  • ROC_IT is asking ROC_CERN to chase the Beijing site (To be done by Diana; GGUS:40700).
  • ROC_Russia suspended the site requested by ROC_FR (GGUS:40521).
  • ROC_FR is asking Nick to chase the suspension of site ITPA-LCG2 (To be done by ROC_NE; GGUS:42015).

PPS Reports

  • CERN has SLC5 experimental setup accessible via CE110 in PPS BDII.
  • PPS gLite U38 has patches scheduled for Prod (U35) on Thursday. New version of VOMS & various other stuff.

EGEE Items From ROC Reports

  • ROC_SEE: serious deployment problem for 64-bit WNs, missing x86_64 RPMs and mix-up of executables and libraries for 32-bit and 64-bit architectures (GGUS:43216). Due to this problem we had to take manual steps to resolve the issue and were failing SAM tests for several days, which will affect our availability. The error message was very misleading. Andreas said that a proper solution will take a while (requires repackaging). BUG:40734 and BUG:33616 suggest to install the 64-bit RPM over the 32-bit one. Data Management and VDT are independently working on fixes.
  • ROC_SWE: IFIC-LCG2 site still not showing sBDII test results GGUS:43353. John will investigate [problem fixed by David Collados the same day, and availability recalculated for impacted sites].

WLCG issues coming from ROC reports

* RAL batch farm occupancy by LHC VOs is down. Other Tier1s/ROCs should send feedback to RAL/Nick. Alessandro said that ATLAS had reduced Grid activity due to internal reasons and the accelerator stoppage. GridKa don’t have huge occupancy. Roberto LHCb objects: there are periods where activity to Tier1 is light. Derek: relative occupancy per Tier1 is problem, not total activity. RAL just wants to check that they’re not being left out.

Upcoming WLCG Service Interventions
