on my IBM storage backend. This is as per design that IBM Storage backend will take the source-volume ID in the source-volumegroup and add a suffix to it while cloning. Now since there is a mismatch in the IDs between cinder and storage backend, because of which I am unable to perform any volume operations on this cloned volume. So, I was wondering if I can change the volume ID in cinder DB? I know that it’s a unique key and there is a limit of 36 characters for this field in cinder DB, but since I cannot change the volume in storage backend, I wanted to check if there is a way I can alter the volume ID in cinder DB? Kindly share your thoughts/suggestions on this matter. Thanks and Regards, Harsh Ailani

[Cinder][Ceph] Volumetria errada no cluster ceph
by lfsilva＠binario.cloud 07 Nov '24

07 Nov '24

Hello, I'm experiencing an issue with the volume usage of the Ceph cluster, which is currently used in OpenStack for volumes. I am working with Ceph version Octopus (15.2.17). When I run the ceph df command, I get this output: --- RAW STORAGE --- CLASS SIZE AVAIL USED RAW USED %RAW USED hdd 120 TiB 33 TiB 87 TiB 87 TiB 72.72 TOTAL 120 TiB 33 TiB 87 TiB 87 TiB 72.72 --- POOLS --- POOL ID PGS STORED OBJECTS USED %USED MAX AVAIL device_health_metrics 1 32 69 MiB 101 137 MiB 0 11 TiB images 2 256 1.3 TiB 166.90k 2.5 TiB 10.72 11 TiB vms 3 64 574 KiB 21 2.5 MiB 0 11 TiB volumes 4 2048 41 TiB 3.94M 82 TiB 79.42 11 TiB backups 5 1024 407 GiB 111.85k 818 GiB 3.63 11 TiB And when I run the rbd du -p volumes command, I get this total: NAME PROVISIONED USED <TOTAL> 14 TiB 8.3 TiB This "volumes" pool is currently set to replica 2, and mirroring is not enabled. I have checked for any locked or deleted snapshots but found none. I also ran a ceph osd pool deep-scrub volumes, but it didn't resolve the issue. Has anyone encountered this problem before? Could someone provide assistance?

Aye, that seems to have done it. Strange that this wasn't necessary for my old 1080 cards. Thanks!

Is HPET recommended for x86 instance?
by Jiatong Shen 04 Nov '24

04 Nov '24

Hello Community Experts, I found that to enable the HPET timer for x86 guests, the operator should set hw_time_hpet on the given image. By default, HPET is disabled. My question is what are the pros and cons for using HPET? Thanks. -- Best Regards, Jiatong Shen

[neutron][ovn-octavia-provider][octavia][ovn] Octavia OVN DBs sync cmd
by Rico Lin 04 Nov '24

04 Nov '24

Hi all I would like to raise attention to the patch set that introduces Octavia OVN DBs sync cmd. patches: https://review.opendev.org/q/topic:%22add-ovn-db-sync-utils%22 With command `octavia-ovn-db-sync-util {--debug}` It should allows us to do the OVN DB sync similar to what `neutron-ovn-db-sync-util` does. And thanks to Fernando Royo, the patches are small and earlier to review in focused functions. Would be great if we could have some more reviews for it. *Rico Lin*
