General updates July pre-GDB: Authorization & Authentication Infrastructure for WLCG. Agenda. Documents. [https://www.jisc.ac.uk/events/100-gigabit-ethernet-networking-workshop-04-jul-2018 100GbE networking workshop, London, 4th July ] Steve: who knows how to use xrdcp? 18th June WLCG ops meeting. Agenda and notes. Monday 11th June There is a pre-GDB Tuesday on benchmarking. There is a June GDB on Wednesday. HEPSYSMAN is next week 18th-19th June - so no ops meeting next Tuesday. Winnie – 8th June problem with argo-mon.egi.eu Progress towards running LSST DESC data challenge on GridPP. Lack of multicore option in DIRAC for per VO basis. DPM 1.10.2 update issue dCache and IPv6: GridFTP doors and pools require that if a client can connect to an IPv6 address on an interface, that interface should also have an IPv4 address to which that client can connect. Brian: requested input last week to Hardware for Grid SE page. Of note: VO vo.geoss.eu status from Pending to Production APEL: delay in processing VM accounting records and new cloud data appearing in the Portal during the week of the 11th to 15th June. This is so that the APEL Repository can be updated to correctly assign the usage VMs incur to individual months when they run over month boundaries (i.e. long running VMs). This requires reloading a large volume of existing cloud accounting data once the update has been applied. May A/R (waiting for replies to 6th June request): ALICE All OK Atlas RHUL 81% Lanc 86% LHCB RHUL 76% Bristol 74% (Availability only) CMS Bristol 77% WLCG weekly ops meeting minutes from Monday 11th.

Tier-1 - Status Page Tuesday 11th June Report for the Experiments Liaison Report (11/06/2018) is here. Continuing problems with small VOs and Castor (BDii) - Please be advised that in the light of the impact on a number of smaller VO's the removal of this service has caused, that Castor information (at least in the short term), is now being published in the BDii. Storage & Data Management - Agendas/Minutes Wed 13 June Future directions for T2s with DPM? Assessing storage requirements for IRIS Wed 06 June Report from DPM workshop Wed 30 May Problems with deep vs shallow checksums in implementations - does the system present the checksum the data has or the checksum it thinks the data should have? IPv6 use - how to ensure IPv6 only transfers Wed 16 May Operational issues some of which at least are due to timeouts hardwired in the system. Report on CERN data lakes - still lots of questions, though. Maybe if we could try it out? Wed 02 May DPM DOME discussion... will Glasgow (or someone else) volunteer to test before DPM workshop? Storage agenda for HEPiX Tier-2 Evolution - GridPP JIRA Tuesday 5th Jun RHUL updated to Vac 3.0 / Vac-in-a-Box 1.0 last week, including support for custom network configurations (network interface bonding) Tuesday 15th May New WLCG Lightweight Sites WG starting: https://twiki.cern.ch/twiki/bin/view/LCG/LightweightSites Tuesday 8th May Updated the instructions in the wiki about supporting GridPP DIRAC Service VOs at Vac sites.

Monday 13th February This category is pretty much inactive. Are there any topics under "monitoring" that anyone wants reported at this ops meeting? 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 Tuesday 12th June Four availability tickets still open. One ticket on hold at RAL as they are figuring out that how to deal with castor publishing issue. Dashboard struggled during the week and it was slow but now it seems to be OK. One Bristol ticket got stuck in weird state where it can not be deleted from dashboard although it has been solved. Monday 21st May There was a problem with jobs accessing http://repository.egi.eu:80/sw/production/cas/1/current/meta/ca-policy-egi-core.list to get the latest release so many arc ce test fails. No tickets opened for these alarms and the problem went away when the underlying issue was fixed. Monday 5th March AM->GS. A quiet week last week. Rollout Status WLCG Baseline Monday 20th November IPv6: https://www.gridpp.ac.uk/wiki/IPv6_site_status (up-to-date as of November) Batch systems and WN moves to SL7/CentOS7: https://www.gridpp.ac.uk/wiki/Batch_system_status (added column for date of last update) Historical 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 25th June EGI IGTF CA update, version 1.92-1 ticket created [[https://rt.egi.eu/rt/Ticket/Display.html?id=14423 EGI #14423]] Tuesday 5th June Advisory update David now in post Meeting scheduled for this afternoon Tuesday 15th May Meeting scheduled for this afternoon Tuesday 8th May EGI IGTF CA update, version 1.91-1 ticket created [EGI #14315] Monday 30th April (David) Any feedback from the EOSC security communications meeting?

Services - PerfSonar production dashboard |PerfSonar development dashboard | OSG Networking and perfSONAR pages | 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). Monday 30th April The next LHCOPN and LHCONE joint meeting will take place on Tuesday the 30th and Wednesday the 31st of October 2018 Monday 19th February Please could sites upgrade their perfsonar hosts to CentOS7. Instructions are here. Current OS versions here. Duncan has recreated the UK perfSONAR mesh. Link here! Tickets Monday 25th June 2018, 15.00 BST 38 Open UK Tickets this week. BRUNEL 133956 (9/3) Any update for this CMS xroot ticket? The VO re-poked the ticket a few weeks ago and they were still seeing unwanted behaviour. In progress (15/6) TIER 1 135455 (31/5) CMS Checksums failing. After Chris cleared up some bad files it still looks like a few more persist at the last update. In progress (4/6) 135293 (23/5) ROD ticket for Castor after the publisher was took offline. Daniela notes that the alarms have gone from the dashboard and asks if things are fixed - I believe that a new (if temporary) publisher was put in place? On hold (25/6) SHEFFIELD 134947 (4/5) Atlas file transfers. It looks like atlas are just reusing the old ticket for the latest batch of failures they are seeing. Reopened (11/6) BRISTOL 134820 (29/4) Can we please close this CMS ticket? The VO doesn't seem bothered with it. In progress (1/5) RALPP 135552 (7/6) CMS SAM test failures after a disk node hit some troubles. Taking a look at the test pages it's looking nice and green again so I suspect this ticket can be closed too. ECDF 135404 (30/5) Low availability ticket. Looking at the monitoring I see some more blue negative availability days in argo, so it looks like some weird stuff has been going on. It'll be a while before the alarm clears itself (especially as the weekend wasn't great), so this ticket could do with being put on hold. In progress (4/6) Tools - MyEGI Nagios Monday 20th November The WLCG dashboard is available here: http://dashboard.cern.ch/. Please review the results on Steve's test pages. 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. VOs - GridPP VOMS VO IDs Approved VO table Monday 20th November Tom Whyntie has requested (and been granted) access to the GridPP VO to get some pipelines working for large-scale processing and analysis of MRI scans associated with the UK Biobank project. All VOs in the incubation page being prompted for updates by the end of November (required input for OC documents). QMUL (Steve L) is following up on the biomed MoU. GridPP want to be cited in research papers for the support our resources/sites provide. Impact Citation policy (https://www.gridpp.ac.uk/acknowledging.html) Site Updates Date
