Experiments round table:

  • CMS reports (raw view) -
    • Still analysis running full steam. Production activity level low due to lack of demand.
    • No outstanding GGUS
    • CERN's AFS Grid UI broke on friday INC:0632606. Disrupted CMS production submission and Hammer Cloud testing, which pick there the up-to-date Certs and CRL lists. Resolution involved reboot of all CMS machines, still working on recovery for HammerCloud, no tests sent yet.
      • Steve: the intervention was done to make it easier to find out which clients are still using the AFS UI; it was expected to be transparent
