December 2013 Reports

To the main

19th December 2013 (Thursday)

  • reprocessing of ProtonIon collisions in full swing at CERN/GRIDKA
  • At other sites main activities are simulation & user jobs
  • T0:
    • Impressive staging performance (140TB/24h), stage in for reprocessing is finished
  • T1:
    • GRIDKA: problems with file access via xroot, switched back to dcap for the time being.

  • reprocessing of ProtonIon collisions started last week at GRIDKA/CERN,
  • At other sites main activities are simulation & user jobs
  • T0:

  • T1:
    • FZK: Pilot problems, solved (GGUS:99725)
    • FZK: Issue with tape system over the week-end, now resolved, staging throughput increasing.

  • Other:
    • Problems with FTS3 transfers to CBPF which is running slc6.5. This linux version produces SSL3 handshake problems (GGUS:99398)

12th December 2013 (Thursday)

  • Main activities is Simulation at all Sites.
  • Some DIRAC monitoring down due to work on re-indexing accounting tables.
  • T0:
    • srm problem solved on Tuesday (stuck request - GGUS:99614)

  • T1:
    • IN2P3 : Problem with nagios probe (GGUS:99420) seems to have gone away (for now). Not sure we understand why.
    • GridKa : Possibly flickering jobSubmit to all CEs
    • GridKa : Also possible problem with batch system. Job submission to GridKa currently stopped. Local contact (Alexey) and admins informed.

5th December 2013 (Thursday)

  • Main activities is Simulation at all Sites.
  • T0:
    • EOS name space migration to .../lhcb/grid/lhcb/... completed making possible to migrate user files from Castor to EOS storage
  • T1:
    • Disk failure at PIC (resolved) resulting in temporary Input Data resolution problems
    • GRIDKA: xrootd configuration problems, using dcap access for the moment
    • GRIDKA: currently all pilots are failing with direct submission to the CREAM CE: https://ggus.eu/ws/ticket_info.php?ticket=99491
    • CNAF storage at srm://storm-fe-lhcb.cr.cnaf.infn.it/... is in unscheduled shutdown

2nd December 2013 (Monday)

  • Main activities is Simulation at all Sites.
  • T0:

  • T1:
    • Network interruption at PIC on the weekend
    • GRIDKA: problems with file downloading presumably due to failure getting metadata from the local SRM
