RAL Tier1 Operations Report for 14th January 2019

Review of Issues during the week 7th January 2019 to the 14th January 2019.
  • With the minor exceptions below, it's still (suspiciously!), calm and peaceful at the Tier-1. Very much business as usual.
  • Ongoing issues with ARC CEs. Not causing significant operational issues yet. We have identified a large number of LHCb MCFastSimulation jobs that are probably creating the load on the system.
  • On Wednesday 9th January an Echo storage node started rebooting itself and was removed from the cluster. No loss of availability to the cluster. Engineer to attend site to fix.
