Discussion

  • AI (Brian, Edgar): Last Friday, Edgar discovered an XCache configuration bug and he will submit a PR.
  • UCSD XRootD update: Diego and Edgar have worked getting this together and they've got it working. Next step is to transition to the OSG XRootD standalone packaging using the documentation. Diego has written a few notes on what was difficult and will pass that along.

Support Update

  • Brown (Marian): Still working on getting Phedex working. Marian will coordinate a live support session with the Brown admins and a Phedex expert to finally get this working.
  • Central Collector, ITB CE (BrianL): clients hang when querying collectors. Nothing show up in the logs but telnet works. Edgar suggested that it may be an issue with dual-stacked clients.
  • UPR (BrianL): some confusion when updating HTCondor (to 8.8 and 8.9) due to security changes
