** Gerrit 3.11 Upgrade Planning (clarkb 20250401)
 
*** https://www.gerritcodereview.com/3.11.html
 
*** Please check this for any concerns with the way we use Gerrit.
 
*** New held nodes are now available.
 
*** There is discussion about replication and reindexing bugs in 3.11.4/3.12.1 that don't affect us yet due to being on 3.10. We should try to test these problems to see if they affect us.
 
**** Clarkb tested this with held notes on admittedly trivial test data sets but was unable to reproduce the problems
 
*** Shutting down Gerrit can race the indexing of new changes. If this happens we can have new changes created that are not indexed leading to multiple changes with the same changeid later. To mitigate this we can/should reindex changes on Gerrit startup.
 
*** Gerrit shutdown remain plagued by large h2 cache files. Seems removing our long timeout was not enough to prevent shutdowns timing out.
 
*** https://etherpad.opendev.org/p/gerrit-upgrade-3.11 Planning Document for the eventual Upgrade
 
*** Will need to select a date once we know more about the upgrade itself.
 
** Gerrit Spontaneous Shutdown During Summit (clarkb 20251028)
 
*** The Gerrit server was discovered to be in a shutdown state with no recorded errors
 
*** The Nova team indicates this could happen if the hypervisor is unable to allocate memory. The host would be shutdown and Nova would notice but not record an error
 
*** Its possible the underlying cause is something else; either way we need to work with Vexxhost to identify the source of the problem and mitigate it
 
*** Is someone willing to figure out how to file a ticket with Vexxhost? This was their suggested approach last time we had problems.
 
 
** Upgrading Old Servers (clarkb 20230627)

*** Next on the list are graphite and backup servers
*** 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.

*** backup03.ca-ymq-1.vexxhost.opendev.org has been launched and is being backed up too

** Deploying a Prometheus for Server Metrics (clarkb 20260331)
*** https://review.opendev.org/c/opendev/system-config/+/965334 Mirror trixie packages
+
*** https://review.opendev.org/c/opendev/system-config/+/980840
*** Rocky Linux didn't hit these mirror issues because we don't mirror any rocky linux releases. Debian expects mirror content for all releases.
+
*** This change and its child deploy prometheus with node exporter to collect server metrics
** Zuul Launcher Updates (clarkb 20250923)
+
*** These two changes simplify the setup and testing of prometheus and node exporter
*** Nodes can be from mixed providers again due to a bug when reassigning unassigned nodes.

**** https://review.opendev.org/c/zuul/zuul-jobs/+/994564 manage /etc/hosts with public IPs
*** https://review.opendev.org/c/zuul/zuul/+/965954 Fix assignment of unassigned nodes.
+
**** https://review.opendev.org/c/opendev/system-config/+/994565 Use public IPs in system-config-run jobs
** Moving OpenDev Synchronous Communication to Matrix (clarkb 20250520)
+
** Larger VM sizes for tests (corvus 20260618)
*** The spec (954826) has merged.
+
*** corvus has been testing python 3.14 with zuul; zuul unit tests now use slightly more than 8GB under 3.14
*** clarkb will start working on this as soon as time permits.
+
*** We have 16gb nodes, but in two clouds, rax-classic and vexxhost, they have fewer vcpus than their 8gb counterparts, so we need to use 32gb nodes to compensate
** Etherpad 2.5.2 Upgrade (clarkb 20250805)
+
*** Are we okay with this?  Alternatives?
*** https://github.com/ether/etherpad-lite/blob/v2.5.2/CHANGELOG.md
+
** Dealing with alien zuul config errors in the openstack tenant (frickler 20260617)
*** https://review.opendev.org/c/opendev/system-config/+/956593
+
*** Currently there are still 185 zuul config errors in the openstack tenant, despite my year-long struggle to get rid of them.
*** This fixes our css issues and clarkb believes we are ready to upgrade.
+
*** Most of these are from "alien" repos (74 airship, 29 starlingx) that I have no motivation to fix myself with my OpenStack hats on
** Gitea 1.25.0 Upgrade (clarkb 20251028)
+
*** Efforts to motivate these projects to clean up their errors themselves have mostly failed
*** https://review.opendev.org/c/opendev/system-config/+/965960 Upgrade Gitea to 1.25.0
+
*** I still believe that cleaning these up and being able to easily identify fresh errors is important for the healthyness of the CI setup as a whole
** Gitea Performance (clarkb 20251028)
+
*** One pretty strong action would be to move these repos into their own tenant(s) or a different shared one like opendev
*** https://review.opendev.org/c/opendev/system-config/+/964728 Don't allow direct backend access
+
*** I acknowledge that without further work this would break their CI setup, but I'm questioning now whether that impact would be worse than the impact the current situation has on my ability to maintain the OpenStack CI
**** Some performance issues seem related to crawlers hitting backends directly so they aren't balanced properly
+
*** Other ideas or opinions are welcome
**** Most recent issue was via traffic to the load balancer frontend so this won't fix everything
+
*** clarkb reached out to starlingx and airship about this
**** Means we'll have to take extra steps to test backends directly (ssh port forwards)
+
**** Airship indicated they would like to avoid the extra work involved in setting up a separate tenant
*** https://review.opendev.org/c/opendev/system-config/+/965420 Increase memcached cache size to mitigate effect of crawlers poisoning the cache
+
**** clarkb pointed out to them that they would need to fix their zuul config errors and be reachable via email or matrix at a bare minumum if we want to make that work.
** Raxflex DFW3 Disabled (clarkb 20251104)
+
**** https://lists.starlingx.io/archives/list/starlingx-discuss@lists.starlingx.io/thread/YQVACUR4OCX74ZULHAJ4AD44MHGY37YI/
*** We discovered the raxflex dfw3 mirror had afs cache errors. fs flushall appeared to get stuck and the kernel oopsed. After forcing a shutdown via openstack the server refuses to boot
+
** Gitea 1.26.4 Upgrade (clarkb 20260622)
*** We've asked dan_with what our next steps should be via IRC
+
*** https://review.opendev.org/c/opendev/system-config/+/994326 Upgrade Gitea to 1.26.4
*** Worst case we rebuild the mirror with a new cinder volume and replace the whole thing.
+
*** Its time to upgrade to the next Gitea bugfix release
 +
** Bump Anubis difficult to 5 (clarkb 20260630)
 +
*** There is some evidence that bots are regularly solving the Anubis challenge
 +
*** The challenges are slowing them down enough that services continue to be mostly responsive
 +
*** Should we increase the difficulty one level to slow them down even futher?
 +
*** This will impact regular users too which is likely the primary consideration we should make.
 +
*** https://review.opendev.org/c/opendev/system-config/+/995096
 +
** Planning Gerrit Project Renames (clarkb 20260622)
 +
*** We have a request to rename x/cursive to openstack/cursive
 +
*** Any concern with project ownership doing that? The current group membership includes people from Johns Hopkins University and OpenStack Barbican
