• ATLAS
  • Issue with Throttler
    • Requests remain in WAITING state forever --> #4979
    • Way to manually run the throttler to unblock it
  • Heartbeats
    • With frequent Kubernetes pod-restarts, often outdated heartbeats are found
      • Ideally pod-shutdown should issue a heartbeat-removal as well, but doesn't seem to happen #4988
• CMS
  • CTA multihop transfer
    • More space on EOS to leave space for multihop
      • --> More data (and thus Jobs) sent to EOS
      • Possibly based on freespace weights on rules
        • Freespace weight could be adapted
          • ATLAS investigating if using relative freespace weights instead of absolute could be beneficial
• Fermilab/DUNE/ICARUS/RUBIN
  • Staging failures on tape system
  • Number of files in RUBIN
    • Large number of files, might be an issue for transfers/tapes
• Belle II
  • mod_gridsite issue
    • Writes into /var/cache/gridsite
      • Many files written there
  • More work on metadata
• DUNE
  • Work on policy packages for the client
  • After that going back to leightweight rucio clients
• Multi-VO
  • Conveyor submitter/poller 
    • After discussion on slack it works much better now
    • Radu and Tim implemented a fix which should be able to select the right certficiate for the right VO

  • DAC21 (Data and Analysis Challenge 21) next week
  • Currently two issues:
    • Hermes ​​increases memory consumption until it crashes?
      • Kubernetes metrics vs prometheus memory consumption does not add up?
    • Reaper greedy deletion
      • Found small unrelated bug which is fixed in helm-chart
      • LSST usecases --> want to reach 60k deletion / h
