RAL Tier1 Operations Report for 17th January 2018
Review of Issues during the week 10th January 2018 to 17th January 2018 |
- Over the weekend (13/14 Jan) LHCb were running merging jobs and this caused problems for LHCb Castor. The on-call team responded - and the problems stopped when LHCb eased back on this workload.
- Also over the weekend there was a problem with the Atlas Castor SRMs which stopped working for some hours. The SRMs started working on their own. However, the problem has recurred and further investigations have been taking place.
- CMS AAA redirection problems were reported at the end of last week. Investigations continue but this appears to be affecting other sites too and may not be a local RAL Tier1 problem.
