Logbook

• In LYONDISK, files older than xxx hours are deleted (not LFC entries)
• 24 September: Upgrade of DDM software. VOBOX activity much lower.
• First week :
  • Transfer ran smoothly with the usual problem of LFC access speed
  • No T1-T2 transfer

• 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).
• 2 October :
  • Problems with dcache in Lyon
• 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.
