RAL Tier1 Operations Report for 4th March 2019
Review of Issues during the week 25th February 2019 to the 4th March 2019. |
- ARC CE’s are all upgraded and running. Issue appears to be solved.
- gdss783 (ALICE disk) crashed and removed from production over the weekend (25th Feb). Back in production on Thursday 28th Feb.
- gdss776 (LHCb disk) is having ongoing problems. It crashed the previous week and was put back in, it has crashed last week and was put into read-only mode on 1st March. There is a copy of all LHCb data on Echo.
- Tuesday 26th February there was an intervention to physically move LHCb disk servers so that we could make room for the new deliveries.
- CPU efficiencies still problematic. Ongoing investigations/work.
