General updates 31st July new VAPOR release (2.3) ready for testing. Report issues via GGUS 129391. EGI OMB held on 27th July. Steve Lloyd's tests have been redeveloped as per our feedback. Please review and feedback. Tuesday 17th July There was a pre-GDB on singularity https://indico.cern.ch/event/578972/ There was a GDB on various topic. Notes from Monday's WLCG operations call are available here. EGI held an ops meeting yesterday. TB-SUPPORT topics Memory per core at https://www.gridpp.ac.uk/wiki/HEPSPEC06 Networking forward look - a reminder that Pete C is awaiting feedback from all sites. Check on enabling LSST (not all sites were used in recent campaign). WLCG Operations Coordination - AgendasWiki Page Tuesday 18th July The next WLCG ops coordination meeting is planned for September 14th 2017. Tuesday 11th July Agenda from Thursday's WLCG ops coordination meeting. Tuesday 4th July There will be a WLCG ops coordination meeting this week on Thursday at 14:30 BST. Agenda. The theme is 'providing reliable storage'. Minutes will be available. Tier-1 - Status Page Tuesday 22nd August A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here The CVMFS Stratum-1 service (a 2-node High-Availability cluster) is now dual stack with IPv6. All the 2015 capacity storage is now in Echo. As a result Echo now has around 13.4Petabytes of space raw. This gives approximately 10PBytes of usable space. Work is ongoing for Echo (CEPH) to re-balance its existing data across all the storage. This will take around three weeks in total. After that is completed the additional capacity can be used by the VOs. Storage & Data Management - Agendas/Minutes Wednesday 19 July Discussion of potential topics for data pre-GDB in September, without being able to commit yet Switching to fortnighly calls over the rest of July + August Wednesday 12 July Lots of loose ends including Matt's IPv6 testing Wednesday 05 July Continuing the WLCG workshop follow up, specifically looking at accounting and inforamtion publishing. On a related note, started looking at Swordfish again, more closely. Also provides REST-JSON API. Maybe we can do something Interesting(tm). Wednesday 28 June Lots of good blog posts! Lots of good presentations and discussions at both hepsysman and the WLCG workshop. Even if we didn't finish all the things... Tier-2 Evolution - GridPP JIRA Monday 24 Jul RHUL Vac site in production for LHCb and GridPP with Vac-in-a-Box. Some problems with Vac-in-a-Box installation being worked on (race condition in setting up the firewall) GridPP DIRAC and ATLAS jobs running at Cambridge Vac site. Problem with multiprocessor accounting and APEL identified but seems to only affect Glasgow significantly. Fixed in Vac 02.00.01 release. Tuesday 11 Jul Cambridge Vac site now in production for LHCb. ATLAS and GridPP being set up. Tuesday 4 Jul Cambridge Vac site set up and being tested for LHCb. GridPP DIRAC VMs using Pilot 3.0 now running at UCL, Imperial, Liverpool, Manchester, Glasgow, Oxford. Accounting - UK Grid Metrics HEPSPEC06 Atlas Dashboard HS06 Monday 16th January The discussion topic for next week will be accounting comparisons. Please note Alessandra's comments last week. Monday 14th November Alessandra has written an FAQ to extract numbers from ATLAS and APEL avoiding the SSB. Monday 26th September A problem with the APEL Pub and Sync tests developed last Tuesday and was resolved on Wednesday. This had a temporary impact on the accounting portal. APEL status: An issue at Sheffield? Documentation - KeyDocs Tuesday 25th July London grid (vo.londongrid.ac.uk) VO removed from Approved VOs. https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs Tuesday 4th July A round of reminders is coming! Need to ensure decisions captured regarding supported other VOs. General note See the worst KeyDocs list for documents needing review now and the names of the responsible people.

If not we will remove this section from the regular updates area of the bulletin and just leave the main links. Tuesday 1st December Sites are kindly invited to update the monitoring status page at https://www.gridpp.ac.uk/wiki/Site_monitoring_status Tuesday 16th June F Melaccio & D Crooks decided to add a FAQs section devoted to common monitoring issues under the monitoring page. Feedback welcome. On-duty - Dashboard ROD rota 6th June There are issues with the ARC CE tests again, so the ARC sites have not have any results in days and the corresponding availability tickets are going nowhere. New rota being compiled. Tuesday 2nd May Generally quiet. A few low availability tickets. Rollout Status WLCG Baseline Monday 13th February Please can we hear something from Raul and Sam (or others contributing to the middleware readiness work) about news in this area at the ops meeting next week?

Tuesday 15th September UMD 3.13.3 is available. Tuesday 12th May MW Readiness WG meeting Wed May 6th at 4pm. Attended by Raul, Matt, Sam and Jeremy. References Staged Rollout pages (now separated into EMI1 & 2), and the page listing the deployed versions is extractable from the bdii, so they should all be reasonably up-to-date: http://www.hep.ph.ic.ac.uk/~dbauer/grid/staged_rollout.html http://www.hep.ph.ic.ac.uk/~dbauer/grid/staged_rollout_emi2.html http://www.hep.ph.ic.ac.uk/~dbauer/grid/state_of_the_nation.html Security - Incident Procedure Policies Rota Monday 31st July Ian has now left GridPP.

Services - PerfSonar production dashboard |PerfSonar development dashboard | GridPP VOMS - This includes notifying of (inter)national services that will have an outage in the coming weeks or will be impacted by work elsewhere. (Cross-check the Tier-1 update). Tuesday 4th July Pete C is preparing another networking forward look document. Note that figures presented in the Manchester workshop were for a Tier-2 (not always a single site). Tuesday 6th June An update from the DIRAC workshop? GridPP is still the only true multi-VO instance, so we will continue to see issues with this. release quality of dirac has improved within the past year. gfal2/EL7 problems seem to be coming to an end after being cooped up with all authors for 3 days on end. The Imperial GridPP module now has integrated testing. It was also noted that every dirac instance has it's own special module to adapt to their community on top of main dira. We are trying to push as much of out special functionality back into the main dirac branch. Tuesday 25th April perfSONAR version 4 was released on 17th April. Sites with auto-update on should have been automatically upgraded. Note perfSONAR 4.0 requires more CPU than previous versions as a result of some of the increased functionality. Full details here Duncan has recreated the UK perfSONAR mesh. Link here! Tickets Tools - MyEGI Nagios Tuesday 18th July Following our ops discussion last week, Steve will focus his tests on supporting the GridPP DIRAC area and decommission the other tests. 29th November 2016 LSST monitoring is available through vo-nagios https://vo-nagios.physics.ox.ac.uk/nagios/cgi-bin/status.cgi?servicegroup=lsst&style=detail 13th September 2016 New wiki page has been created for ARGO Nagios https://www.gridpp.ac.uk/wiki/ARGO_Nagios_Monitoring. I will add some more information to it later. Removed old wiki links about sam nagios from gridpp wiki page. VO nagios still exist and working. I have opened a ticket to explore ARGO VO Nagios, https://ggus.eu/index.php?mode=ticket_info&ticket_id=123604 VOs - GridPP VOMS VO IDs Approved VO table Impact Citation policy (https://www.gridpp.ac.uk/acknowledging.html) Site Updates Date
