Tue 11th December Report for the Experiments Liaison Report (10/12/2018) is here.
- Argo tests for CMS Castor were failing on Monday and Tuesday last week (3rd and 4th December). This was as a result of a BDII problem (it stopped publishing the information).
- There was a successful load test of the generator on Wednesday,
- ~5% of SAM tests via GridFTP against Echo have been failing due to the “Address already in use” problem. We are investigating the problem and disabled NIS on the gateways as it is not needed and was using up ~13000 ports. We are monitoring to see if the situation improves.
- CMS successfully migrated to the new consolidated Castor tape instance on Thursday (6th December).
- The physical machine hosting MySQL databases for the Tier-1 (RT ticket system + LFC) died on Thursday. The service was restored from backup on Friday on a VM.

- https://vacjson.gridpp.ac.uk/ has prototype CRR JSON files (ie the BDII replacement) generated on the fly from the VacMon ElasticSearch database. These are for all sites (UK + CERN + YANDEX) reporting Vac/Vcycle status to VacMon. There is a corresponding InformationSystem extension in GOCDB to declare the URL of the CRR JSON file.
- General note: there is a GitHub repo for scripts and sample JSON files which sites want to share.
Tuesday 22rd October
- VacMon monitoring pages running again, on CentOS7/ES5. Still slower than previous SL6/ES5 machine so may try again in a larger memory VM.
