RAL Tier1 Operations Report for 20th August 2018
| Review of Issues during the week 13th August to the 20th August 2018. |
- The upgrade of Echo was completed successfully on Thursday (16/8/18), with a greatly reduced memory usage. The cluster was allowed to recover overnight. Everything appeared to be working well on the Friday (17/8/18), and there is currently no evidence of data loss. We therefore ended the downtime at Friday 12:00 UTC (17/8/18). As a precaution for the weekend, we limited the ATLAS (and CMS), quota on our batch farm to 50% of its nominal amount. Assuming we encounter no problems we intend to lift this on Monday (20/8/18).
