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.
