[kolla-ansible] Galera DR across multiple datacenters
by Jahns, Jay 13 Nov '23

13 Nov '23

We currently run OpenStack on top of two datacenters, and we need to ensure we have datacenter redundancy for the database. With this, we would have 2-3 nodes in each DC running galera. Its been recommended by multiple people that we use an externally managed database server (or cluster) that has its own redundancies built around the two DC layout, and not have kolla manage that. Is there a way we can use kolla to deploy a galera cluster per DC, and use that to provide redundancy in the event that we lose one of the DCs? We were currently looking at proxysql but folks have recommended against it. Thanks.

[neutron][ovs][kolla-ansible] Does neutron-openvswitch-agent required for sriov only compute node
by Satish Patel 12 Nov '23

12 Nov '23

Folks, I have an openstack cloud just running SRIOV workload, We don't have a requirement to run standard vms on compute nodes. Currently I have noticed neutron-sriov-agent and openvswitch-agent running on all compute nodes. Technically in my case I don't have any use of openvswitch-agent so I am planning to get rid of those agents to reduce pressure on the neutron-server. Just wanted to check with export if that is ok to not run ovs agent. I hope neutron-server won't freak out.

[release] Release countdown for week R-20, Nov 13-17
by Elõd Illés 10 Nov '23

10 Nov '23

Development Focus ----------------- The Caracal-1 milestone is next week, on November 16th, 2023! Project team plans for the 2024.1 Caracal cycle should now be solidified. General Information ------------------- Libraries need to be released at least once per milestone period. Next week, the release team will propose releases for any library which had changes but has not been otherwise released since the 2023.2 Bobcat release. PTL's or release liaisons, please watch for these and give a +1 to acknowledge them. If there is some reason to hold off on a release, let us know that as well, by posting a -1. If we do not hear anything at all by the end of the week, we will assume things are OK to proceed. NB: If one of your libraries is still releasing 0.x versions, start thinking about when it will be appropriate to do a 1.0 version. The version number does signal the state, real or perceived, of the library, so we strongly encourage going to a full major version once things are in a good and usable state. Upcoming Deadlines & Dates -------------------------- Caracal-1 milestone: November 16th, 2023 Előd Illés irc: elodilles @ #openstack-release

[OpenstackAnsible][cinder][newtron][nova]
by Tecstim 10 Nov '23

10 Nov '23

Hi, I am testing to deploy a multi-node environment. I tried openstack-helm because I thought it was cool to have containers and virtual machines in the same environment, but it is not very stable and seems difficult to operate. Now I am testing with openstack ansible. I just deployed AIO in a VM. I want to achieve this: Use a physical interface for networks with vlans, and the gateway and dhcp are managed outside openstack. Use NetApp NFS as storage for persistent data of lxd containers of the openstack-ansible, images for VMs and deplyment and use this https://docs.openstack.org/cinder/2023.2/configuration/block-storage/driver… to create volumes for vms.

[all] Failing sqlalchemy-tips jobs should now be passing again
by Stephen Finucane 10 Nov '23

10 Nov '23

Just FYI, for projects that have sqlalchemy-tips jobs that have been failing recently, they should now be passing again. The root cause was neither sqlalchemy nor alembic but rather oslo.utils [1]. It was fixed in oslo.utils 6.3.0 which was released [2] roughly an hour ago. A recheck should be sufficient to clear errors and as these tips jobs only run on master there should be no issues with stable branches. A further point to add: while I appreciate that broken gates are never a good thing, I would be careful making these jobs non-voting. I've already seen a few instances where SQLAlchemy 2.0 support has regressed and I for one have no desire to re-herd cats as we push to get SQLAlchemy uncapped in the coming weeks. If this happens again then we can re-examine things, naturally. Cheers, Stephen [1] https://review.opendev.org/c/openstack/oslo.utils/+/900343 [2] https://review.opendev.org/c/openstack/releases/+/900382

[kolla-ansible] group_vars question
by Satish Patel 09 Nov '23

09 Nov '23

Folks, I have multiple kinds of nic in cloud and want to configure SRIOV so instead of defining the following variable for each compute node, I would like to create a group and apply config to the groups. Am I right here to define groups like the following or is there a better way to handle this? What is the default path of group_vars and hosts_vars in kolla-ansible? # vi /etc/kolla/group_vars/sriov_eno49.yml neutron_sriov_physnet_mappings: physnet1: eno49 # vi /etc/kolla/group_vars/sriov_eno50.yml neutron_sriov_physnet_mappings: physnet1: eno50 # vi multinode [sriov_eno49] comp1 comp2 comp3 [sriov_eno50] comp4 comp5 comp6

[kolla-ansible] Not to install openvswitch on sriov_agent compute nodes
by Satish Patel 09 Nov '23

09 Nov '23

Folks, I have pure sriov compute nodes where I don't want to deploy openvswitch because SRIOV agents do pass through PCI bugs to VM directly. Currently all my SRIOV compute nodes have two agents running. neutron_openvswitch_agent neutron_sriov_agent I don't think "neutron_openvswitch_agent" has any role on sriov compute nodes. If I want to tell kolla-ansible not to deploy neutron_openvswitch_agent on X compute node then how do I tell. Are there any easy ways to turn it off? ~S
