Experiments round table:

  • ATLAS reports (raw view) -
    • T0
      • GGUS:92166 (transfers to CERN failing with "Error with credential") still open and creating troubles. The issue has been open at the beginning of march, has been intermittent, never really understood AFAIK. CMS did observe the same issue at some point. ATLAS updated the ticket today with the most recent failures. Please investigate.
        • Maarten: the expert was overloaded with other urgent matters and then away on holidays; will follow up offline
        • Simone: the matter has not been critical because the transfers usually make it OK later, but the monitoring very often has a lot of red, which makes other issues difficult to spot
    • T1s
      • Issue with file staging at CNAF. GGUS:93165 has been submitted.

  • CMS reports (raw view) -
    • LHC / CMS
      • Rereconstruction of 2012 data in the tails, load at the T1 sites small

      • We are beginning to treat CERN more as a T1 in terms of transfers, processing
    • Tier-1:
      • IN2P3 Hammercloud and SAM test failures over weekend seems solved but (as of last night) GGUS tickets still open
