  • Main activity are MC productions
  • Plan to start another incremental stripping campaign in mid Sept -> heavy stress for tape systems
  • Reminder for T1 sites to implement tape families for the future (see also https://twiki.cern.ch/twiki/bin/view/LHCb/NameSpace)

26th August 2013 (Monday)

  • Only MC productions ongoing, including using BOINC prototype
  • T0:
    • switched back to FTS2 transfer system, b/c of issue with accounting of file transfer starting date, and wrongly accounted within DIRAC, needs to be fixed on both sides.
    • CE301, CE302 new CEs show wrong OS information in the BDII
    • removal campaign for large number of histograms on CASTOR Disk was launched
  • T1:
    • NTR
