Tier-1 - Status Page
|
Tue 20th November Report for the Experiments Liaison Report (20/11/2018) is here.
- On Thursday 15th November, all non-LHC VOs were migrated to the new consolidated Castor tape instance.
- CMS AAA issues are ongoing, although we may have finally turned a corner! It was found that certain CMS requests do not specify the Ceph pool to use (in this case it should be “cms”). There was no default pool set, thus the request fails. It was found that a bug meant that any subsequent requests would be sent to the (non-set) default pool causing all transfers to fail. This required a restart of the XRootD process. For the CMS AAA service we have added a default pool and monitoring of the logs, which will restart the process should it detect that transfers are using a non-set pool. SAM test results were at 96% over the weekend.
- We have been experiencing issues with Ceph/Echo ClusterVision 17 disk servers that were occasionally/randomly rebooting. This has now been resolved with a firmware patch that was rolled out last week. The hardware continues to be weighted up and we exceed 1Tb/s aggregated throughput on Friday 16th - graph below.

Storage & Data Management - Agendas/Minutes
|
Wed 21 Nov
- DPM sites: We are now not recommending not upgrading to DOME! unless you're using YAIM
- More operational issues on IPv6 routed networks
Wed 14 Nov
- Interesting operational issue switching ATLAS from SRM to xroot
- Do we have a "data management solution" and if so, what does it look like?
Wed 07 Nov
- More "data lake" and documentation
- Progress with caching but need to watch access patterns
Wed 31 Oct
- The role of EOS in the present and future GridPP
Wed 24 Oct
- GridPP storage and data management - well placed to contribute to IRIS
- Rucio+cache, proposed EOS evaluations, DOME testing update(s)
|
Tier-2 Evolution - GridPP JIRA
|
Monday 26th November
- VacMon running on a larger memory VM, again with CentOS7/ES5. Normal performance again.
- 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.
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.
