[rabbitmq] Maximum Number of Sessions (8192) Reached
by Eugen Block 14 Aug '24

14 Aug '24

Hi *, I can't seem to find much about rabbitmq and logind, so I wanted to ask the list if anyone has encountered the same and if so, how they dealt with it. We're supporting a Victoria cluster (installed with our own deployment method) mostly controlled by pacemaker. And on the rabbit master node I see this warning constantly: ---snip--- 2024-07-29T14:09:23.552576+02:00 control01 su: pam_unix(su:session): session opened for user rabbitmq by (uid=0) 2024-07-29T14:09:24.450657+02:00 control01 su: pam_unix(su:session): session closed for user rabbitmq 2024-07-29T14:09:24.500356+02:00 control01 su: (to rabbitmq) root on none 2024-07-29T14:09:24.502370+02:00 control01 su: pam_systemd(su:session): Failed to create session: Maximum number of sessions (8192) reached, refusing further sessions. 2024-07-29T14:09:24.502681+02:00 control01 su: pam_unix(su:session): session opened for user rabbitmq by (uid=0) 2024-07-29T14:09:25.565203+02:00 control01 su: pam_unix(su:session): session closed for user rabbitmq 2024-07-29T14:09:25.609613+02:00 control01 su: (to rabbitmq) root on none ---snip--- Looking into loginctl list-sessions, almost all of them belong to rabbitmq and they have a very old timestamp (2023). I'm aware of older systemd versions which can't handle closing sessions correctly [0], but we can't upgrade at this time. Would enabling "linger" fix this (loginctl enable-linger rabbitmq) after a reboot? During the next maintenance window I would reboot control01 and watch how the other control nodes behave wrt rabbit login-sessions. But I'm wondering if somebody already has dealt with this? Thanks for any pointers! Eugen [0] https://www.suse.com/support/kb/doc/?id=000020549

Firewall as a Service - kolla ansible 2023.1
by Thamanna Farhath 07 Aug '24

07 Aug '24

Hello OpenStack Community, I hope this message finds you well. My name is Thamanna , and I am currently working with the OpenStack Kolla-Ansible deployment version 2023.1. I am interested in deploying Firewall as a Service (FWaaS) within our OpenStack environment. However, I have noticed that FWaaS is not available in the Kolla-Ansible 2023.1 version. Could anyone please provide guidance on the following points? 1. Is there an official or recommended way to integrate FWaaS with Kolla-Ansible 2023.1? 2. Are there any specific configurations or additional components required to enable FWaaS? 3. Has anyone in the community successfully deployed FWaaS with this version, and if so, could you share your experience and any potential challenges faced? 4. Are there alternative approaches or tools that you would recommend for deploying FWaaS in an OpenStack environment? Any help or pointers to relevant documentation would be greatly appreciated. Thank you in advance for your assistance!

Live migration fails
by Szabo, Istvan (Agoda) 07 Aug '24

Hi, I have couple of compute nodes where the live migration fails with existing vms. When I quickly spawn a vm and try live migration it works so I assume shouldn't be a big problem with the compute node. However I have many existing vms where it fails with a servername not found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 ERROR nova.conductor.tasks.migrate [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] [instance: 1517a2ac-3b51-4d8d-80b3-89a5614d1ae0] Unable to find record for source node servername on servername: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 WARNING nova.scheduler.utils [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] Failed to compute_task_migrate_server: Compute host servername could not be found.: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.605 227612 WARNING nova.scheduler.utils [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] [instance: 1517a2ac-3b51-4d8d-80b3-89a5614d1ae0] Setting instance to ACTIVE state.: ComputeHostNotFound: Compute host servername could not be found. /var/log/nova/nova-conductor.log:2021-04-21 14:47:12.672 227612 ERROR oslo_messaging.rpc.server [req-f4067a26-a233-4673-8c07-9a8a290980b0 dce35e6eceea4312bb0baa0510cef363 ca7e35079f4440c78bd9870724b9638b - default default] Exception during message handling: ComputeHostNotFound: Compute host am-osfecn-4025 Tried with this command: nova live-migration --block-migrate id.

[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

[election] [tc] Notification of non-candidacy; how it impacts TC diversity
by Jay Faulkner 01 Aug '24

01 Aug '24

Hi all, The nomination period for TC members / PTLs is coming up soon. I wanted to inform the community that I do not intend on standing for election for another year on the TC. Now is a good time, especially if you work somewhere other than Red Hat, to consider serving as a TC member to ensure our leadership team contains representation for all perspectives of OpenStack use. I'm happy to speak with anyone privately who is interested in running about what it's like to be on the TC, and to share some strategies I exercised to ensure the value of my TC membership was being communicated to leadership at my job. Thanks, Jay Faulkner Technical Committee Member
