General updates Monday 22nd May Issue with dirac-dms-get-file affecting vo.moedal.org. HTCondor workshop in Europe 2017 6th-9th June. More information. ARGO Monitoring Downtime - Tuesday, 23 May, at 7:00 AM CEST, there will be scheduled down time for approximately 6 hours. 2017 WLCG Workshop: registration extended Downtime declarations discussion (3days or 5 days notice....!) CHEP papers - final weeks for revisions. Fourth release of the Accounting Portal ready for testing. Feedback via GGUS 127920. Final T2 availability & reliability - April 2017. CA reminders... some observations Reminders are working as well as they always have Special case if you have multiple certs which expire soon after the other [which isn't actually permitted and hence not expected] the reminders come late Please don't send CA tickets to TB-SUPPORT as it is a publicly visible mailing list and if things turn into non-issues then can be seen as bad advertising for no reason Don't rely on the CA to remind you – setup your own reminders "fixing" this issue (multiple certs) is plausible, but as it is deep within code (there are several levels of code involved here in more than 1 language) then it might be error-prone and hard to test. EGI Operations Broadcast - May 2017 Failures with CREAM-CE JobCancel probe Decommissioning of dCache 2.10 Notes from the May GDB are now available. Tuesday 16th May There was a GDB last Wednesday. Agenda | Notes. If attending, please register ASAP for the WLCG workshop to be held June 19-22 in Manchester. Submit a GridPP travel request. An IPv6 working group meeting takes place today at CERN. GOCDB information review now completed. The PMB is currently preparing documentation for an upcoming oversight committee meeting. EGI conference and Indigo summit took place last week. Steve: Grid jobs sending email! LHCb week - agenda. Tuesday 9th May April R/A draft figures available ALICE All okay. ATLAS QMUL: 82%:83% Birmingham: 86%: 86% RALPP: 86%:86% CMS RALPP: 78%:78% LHCb QMUL: 65%:66% RALPP: 72%:72% HEPSYSMAN topics proposed & call for more. There is a GDB this Wednesday. Agenda. Notes from yesterday's WLCG ops meeting are available. WLCG workshop registration reminder. GridPP is going to pay for the travel expenses TB-SUPPORT discussions: Elena: Xeon E5-2640 v4 or E5-2650 v4. Questions about hardware. Andy: transfer source checksum operation timed out error. Reminder of the GOCDB information review. Please update the GridPP table created by Matt. Looks like just RAL Tier-1 and ECDF to be checked. Created storage sites status as per action O-170124-01 Created a "Site status" category to group pages where we track sites status. Please add it to the pages you know which are not already listed. WLCG Operations Coordination - AgendasWiki Page Monday 22nd May WLCG ops coordination took place last Thursday with a theme of "providing reliable storage" : Agenda | Minutes. Tuesday 16th May WLCG ops coordination meeting this Thursday 18th. The theme is "providing reliable storage". Tuesday 9th May Nothing scheduled in the agenda pages for WLCG ops. Tier-1 - Status Page Tuesday 30th May A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here The LHCb Castor instance was upgraded to version 2.1.16 on Thursday 11th May. The Atlas instance was upgraded on Tuesday 23rd and the CMS instance on Thursday (25th). The "GEN" instance is scheduled for Wednesday 31st May. Atlas now have 2PBytes of data in ECHO which is their current allocation in there. This means Atlas' use of ECHO will now need to include deleting data to make room for more. (Note: ECHO has more capacity than this in total.) Work is going on enable use of the Tier1 by LIGO (batch, Echo storage and cvmfs) and CCP4 (for batch). The new version of FTS3, installed on our "test" FTS service (used by Atlas) no longer supports the SOAP API. There are still some access to our "production" FTS3 service via this API (mainly SNO+ and MICE). We will wish to upgrade the production FTS3 service - and need VOs to move to the rest API provided with the newer versions of FTS. Would like to set deadline when we upgrade the "production" instance and hence no longer support the SOAP API. Storage & Data Management - Agendas/Minutes Wednesday 17 May Lots of opportunities to contribute to WLCG workshop (if we could finish all the stuff we've got cooking) Wednesday 19 Apr Case for (re)testing CVMFS for T2s? (and non-LHC VOs?) Other storage related issues arising from use of containers? Wednesday 12 Apr Musings on the outcome of last week's GridPP meeting Discussion of which of a selection of coming events to aim to do something for. If that makes sense, gramatically. Wednesday 15 Feb Space tokens! Use them! Leafed through interesting topics (technology permitting) from the CS3 workshop Tier-2 Evolution - GridPP JIRA Tuesday 16 May Updated GridPP DIRAC VMs. Passing with some tests jobs but still investigating some failures. Tuesday 2nd May There was a GridPP technical meeting last Friday. 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 Tue 23rd May As part of the process of moving everything to Centos7 (or some other form of RHEL7), I've written up how we build nodes at Liverpool for our ARC/Condor system. https://www.gridpp.ac.uk/wiki/Centos7_Adoption I hope it's also a decent cheatsheet for Puppet3/Hiera. It's a draft, and I need to put in some more details, but it should be usable. Tue 7th Mar I want to get rid of following stale docs... Ten Easy Network Questions GridPP Answers to 10 Easy Network Questions SL5 status Glasgow Middleware Operations Logbook London Tier2 Shares 23rd June 2010 Special Topic: NGS Technical Roadmap - Pete Gronbech SAM availability: Monthly summary table Transfer Tests Birmingham Endpoints EVO Tips and Tricks BaBar: bbrbsub270 Monday 13th Feb Please check the keydocs page. Would all owners please review their pages and prepare a short note on how they will bring things up-to-date in the coming months. This will be discussed at a core ops meeting (poll to be circulated shortly). There are several EGI operations document updates out for review. Please make comments to Jeremy by 20th Febraury for inclusion in the UK feedback: - Resource Centre OLA https://documents.egi.eu/document/31 - Resource Infrastructure Provider OLA https://documents.egi.eu/document/463 - Corporate-level EGI OLA https://documents.egi.eu/document/2752 Monday 30th January The fusion VO has been removed from GridPP Approved VOs. Monday 9th January Tom put these together: A snapshot of the GridPP UserGuide is now available as an offline document in the Zenodo repository: ...and the v1.0 release of the LaTeX code used to compile it is here. There are some minor differences (mainly hyperlink-related) to the online version [1], which has also had a v1.0 release here. Tue 22nd Nov More on Accounting audit tools The process for ARC, Toque and VAC is now documented here. https://github.com/gridpp/audit/wiki General note See the worst KeyDocs list for documents needing review now and the names of the responsible people.

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 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 Monday 6th March Last week it was noted that some ATLAS RIPE probes (the USB ones) have had hardware errors. If you need a replacement and RIPE are slow to respond then contact Jeremy. Is anyone running any tests with their RIPE probe? Tuesday 14th February The development dashboard is now operational again. However the production dashboard is not currently displaying latency results (OSG ticket submitted). Birmingham pS host had lost its entire network connection and both Lancaster's hosts their IPv6 connection. Durham results are incomplete, GGUS ticket submitted (#126587). Tuesday 25th October Duncan has recreated the UK perfSONAR mesh. Link here! Tickets Wednesday 24th May 2017 Due to the Bank Holiday and Matt being on leave for the Ops meeting here's a a link to all the UK tickets to tide you over. Hope everyone had a nice weekend!
