---+!! Week of 240527 %TOC% ---++ WLCG Operations Call details * The connection details for remote participation are provided on this [[https://indico.cern.ch/event/1188295/][agenda page]]. ---++ General Information * The purpose of the meeting is: * to report significant operational issues (i.e. issues which can or did degrade experiment or site operations) which are ongoing or were resolved after the previous meeting; * to announce or schedule interventions at Tier-1 sites; * to inform about recent or upcoming changes in the experiment activities or systems having a visible impact on sites; * to provide important news about the middleware; * to communicate any other information considered interesting for WLCG operations. * The meeting should run from 15:00 Geneva time until 15:20, exceptionally to 15:30. * The SCOD rota for the next few weeks is at ScodRota * Whenever a particular topic needs to be discussed at the operations meeting requiring information from sites or experiments, it is highly recommended to announce it by email to the =wlcg-scod= list (at =cern.ch=) to allow the SCOD to make sure that the relevant parties have the time to collect the required information, or invite the right people at the meeting. ---++ Best practices for scheduled downtimes * [[BestPracticesForSchedDT][Best practices for scheduled downtimes]] ---++ Monday Attendance: * local: - * remote: Andrew (TRIUMF), Borja (Chair, Monitoring), Christoph (CMS), Carmen (CNAF), Federico (LHCB), Henryk (NCBJ), Julia (WLCG), Jens (NDGF), Onno (NL-T1), Panos (CMS, WLCG), Steve (Computing), Timo (ATLAS), Xavier (KIT) Experiments round table: * ATLAS [[AtlasComputing.ADCOperationsWeeklySummaries2024][reports]] ([[AtlasComputing.ADCOperationsWeeklySummaries2024?raw=on][raw view]]) - * NTR * CMS [[CMS.FacOps_WLCGdailyreports][reports]] ([[CMS.FacOps_WLCGdailyreports?raw=on][raw view]]) - * Good resource usage and rather quiet operations * Campaign to phase out deprecated protocols is progressing * ALICE * NTR * LHCb [[LHCb.ProductionOperationsWLCGdailyReports][reports]] ([[LHCb.ProductionOperationsWLCGdailyReports?raw=on][raw view]]) - * New ETF test profile deployed. Few minor issues being addressed (few sites contacted) Sites / Services round table: * BNL: NTR * CNAF: NTR * EGI: NC * FNAL: NC * !IN2P3: Site will be in downtime on June 25th for quarterly maintenance. Details will be communicated a week before. * JINR: NC * KISTI: NC * KIT: Related to GGUS:166873 (reported by LHCb, "ETF tests are failing for almost all GRIDKA's CEs"), we only have 1 CE left that supports x509-based GSI. * NCBJ: NTR * NDGF: dCache upgrade this week. Should solve a long outstanding issue with lost transfer markers for 3d party transfers and will be a required version to support the bulk service. * NL-T1: NTR * NRC-KI: NC * OSG: NC * PIC: NC * !RAL: RAL will be migrating the CVMFS Stratum-1 to a new infrastructure and architecture on the 28/5/24 (GOCDB:35426). The process involves a change in DNS, therefore may take a day or so to be implemented. If everything goes well, the whole migration should be fully transparent. However, as we are migrating to a brand-new architecture, scaling issues may arise on production that have not been noticed during testing. In that instance, please do not hesitate to contact the RAL Tier-1 Production Team. * TRIUMF: NTR * CERN computing services: HammerCloud will be update Tuesday 18th June [[https://cern.service-now.com/service-portal?id=outage&n=OTG0150094][OTG0150094]] * CERN storage services: NC * CERN databases: NC * GGUS: * A new release is planned for Wed this week * [[https://ggus.eu/?mode=release_notes][Release notes]] * A [[https://goc.egi.eu/portal/index.php?Page_Type=Downtime&id=34847][downtime]] has been scheduled from 06:00 to 08:00 UTC * Test alarms will be submitted as needed * Monitoring: NTR * Middleware: NTR * Networks: NC * Security: NC AOB:
