The ~lsstsw home dir on lsst-dev was at ~1TiB and presumably was at the quota limit. I was able to free up ~350GiB by removing an old copy of installed eups products. This got the release past the build/publish steps but failed tagging the git repos due to the eups distrib tag and versiondb being out of sync. Rerunning the pipeline got past this step. My assumption is this was due to s3's eventual consistency. Newly created objects tend to be visible immediately but it can occasionally take minutes for the new version of a replaced object to become visible. This can likely be worked around in the future by adding a sleep step into the release pipeline.
The eups distrib, git tag, and tarballs have been published but the pipeline failed building the jupyterlab demo.
