      CMS Operations Report 5m
      Speaker: Katy Ellis (Science and Technology Facilities Council STFC (GB))

      Katy is at CERN this week for CMS O&C week. Two talks on tape activities and one on UK resources in HL-LHC.

      Nothing new to report. I'm finding out how to deal with the /unmerged/ data that isn't being deleted, as discovered last week.

      News:

      • First 2026 data is expected this week.
      • LHCb is investigating cgroup usage for limiting job resource consumption. Can we set it up at RAL?
        • We have a preprod ETF test for this (see here).
      • Writable WN gateway deployment delayed due to configuration issues.


      Operational issues:

      • User job failures last week
        • Buggy xrootd version, user informed
      • Failed transfers from CBPF to RAL yesterday
        • CBPF DNS issues (not our fault).
