** Improving OpenDev's CD throughput (clarkb 20211116)
+
** Upgrading Old Servers (clarkb 20230627)
*** We can run many of our jobs in parallel in all of our CD pipelines. But this requires we properly document/address dependencies
+
*** https://etherpad.opendev.org/p/opendev-bionic-server-upgrades
**** Need to understand our job dependencies and properly note them in Zuul config or address them by combining jobs.
+
*** https://etherpad.opendev.org/p/opendev-focal-server-upgrades
***** Example 1: Combine service-gitea-lb and service-gitea jobs.
+
*** https://review.opendev.org/q/topic:jitsi_meet-jammy-update
***** Example 2: Combine letsencrypt and nameserver jobs
+
*** Started looking at the wiki there are rough notes at: https://etherpad.opendev.org/p/opendev-bionic-server-upgrades#L58
***** Example 3: Have all jobs with webserver config express a dependency on the letsencrypt job
+
** MariaDB Upgrades (clarkb 20240220)
**** Suggest we document the known job dependencies in a human readable format, then encode this into zuul, then we can switch to parallel runs.
+
*** Relying on the container image MARIADB_AUTO_UPGRADE flag
**** https://review.opendev.org/c/opendev/system-config/+/807672
+
*** Everything but Gerrit is done now. When do we think we want to do Gerrit?
***** should list dependencies for all jobs
+
** AFS Mirror cleanups (clarkb 20240220)
***** zuul doesn't trigger on this?  not sure on best approach to make it mergable
+
*** Ubuntu Xenial cleanups are starting to show up under topic:drop-ubuntu-xenial
**** https://review.opendev.org/c/opendev/base-jobs/+/807807
+
*** Can followup with webserver log processing to determine which other mirrors may be dead.
***** currently every executor adds keys for bridge, then logs in and clones system-config before running playbooks
+
** Building Ubuntu Noble Nodes (clarkb 20240416)
***** this change makes split jobs to do this.  however, production remains the same as both are called.
+
*** Next step is to add Noble to our mirrors
**** https://review.opendev.org/c/opendev/system-config/+/807808
+
** Gerrit 3.9 Upgrade Planning (clarkb 20240423)
***** this is a follow-on that adds a base job to clone system-config, and stops the other production jobs re-cloning.
+
*** Upgrade prep notes are going in https://etherpad.opendev.org/p/gerrit-upgrade-3.9
***** this job must run first, but then all other jobs can run in parallel, as they are all in the same buildset and using the same "view" of system-config for that particular run
+
*** https://www.gerritcodereview.com/3.9.html Release Notes
** Gerrit Account cleanups (clarkb 20211116)
+
*** https://review.opendev.org/c/opendev/system-config/+/918333 Need updated and promoted 3.9 image before doing more testing.
*** 33 conflicts remain. Clarkb has written notes on proposed plans for each user in the comments of review02:~clarkb/gerrit_user_cleanups/audit-results-annotated.yaml
+
*** Downgrade is possible with an offline reindex using the old war.
** Zuul multi scheduler setup (clarkb 20211116)
+
*** Things to think about:
*** Zuul is currently running with two schedulers (zuul01.o.o and zuul02.o.o with zuul02.o.o being "primary")
+
**** Do we want to enable diff3 diffs on merge changes?
*** Did first rolling restart of schedulers over the weekend.
+
**** Change topic limit seems to only apply to open changes. Being over the limit doesn't seem to impact the upgrade process
*** Zuul-web should return consistent results now as it talk to ZooKeeper directly.
+
**** https://gerrit-review.googlesource.com/c/gerrit/+/424404 Upstream change to have release war build target without webfonts
** User management on our systems (clarkb 20211116)
+
**** There is a new batched ref updated event that collects multiple ref updated events in a single event. This is disabled by default, but could one day impact zuul. Work sorting out likely.
*** Be explicit about uid/gid ranges: https://review.opendev.org/c/opendev/system-config/+/816869/
+
*** Server could stand to be upgraded as well but I think it is probably best to decouple these concerns.
**** 0-999 system, 1000-1999 unallocated, 2000-2999 for infra-root users, 3000-9999 host level users, 10k - 64k container users that need uids on the host as well for bind mounts.
+
** Wiki SSL Cert Renewal (clarkb 20240423)
*** Give gerritbot and matrix-gerritbot a shared user: https://review.opendev.org/c/opendev/system-config/+/816769/
+
*** Clarkb will renew Friday ish (May 10)
*** Eventually convert mariadb container's from uid 999 to something that makes more sense on the system.
 
** Caching openstack/openstack on our DIB images (clarkb 20211116)
 
*** There are semi frequent errors when updating the DIB cache for openstack/openstack
 
*** Seems related to verifying or updating submodule content.
 
*** One theory is that we replicate openstack/openstack's submodule updates before we push the new refs to the other repos. Then if DIB fetches in that window of time it is an error.
 
*** Should we simply stop caching this repo entirely? It isn't really used for much.
