| General updates
Tuesday 1st September
- From October/November, the EGI ops VO monitoring will be performed using RFC proxies, as opposed to legacy proxies.
- There will be a new filter for the critical profile for ATLAS WLCG SAM tests so that only production endpoints will be tested and taken into account for site availability metrics. This will be available from the SAM3 interface.
- CNAF: Due to a fire causing problems with one electrical supply line that happened last Thursday, the computing centre is running at lower capacity (around 30% less of the pledged capacity).
- Machine job features testing has hit a big according to Raul!
- The HNSciCloud PCP pilot proposal successful submission (refer to Andrew Sansum's talk at GridPP34 if you forget what this means!). The project intends to procure commercial cloud resources for FY17 and FY18. We will contribute 75K euro towards this activity and the EU will then top up to 250K euro.
- There was an EGI Operations Management Board last Thursday. There are no summary notes yet, but please take a look at the agenda and linked talks (may be worth skimming them at the ops meeting).
- There was a quick request/reminder for sites to please update their IPv6 entries in the GridPP wiki.
- RAL is closed on Monday and Tuesday of this week!
Tuesday 24th August
Tuesday 18th August
- Root CA - Jens will provide a quick incident report of what went wrong!
- Notes from Monday's WLCG ops meeting are available.
- DPM tuning (raised my Matt D - 17/08)
- Developers@CERN Forum is an initiative of a group of developers targeting all software developers at CERN.
- Multicore inefficiencies: RAL - CMS allocated slots not used. Glasgow - the concern for us is CPU that was previously being used by ATLAS is no longer being used because of multicore size mismatches.
- RIPE ATLAS probe experience pages.
- Automating ATLAS consistency checking (See Alastair's email 12/08)
- For generating docs out of markdown Steve T can recommend gitbook. This is what CERN use for the Config guide.
| WLCG Operations Coordination - Agendas
- There was a middleware readiness meeting on 16th September.
- The new DPM version is being tested via the ATLAS workflow by the Edinburgh Volunteer site.
- Many new sites showed interest to participate in MW Readiness testing with CentOS7. It is useful to anticipate the MW behaviour in the event of new HW purchase. DPM validation on CentOS/SL7 is already ongoing at Glasgow.
- ATLAS and CMS are asked to declare whether the xrootd 4 monitoring plugin is important for them or not. As it is now, it doesn't work with dCache v. 2.13.8
- Despite the fact that FTS3 runs at very few sites we decided to test it for Readiness. In this context, ATLAS and CMS are asked to use the FTS3 pilot in their transfer test workflows
- PIC successfully tested dCache v.2.13.8 for CMS.
- CNAF has obtained Indigo-DataCloud effort to strengthen the ARGUS development team. The ARGUS collaboration will meet again early October. The problems faced at CERN with a CMS VOBOX are being investigated in ticket GGUS:116092.
- The next MW Readiness WG vidyo meeting will take place on Wednesday 28 October at 4pm CET.
Tuesday 25th August
- Minutes from the meeting last Thursday are available.
- Calling for volunteers to write articles on interesting topics for WLCG Operations. There is a section in the portal for this. In case you are interested, please send a mail to wlcg-ops-coord-chair people for details.
- CERN is going to disable in few weeks write operations via RFIO v2 to Castor in the context of the RFIO access decommission.
- A downtime for the Argus service @ CERN is expected due to the pending filer migration. No dates yet but it will affect ARGUS, all CEs and all batch worker nodes (glExec) running GridJobs. The downtime is foreseen to last 1h-2h.
- Issues with VMs in Tier-0 infra also reported by CMS
- LHCb is trying to integrate submission to the HTCondorCE instance @ CERN
- A message broker pre-prod infra has been setup @ CERN to enable distribution of perfSONAR data to the experiments. OSG is enabling the data publication from the ITB collector service
- Please observe the Action List in the minutes and on the WLCG Operations portal by clicking on the Task List relevant to: Sites: Experiments.
Tuesday 18th August
| Tier-1 - Status Page
Tuesday 22nd September
A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here
- The production FTS was updated (to version 3.3.1) on Wed. morning (16th). The production FTS server has been under high load and has been showing performance problems.
- The first step of the update of the Oracle databases behind Castor was made on Tuesday 15th. There are further steps to do - as announced in the GOC DB.
- There will be an 'at risk' on the morning of Wednesday 30th Sep. as the Tier1's link into the RAL core network is upgraded to 40Gb.
| Storage & Data Management - Agendas/Minutes
Wednesday 02 Sep
- Catch up with MICE
- How to do transfers of lots of files with FTS3 without the proxy timing out (in particularly if you need it vomsified)
Wednesday 12 Aug
- sort of housekeeping: data cleanups, catalogue synchronisation - in particular namespace dumps for VOs
- GridPP storage/data at future events; GridPP35 and Hepix and Cloud data events
Wednesday 08 July
- Huge backlog of ATLAS data from Glasgow waiting to go to RAL, and oddly varying performance numbers - investigating
- How physics data is like your Windows 95 games
Wednesday 01 July
- Feedback on CMS's proposal for listing contents of storage
- Simple storage on expensive raided disks vs complicated storage on el cheapo or archive drives?
Wednesday 24 June
- Heard about the Indigo datacloud project, a H2020 project in which STFC is participating
- Data transfers, theory and practice
- Somewhat clunky tools to set up but perform well when they run
- Will continue to work on recommendations/overview document
- Worth having recommendations/experiences for different audiences - (potential) users, decision makers, techies
| Tier-2 Evolution - GridPP JIRA
Thursday 17 Sep
- Task force to start developing advice for sites to simplify their operation in line with "6.2.5 Evolution of Tier-2 sites" in the GridPP5 proposal.

Tuesday 28th July
- Ewan: /cvmfs/gridpp-vo help ... there's a lot of historical stuff on the GridPP wiki that makes it look a lot more complicated than it is now. We really should have a bit of a clear out at some point.
Tuesday 23rd June

| On-duty - Dashboard ROD rota
Tuesday 1st September
- Gordon was on shift.
- Another very quiet week with no new tickets. We have two open ROD tickets, both of which are for A/R; one is against Cambridge, and the other is the now 53-day-old ticket at UCL.
- Next up.... Kashif again (thanks Kashif!)
Monday 24th August
- Kashif on shift.
- There were quite a few alarms throughout the week and many tickets were opened. All of the tickets were fixed within time limit.

- Cambridge and UCL have low availibilty tickets and not much can be done about it except waiting for availibilty to reach 90%.
| Services - PerfSonar 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 18th August
Tuesday 14th July
- GridPP35 in September will have a part focus on networking and IPv6. This will include a review of where sites are with their deployment. Please try to firm up dates for your IPv6 availability between now and September. Please update the GridPP IPv6 status table.
| Tools - MyEGI Nagios
Tuesday 09 June 2015
- ARC CEs were failing nagios test becuase of non-availability of egi repository. Nagios test compare CA version from EGI repo. It started on 5th June and one of the IP addresses behind webserver was not responding. Problem went away in approximately 3 hours. The same problem started again on 6th June. Finally it was fixed on 8th June. No reason was given in any of the ticket opened regarding this outage.
Tuesday 17th February
- Another period where message brokers were temporarily unavailable seen yesterday. Any news on the last follow-up?
Tuesday 27th January
- Unscheduled outage of the EGI message broker (GRNET) caused a short-lived disruption to GridPP site monitoring (jobs failed) last Thursday 22nd January. Suspect BDII caching meant no immediate failover to stomp://mq.cro-ngi.hr:6163/ from stomp://mq.afroditi.hellasgrid.gr:6163/
