WLCG Operations Call details

• The connection details for remote participation are provided on this 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.

• CNAF:
• EGI:
• FNAL:
  • Migration to Alma9 progressing well. Nothing major to report otherwise.
  • GGUS paging still broken. Internal discussions ongoing whether to focus effort on getting GGUS fixed or to integrate with the new GGUS replacement that's coming soon.

  • Decommissioned SRM support for LHCb as of last Friday
  • Removed protocol specific CNAMEs for dCache endpoints from DNS (context ATLAS GGUS:166267, LHCb GGUS:166268, Belle GGUS:166269)
  • Disk cache of HPSS ran full, because mounting of tape drives broke over the weekend. Therefor ATLAS in particular might experience some delay in their current staging campaign.
  • First compute node has been upgraded to RHEL-8 and we'll get in contact with CMS and LHCb representatives to get some tests for it.
  • CE-4 has been upgraded to RHEL-8 last week, next up is CE-3 (GOCDB:35372)
