DDM monitoring

Logbook

  • In LYONDISK, files older than 24 hours are deleted (not LFC entries)
  • 3 October
    • dcache for SC4 tests back in operation
    • Start transfer from LYONDISK to T2s (try to follow online)
    • Since dataset are destroyed at CERN after 24 hours, only datasets younger than 12 hours are transfered to T2s.
    • Bad transfer rate to GRIF (FTS never finish for the 3 ATLAS sites)
    • SE in CPPM is full
    • 20-30 MB/s rate for 4 sites
  • 2 October :
    • Problems with dcache in Lyon
  • 30 September-1 October :
    • T0-T1 transfer chaotic due to problems for DDM to get FTS messages (use CERN FTS server) (then transfers are killed).
  • Status after one week :
    • Transfer ran smoothly with the usual problem of LFC access speed
    • No T1-T2 transfer

  • 24 September: Upgrade of DDM software. VOBOX activity much lower.
