** Moving OpenDev's python-base/python-builder/uwsgi-base Images to Quay (clarkb 20250812)
 
*** The images have moved and we're no longer publishing to docker hub
 
*** https://lists.opendev.org/archives/list/service-announce@lists.opendev.org/thread/HO6Z66QIMDIDY7CCVAREDOPSYZYNKIT3/
 
*** I believe that all images within OpenDev that consume these base images have been updated to pull from the new location (including Gerrit)
 
*** If you find images that need updates please push a change and let us know.

*** The entire openafs and kerberos system has been upgraded to Noble except for afs02.dfw.openstack.org. Waiting on RW volume moves to complete before performing this last upgrade

*** Can probably spin up new backup servers alongside the old ones then migrate the old volumes off the old servers to the new ones and finally delete the old servers. Just need to double check borg version support matrix details and also what adding new backup servers will do to our cron job setups for backups.

*** Fungi identified a number of AFS mirror cleanups that can be performed once server upgrades are complete

*** Debian stretch, bullseye backports, and openeuler content has been cleaned up.
*** OpenEuler mirror content is no longer needed as we don't have any test images
+
*** Can we automate cleanups for reprepro content? In other words are the steps cheap enough during the noop case to run with our regular reprepro update script?
*** Debian stretch and bullseye backports are no longer needed as they are both old enough to have aged out
+
*** Additional volumes to look into cleanups for include ceph, docker, and puppetlabs package mirrors as well as our python wheel caches
*** For the reprepro content we should also look into automatically clearing content if the cost to do so is actually a noop when we haven't removed releases from the mirror list.
+
*** CentOS 9 Stream grows at a rate that requires regular quota bumps. Is there anything we can do about that?
 +
*** With these cleanups and server upgrades completed we can probably start to consider adding new mirrors again.

*** Mailman's data is now backed by a dedicated volume capable of many more IOPs than the root disk. Let us know if you see new occurrences of unexpected slowness.
*** Specifically the value is 2 on Standard (lists) and 40 on mirror and fio measures about a 20x differences in iops during randread testing to match

** Deleting ze11 (clarkb 20250923)
*** We will need to migrate the mailman3 installation off of the server disk and onto a cinder volume to improve the number of iops.
+
*** The ze11 zuul executor has been shutdown for some time due to network slowness cloning the nova repository.
 +
*** We have a 10 minute timeout for that clone, most nodes do it in ~4 minutes, but ze11 does it in about 12-13 minutes.
 +
*** This slowness may also impact job runtimes as well
 +
*** At this point 11 or even 10 executors is probably sufficient for our needs the simplest solution here may be to delete ze11 entirely (and ze12 if we find its existence confusing)

** Zuul Launcher Updates (clarkb 20250923)
 +
*** We've run into weirdness with rax flex clouds booting instances with two network interfaces if networks are configured via zuul-providers config. This does not occur when networks are configured via clouds.yaml instead. This will need debugging
 +
*** All existing nodepool nodes have been deleted out of all cloud regions except for rax-ord. There are a number of nodepool instances there in an ERROR state that we cannot delete ourselves.
 +
*** I have sent email to Rackspace asking them to clean those nodes up as I believe they do count against our quota.

*** We have also disabled rax-dfw as it started having API errors similar to what we saw in IAD and ORD previously. My email included questions about this situation too.

Upcoming Project Renames

(any additions should mention original->new full names and link to the corresponding project-config rename change in Gerrit) Changes should have their topic set to project-rename.

Previous meetings
