Alessandra requests: VOs using gridpp voms servers... please make sure you list all the GridPP VOMS servers HTCondor workshop in Europe: RAL (Oxfordshire, UK) 4-7 September 2018 WLCG SOC WG Workshop Registration for the HEPiX Fall 2018 Workshop is now open! Monday 25th June July pre-GDB: Authorization & Authentication Infrastructure for WLCG. Agenda. Documents. 100GbE networking workshop, London, 4th July Steve: who knows how to use xrdcp? 18th June WLCG ops meeting. Agenda and notes. 25th 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.

Tier-1 - Status Page Tue 25 June Report for the Experiments Liaison Report (02/07/2018) is here. ADVANCE WARNING : There is currently a scheduled three day period (July 24th - July 26th), where RAL Tier-1 will be undertaking server room circuit breaker testing. Although it is believed that these tests should not effect our services, such is the nature of these tests all Tier-1 production services should be considered "At Risk" during this time. All VOs are asked to give consideration with respect to possible unexpected outage to any high priority/critical jobs they may wish to run during this period.

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.

Tickets Monday 9th July 2018, 15.00 BST 29 Open UK Tickets this week - 14 IPv6 Tickets SUSSEX: 131617 Some positive news at the start of June, with the ETA on the network work required being the end of August. Is this still on course? In progress (4/6) RALPP: 131616 Back in January Chris was thumping IPv6 on his perfsonar boxes into shape. I don't think you're still flogging that problem. How goes things? In progress (31/1) OXFORD: 131615 Some good news delivered with some new switches back in March. Any update since then, now that Summer is well and truely upon us? On Hold (6/3) CAMBRIDGE: 131614 Last month John reported that the University was moving to a new address block and thus all v6 addressed would need to the changed. Prudently he's decided to hold back till then. Any idea on the timeline for the change? On hold (5/6) BRISTOL: 131613 At the last update Bristol admins were debating how to get an perfsonar box onto an IPv6 network back in April. Any luck with that? On hold (11/4) BIRMINGHAM: 131612 Some good progress IPv6-ing his perfsonar box back in May, did you get the v6 DNS working? On hold (28/5) GLASGOW: 131611 I don't want to really ask this, as I have an inkling as to the answer and it kind of feels like adding insult to injury, but how goes the new data centre? On hold (26/2) ECDF: 131610 The busiest v6 ticket by far, if I'm reading things right things are waiting until a big networking procurement in September. Is this still the case? On Hold (21/5) DURHAM: 131609 Any joy with this? Did the IT department get round to deploying v6 reverse DNS? In progress (4/5) SHEFFIELD: 131608 Things took at positive turn at the end of April, with news that the University would work towards deploying IPv6 - but it was only at the approving the work to be done level at that time. Any news since? On Hold (30/4) MANCHESTER: 131607 Good progress getting the perfsonar boxes dual-stacked, any plan of attack for doing the same for your DPM? On Hold (25/4) LIVERPOOL: 131606 Waiting on new routers to deal with the rubbish IPv6 performance Liverpool are seeing. Any news since last months update? In progress (4/6) UCL: 131604 Not much news here, Ben's been occasionally repoking UCL Networks. As noted UCL only need to dual stack their perfsonar boxes to satisfy this ticket. On hold (5/6) RHUL: 131603 At last update in February the perfsonars were dual-stacked but once again v6 DNS lookup wasn't supported yet - did they manage to get it working? On Hold (23/5) 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.
