• ATLAS
  • Have applied a patch which forces deep=True for all list-dataset-replicas requests.
    • This might remove the necessity for the collection_replicas table.
    • Initial results show poor performance on the database; however, it could be due to other activity.
    • Will continue to monitor and report in the next meeting.
    • This effort is related to the work on the Abacus daemon.
• CMS
  • Follow-up on Kubernetes nodes becoming unstable:
    • Overflow of logs (related to CERN and MONIT, not Rucio).

  • Poor deletion performance when using too many threads:
    • Improved by applying some change on the PostgreSQL partitioning.
• Fermilab/ICARUS/Rubin

    • Unexpected authentication errors (reported on Mattermost).
• DUNE
  • Work for WLCG Data Challenge.
  • Had to switch from regular to greedy deletion:
    • Appearance of dark data. Interested in the CMS-style consistency enforcement.
