13:55 → 14:05 VO Liaison LHCb

Speaker: Alexander Rogovskiy (Rutherford Appleton Laboratory)

Operational issues:

• There were a lot of slow requests on ECHO, causing some problems for LHCb. Tracked in CS-250
• Minor issue with antares uploads two weeks ago, might be due to network problem between CERN and RAL (?)
  
  

 

News:

• Xrootd 5.7.1 deployed to the farm, that concludes the long story of the vector read issue (at least for now).
