Description
grid-operations-meeting@cern.ch
Weekly OSG, EGEE, WLCG infrastructure coordination meeting.
We discuss the weekly running of the production grid infrastructure based on weekly reports from the attendees. The reported issues are discussed, assigned to the relevant teams, followed up and escalated when needed. The meeting is also the forum for the sites to get a summary of the weekly WLCG activities and plans
Attendees:
  • OSG operations team
  • EGEE operations team
  • EGEE ROC managers
  • WLCG coordination representatives
  • WLCG Tier-1 representatives
  • other site representatives (optional)
  • GGUS representatives
  • VO representatives

        • <big> Grid-Operator-on-Duty handover </big>
          From: Russia / CERN
          To: SouthEast Europe / France

          Issues from Russian ROC::
          1. There are nodes which are not registered or have switch off the monitoring in the GOC DB, but are tested by SAM:
            • prod-bdii.cern.ch
            • se-0-fzk.gridka.de
            • e5grid08.physik.uni-dortmund.de
          2. The site RO-01-ICI (SEE ROC) has a wrong tuned spam filter, so it can not receive COD's e-mails. Ticket #29126 was opened about.
          Issues from CERN ROC::
          1. One site to be raised at operation meeting for suspension:
            VGTU-gLite - Northern ROC.

        • <big> PPS Report & Issues </big>
          PPS reports were not received from these ROCs:
          AP, CE, IT, SEE, SWE
          Issues from EGEE ROCs:
          1. Nothing reported

          Release News:
          1. No release to PPS is scheduled for this week.
          Calls for volunteers:
          1. PPS has started supporting a new VO, blaubert, aimed to the study of financial derivatives in a market based on grid resource trade.
            All PPS sites are kindly invited to start supporting the new VO with resources, in the idea that the more real usage of our system we have, the more effective we are in spotting potential issues with the release.
            The VO is hosted at CNAF and all parameters needed to configure your site can be retrieved directly on the voms server
            https://cert-voms-01.cnaf.infn.it:8443/voms/blaubert/ Many thanks in advance to all adhering sites
          2. In the PPS we’re helping the ATLAS and CMS VOs to try out a solution for allowing VOs to set the relative priorities of their jobs at a site. We’re looking for 1 more volunteer site in PPS, not necessarily experienced with the set-up of this feature. Joining this effort won’t take much work and won’t be for long but it will be relatively high profile and would bring the site "on the spot" with the VOs
            We need to find another site quickly, so a quick response would be very helpful.
        • <big> EGEE issues coming from ROC reports </big>
          1. (ROC France): CEs disappeared from SAM DB. Judit has opened a Savannah bug (https://savannah.cern.ch/bugs/index.php?31229).
          2. (ROC France): IN2P3-CC on 9th of Nov., SiteBDII appears in grey in Gridview, but no downtime and site is OK. It is impacting the overall availability.
            (https://gridview.cern.ch/GRIDVIEW/same_graphs.php?GraphName=sBDII&Information=SiteDetail&DefVO=15&TestVO=-1&DurationOption=hourly&LComponent=-2&NodeID=-1&TestID=-1&StartDay=9&StartMonth=11&StartYear=2007&EndDay=19&EndMonth=11&EndYear=2007&LTier1Site=28&RelOrAvail=Availability&ContAvailFlag=ON&SiteFullName=0

            Other French have seen the same behaviour. What is grey color for?
