Live migration fails
by Szabo, Istvan (Agoda) 06 Aug '24

06 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.

[puppet] Proposing core team clean up
by Takashi Kajinami 23 Aug '23

23 Aug '23

Hello, I went through the current core reviewers and found out that the current list includes some people no longer working in the OpenStack community. I'd like to propose removing the following persons from the core reviewer team as we haven't seen these people making any activity in the community recently. * Pradeep Kilambi - puppet-aodh, puppet-ceilometer, puppet-gnocchi, puppet-panko * Richard Megginson - puppet-keystone * Denis Egorenko - puppet-murano * Serg Melikyan - puppet-murano * Sergey Kolekonov - puppet-neutron * David Moreau Simard - puppet-openstack-integration * Yu xingchao - all modules Also, I confirmed that Wes Hayutin is no longer working for OpenStack and he agreed to retire from the core reviewer position. Thus I'll remove him as well. I'll be open for any feedback for one week to hear any thoughts/feedback about this removal. I'd like to take this moment to thank all people for their past work. We always welcome them back if they resume their work in this project. Thank you, Takashi KAJINAMI

[designate] How to avoid NXDOMAIN or stale data during cold start of a (new) machine
by Christian Rohmann 23 Nov '22

23 Nov '22

Hello openstack-discuss, I have a designate setup using bind9 as the user-serving DNS server. When starting a machine with either very old or no zones at all, NXDOMAIN or other actually stale data is sent out to clients as designate is not done doing an initial full sync / reconciliation. * What is the "proper" way to tackle this cold-start issue and to keep the bind from serving wrong data? ** Did I miss on any options to handle this startup case? * What is the usual runtime for an initial sync that you observe in case the backend DNS server has no zones at all anymore? Regards Christian

[all] Deprecated Zuul queue syntax
by Clark Boylan 16 Sep '22

16 Sep '22

Hello, Zuul deprecated declaring shared queues at a pipeline level with release 4.1.0 [0]. Zuul's current plan is to stop accepting this form of configuration with a future 7.0.0 release. More details on what needs to change can be found in Zuul's reminder notice on the Zuul mailing list [1]. I expect we have about a month before the v7 release which should give us plenty of time to fix this. If we don't fix this before the v7 release the expected fallout will be that these project branches will not have any pipelines defined, which means no Zuul jobs will run against that project branch until the configs are updated. I've marked this for everyone because 98 repositories are affected, and I'm not sure listing them all in the subject would be productive. Here is the list of affected repos: openstack/adjutant openstack/ansible-collection-kolla openstack/ansible-role-collect-logs openstack/ansible-role-tripleo-modify-image openstack/barbican openstack/barbican-tempest-plugin openstack/barbican-ui openstack/blazar openstack/blazar-tempest-plugin openstack/ceilometer openstack/cinderlib openstack/cloudkitty openstack/cloudkitty-tempest-plugin openstack/cyborg-tempest-plugin openstack/designate openstack/designate-dashboard openstack/designate-tempest-plugin openstack/devstack-gate openstack/ec2-api openstack/ec2api-tempest-plugin openstack/freezer openstack/freezer-tempest-plugin openstack/heat openstack/heat-dashboard openstack/heat-tempest-plugin openstack/horizon openstack/ironic openstack/ironic-inspector openstack/ironic-lib openstack/ironic-prometheus-exporter openstack/ironic-python-agent openstack/ironic-tempest-plugin openstack/kayobe openstack/kayobe-config openstack/kayobe-config-dev openstack/kolla openstack/kolla-ansible openstack/kuryr openstack/magnum openstack/magnum-tempest-plugin openstack/manila openstack/manila-tempest-plugin openstack/masakari openstack/masakari-monitors openstack/mistral openstack/mistral-tempest-plugin openstack/monasca-api openstack/monasca-common openstack/monasca-events-api openstack/monasca-log-api openstack/monasca-tempest-plugin openstack/murano openstack/murano-tempest-plugin openstack/networking-generic-switch openstack/octavia openstack/octavia-tempest-plugin openstack/openstack-chef openstack/os-net-config openstack/os-win openstack/oswin-tempest-plugin openstack/paunch openstack/project-config openstack/puppet-pacemaker openstack/puppet-tripleo openstack/python-designateclient openstack/python-ironicclient openstack/python-saharaclient openstack/python-tripleoclient openstack/python-troveclient openstack/sahara openstack/sahara-tests openstack/senlin openstack/senlin-tempest-plugin openstack/solum openstack/solum-tempest-plugin openstack/telemetry-tempest-plugin openstack/tenks openstack/tripleo-ci openstack/tripleo-ci-health-queries openstack/tripleo-common openstack/tripleo-heat-templates openstack/tripleo-quickstart openstack/tripleo-quickstart-extras openstack/tripleo-upgrade openstack/trove openstack/trove-tempest-plugin openstack/vitrage openstack/vitrage-tempest-plugin openstack/watcher openstack/watcher-tempest-plugin openstack/zaqar openstack/zaqar-tempest-plugin openstack/zun openstack/zun-tempest-plugin windmill/windmill windmill/windmill-backup x/neutron-classifier x/vmware-nsx I'll go ahead and push changes to windmill/* and x/* as those are leftovers from splitting things up into tenants and haven't ended up in their own tenants yet. But it would be great if OpenStack can work on cleaning up this deprecated syntax in the OpenStack repos. I've attached a file with a listing that includes more details for each repo (branches and specific config files) to make it easier for people to find where the old syntax is located so that it can be replaced with the new syntax.

[all] Dynamic Zuul results table in Gerrit 3
by Radosław Piliszek 04 Aug '22

04 Aug '22

Hello Fellow OpenStack and OpenDev Folks! TL;DR click on [3] and enjoy. I am starting this thread to not hijack the discussion happening on [1]. First of all, I would like to thank gibi (Balazs Gibizer) for hacking a way to get the place to render the table in the first place (pun intended). I have been a long-time-now user of [2]. I have improved and customised it for myself but never really got to share back the changes I made. The new Gerrit obviously broke the whole script so it was of no use to share at that particular state. However, inspired by gibi's work, I decided to finally sit down and fix it to work with Gerrit 3 and here it comes: [3]. Works well on Chrome with Tampermonkey. Not tested others. I hope you will enjoy this little helper (I do). I know the script looks super fugly but it generally boils down to a mix of styles of 3 people and Gerrit having funky UI rendering. Finally, I'd also like to thank hrw (Marcin Juszkiewicz) for linking me to the original Michel's script in 2019. [1] http://lists.openstack.org/pipermail/openstack-discuss/2020-November/019051… [2] https://opendev.org/x/coats/src/commit/444c95738677593dcfed0cfd9667d4c4f0d5… [3] https://gist.github.com/yoctozepto/7ea1271c299d143388b7c1b1802ee75e Kind regards, -yoctozepto

Nova not updating to new size of an extended in-use / attached cinder volume (Ceph RBD) to guest
by Christian Rohmann 28 Jun '22

28 Jun '22

Hello Openstack-Discuss, after some digging I found out that cinder learned to resize attached (in-use) volumes quite a while ago with the introduction of the initial "extend 'in-use' volume" feature: https://review.opendev.org/c/openstack/cinder/+/454287/ The support was then extended to also cover Ceph RBD backed volumes with: https://review.opendev.org/c/openstack/nova/+/613039/ Since this is only about the cinder part, I was wondering if nova would ever find out and would actively rescan the device / volume and quintessentially present an increased new size to the guest. Apparently this is where a certain volume-extended event comes into play: https://review.opendev.org/c/openstack/nova/+/454322/ that is to be emitted by cinder when a volume had been extened. I then went head and tried this with the openstack cli (as Horizon does not seem to support / offer to resize in-use volumes. I run Openstack Train with Ceph RBD as storage. First I ran into an issue with the openstack cli (https://bugs.launchpad.net/cinder/+bug/1871759/comments/2 <https://bugs.launchpad.net/cinder/+bug/1871759/comments/2>) but using cinder extend $volumeid $newsize I was able to resize in-use volumes just fine. The only thing missing was the propagation to the guest. I played around with SCSI rescans, but that did not work, reboots also failed to do anyting in this regards. Stopping and starting the VM did work, but why having the capability to online-resize an attached volume when not being able to resize the guest volume as well? Apparently there seems to be an old and somewhat similar observation / bug with https://bugs.launchpad.net/nova/+bug/1369465 So I was simply wondering if this is expected to be working? Are there any special settings / options I need to set to enable this feature? Thanks and with kind regards Christian

by Taltavull Jean-François 26 Jun '22

Hi All, I get an http 403 error code when I try to get the bucket list with Ubuntu (Focal) S3 client (awscli). S3 api has been activated in radosgw config file and EC2 credentials have been created and put in S3 client config file. Otherwise, everything is working fine with OpenStack client. My deployment: - OSA 23.2.0 - OpenStack Wallaby - Ceph and Rados GW Octopus Has any of you already experienced this kind of behaviour ? Many thanks, Jean-Francois
