      LHCb Operations Report
      Speaker: Alexander Rogovskiy (Rutherford Appleton Laboratory)

      Quiet week for LHCb, no noticeable issues at RAL. There are many buggy MC productions in the queue this week, as a result we (among other sites) have higher failure rate. Not our fault.

      ALICE Operations Report
      Speaker: Alexander Rogovskiy (Rutherford Appleton Laboratory)
      • ALICE agreed to remove excess data from ECHO
        • May take some time
      • They are still not getting storage accounting from ECHO
        • The main reason seems to be negative free space, so should be fixed once the excess data is removed
        • Another issue is that redirectors are not accessible via IPv6 from non-LHCOPN 
          • Should be automatically fixed once the proxmox migration is done
        • We were also asked to install mlsensor service on the ALICE gateways and redirectors

      LSST Operations Report
      Speakers: Thomas Birkett, Timothy Noble (Science and Technology Facilities Council STFC (GB))
      • Data movement test between RAL and LANCS - moving data to RAL now
      • Some job failures over the week due to fatfingering of packages to install in LSST stack (_gdal-config vs gdal_config) - now fixed and jobs running again
      • Some data movement to RAL but seems to have stalled
      • Small amount of date moved from RAL to LANCS
