Monday

Attendance:

  • local: Stefan (SCOD), Maarten (ALICE), Alessandro (ATLAS), Michail (LHCb), Tsung-Hsun Wu (ASGC), Zbigniew (Databases), Ignazio (Grid Services),
  • remote: Lisa (FNAL), Sang Un (KISTI), Ulf (NDGF), Tiju (RAL), Onno (NL-T1), Antonio (CNAF), Rolf (IN2P3), Dimitri (KIT), Pepe (PIC), Kyle (OSG), Michael (BNL)

Experiments round table:

  • ATLAS
    • CentralService/T0/T1s
      • FZK-LCG2 GGUS:110157 . ATLAS experts and FZK experts are investigating together. The problem has to be studied more. For the future to be discussed with FTS3.
    • Daily Activity overview
      • Fix Prodsys1 unfinished oldest than 1 month tasks (ADCSUPPORT-4049): 42% completed. The 465 tasks remaining are pile (117), reco (43), merge (135), evgen (108), simul (62).
      • Fix Prodsys1 tasks almost finished with few jobs missing (ADCSUPPORT-4048): 10% completed . The 135 tasks remaining are pile (54), reco (5), merge (47) and simul (29).
      • Babysitting of the 8 TeV derivation production tasks in Prodsys2 (ADCSUPPORT-4045): 97% completed. The number of tasks has been reduced from 465 tasks (12 november) to 15 tasks.
      • DQ2 clients testing: Doug reported various issues. 2 blockers, one on container, one on dq2-put which requires lumiblock. This second already fixed in next rel cand, the first reported only sunday afternoon. Dq2 ls now mix the output with scope (if in rucio) or without scope. We write it in the FAQ.

  • CMS
    • NR

  • ALICE -
    • NTR

  • LHCb
    • MC and user jobs. "Legacy Run1 stripping campaign", new schedule for stripping21 is on Wed (the earliest)
    • T0: NTR
    • T1: Replication of full.dst is over in all sites except GridKa due to slow staging progress

Sites / Services round table:

  • ASGC: NTR
  • BNL: NTR
  • CNAF: NTR
  • FNAL: NTR
  • GridPP: NR
  • IN2P3: NTR
  • JINR: NR
  • KISTI: Issue with mailing list ticket GGUS:109886 is fixed (reported in last meeting), ALARM tickets will delivered correctly now
  • KIT: Working on fixing the staging problems discovered during the week-end, report to be provided later
  • NDGF: NTR
  • NL-T1: NTR
  • OSG: NTR
  • PIC: NTR
  • RAL: NTR
  • RRC-KI: NR
  • TRIUMF: NR

  • CERN batch and grid services: Problem with one squid server which was stuck, problem on lxplus, fixed now
  • CERN storage services: NR
  • Databases: Today migration of golden gate cluster. LHCb / ATLAS will be partially unavailable, each for approx 20 min downtime, migration will start after this meeting. Tomorrow rolling patches for ATLAS/CMS integration databases. Wednesday switch over active dataguard service (ADCR DB) for ATLAS to new hardware, to be transparent.
  • GGUS: NR
  • Grid Monitoring: NR
  • MW Officer: It was found that the new Red Hat kernel 2.6.32-504 that comes with RHEL6.6 and as a security patch for older RHEL6 installations has a bug wrt. fuse. Due to the bug, cvmfs clients that are exported via NFS immediately provoke a kernel panic. The problem is not cvmfs specific but all fuse modules that are exported via NFS are affected. Site's that use the NFS exported cvmfs client must not update to this kernel. The common cvmfs deployment mode as a fuse module on the worker nodes seems not to be affected.
