  • local: AndreaS, Steve, Maarten, Ken/CMS, Eddie, Massimo
  • remote: Alexander/NL-T1, Michael/BNL, Peter/ATLAS, Xavier/KIT, Saverio/CNAF, Boris/NDGF, Nadia/IN2P3-CC, Kyle/OSG, Tiju/RAL, Lisa/FNAL, Wei-Jen/ASGC, Sang-Un/KISTI

Experiments round table:

  • ATLAS reports (raw view) -
    • T0/Central services
      • NTR
    • T1
      • BNL file recovery progressing
      • RAL disk server problem. All files successfully recovered.
      • SARA Transfer errors (Failed to contact on remote SRM) GGUS:95911. Fixed

  • CMS reports (raw view) -
    • Continuing 2011 legacy rereco activity and some Upgrade MC generation, everything pretty quiet
    • From last week, RAL GGUS:95825 was declared a Castor bug.
    • Castor T1TRANSFER service was degraded again over the weekend. But still not a real problem; probably deserves some discussion with CMS as to what the shifter instructions should be. [Massimo: the problem is related to an increasing mismatch between the CASTOR tuning and the evolution of the CMS usage patterns; it would be good to have a meeting where to discuss these issues.]
    • GGUS:95887 to T1_FR_IN2P3 is about file read errors. Ticket came Friday, site started working on it today.
    • Wigner T-Systems 100 Gbit link down for several hours over the weekend. [Maarten: Wigner vs. CERN computer centre should be transparent: don't mind too much about SLS errors unless they have a direct effect. Ken: will check if there was any impact on CMS.]

  • ALICE -
    • CERN: all CERN CEs started refusing proxies of ALICE and other VOs around 18:20 Sunday evening; fixed around 09:15 Monday morning (TEAM ticket GGUS:95914) [Maarten: the problem was most likely related to a bad ARGUS configuration and it was solved by Ulrich but there are no details in the ticket.]

Sites / Services round table:

  • ASGC: ntr
  • BNL: ntr
  • CNAF: ntr
  • FNAL: ntr
  • IN2P3-CC: ntr
  • KIT: ntr, just a reminder of a downtime starting tomorrow by closing the queues to update the SE for LHCb
  • KISTI: ntr
  • NDGF: SRM downtime tomorrow from 7 to 9, to update dCache and install a new host certificate; some disk pools will also be updated.
  • NL-T1: ntr
  • RAL: tomorrow, "at risk" intervention to the site firewall, followed from 10 to 16 by a CASTOR upgrade for LHCb and CMS
  • OSG: ntr
  • CERN batch and grid services: ntr
  • CERN storage services: just upgraded SRM for all experiments (apart from LHCb, which was upgraded last week). The upgrade should have been transparent.
  • Dashboards: ntr

Experiments round table:

  • ATLAS reports (raw view) -
    • T0/Central services
      • ATLR database outage yesterday evening, looks fine now INCIDENT
    • T1
      • All except cern and bnl PRODDISK endpoints have been removed from ATLAS data management
      • FZK and DE T2 sites now configured to use FTS3

  • CMS reports (raw view) -
    • T1 disk/tape separation is getting done (RAL first site) and we are starting to nail out details of how to send users analysis jobs to T1's using pilots
    • Continuing 2011 legacy rereco activity and some Upgrade MC generation, everything pretty quiet
    • GGUS:95887 to T1_FR_IN2P3 about file read error solved by reconfiguring dCache there (more time to dCache movers). Details not understood.
    • GGUS:96102: file read error at T1_UK_RAL . Site now looking into this.
    • nothing else worth mentioning

  • ALICE -
    • NTR
