• CVMFS space for GridPP VO: /cvmfs/gridpp.gridpp.ac.uk or /cvmfs/gridpp.egi.eu
• supernemo data in Liverpool DPM - can it be removed?

Tuesday 16th June

• The minutes of the [GDB] last week are available.
• ATLAS has re-classified the following sites as “ATLAS Tier 3” in AGIS (this classification being based upon minimum resource requirements): UKI-LT2-UCL-HEP UKI-LT2-IC-HEP; UKILT2-Brunel; UKI-SOUTHGRID-SUSX and UKI-SCOTGRID-DURHAM.
• JANET is working with Imperial College to establish a VRF to perform tests of a connection to LHCONE.
• Please could everyone who supports gridpp ensure that the site accepts jobs with the pilot role? In addition please also consider the other VOs mentioned in Daniela's email (17:30 on 15th June).
• Glasgow: VO Shares and ARC CE config question.
• WLCG workshop 2016: last call for volunteers.

Tuesday 23rd June

• There was a WLCG ops coordination meeting last Thursday 18th June: Agenda. [1].
• Highlights: Information System discussion started. Use cases and dependencies will be built up and reviewed. May have a pre-GDB on topic.
• All sites should enable multicore accounting
• News: No update.
• Baselines: Removed WMS & L&B. LFC will be removed soon.
• MW issues: New globus-gss api released to mitigate problem reported last time.
• T0&1 services: T0 LHCb and shared LFC will be decommissioned 22nd June. Some dCache upgrades reported.
• T0 news: Efficiency meeting held. Cloud team making I/O changes. LHC exits see some improvement but T0 still behind other sites.
• T1 feeedback: NTR
• T2 feedback: UK response on Information System: Useful for service discovery; minor VO usage; contains too much information; cloud raises new questions; mixed data types; YAIM helpful to fill schemas.
• OSG: Provide InfoSys as service to VOs. Best case deprecation early 2016 but depends on USATLAS.
• InfoSys: HTC > GLUE in OSG. AGIS uses it (ATLAS seek merge of GOCDB, OIM and BDII). LHCb uses for CE discovery. CMS no clear usage. ALICE for SAM and CERN IT C5 reports.
• ALICE: High activity. CASTOR issue with xrd3cp. Request sites to plan for Xrootd v4.1.
• ATLAS: Good data taking. T0 some issues with batch/OpenStack improving. CERN network issue had impacts. CERN to BNL data backlog due to FTS not pushing hard enough.
• CMS: Data taking but technical stops. MC going well. T1 CPU should be 90% production role and 10% pilot. File transfer FNAL-RAL - possible WAITIO on storage nodes due to many CMS jobs.
• LHCb: Run2 offline processing workflows validated. Some issues with old files at RAL without checksums.
• gLEexec: NTR
• RFC proxies: SAM - okay now for ALICE. CMS PhEDEx instances being switched.
• Machine/Job features: NTR
• Middleware readiness: Good work. Credit to ECDF and GRIF for DPM work. New pakiti-client imminent in EPEL stable. MW readiness App now available on a production instance. EL7 support for ARGS urgent. Next meeting 16th September.
• Multicore: Several sites still not publishing. APEL tickets on NGIs. Issues identified for CREAM and ARC MC publishing.

  • 3. Experiment plans and operational issues (CMS; ATLAS; LHCb; ALICE and Others)
  • 4. Special presentations
  • 5. Actions
  • 6. Highlights for Operations Bulletin Latest
  • 7. AoB

Tuesday 23rd June

• The short outage last Wednesday (17th June) took place as planned. As agreed at last week's meeting we stopped/started the ToP BDIIs around this intervention. Following that we test need to plan a longer (few hour) outage for an intervention on our problematic router.
• DiRAC transfers from Durham now working.

Tuesday 23rd June

• Good progress with DiRAC transfers from Durham - data flowing since Monday.

Wednesday 17 June

• EU projects - SAGE: HSM for HPC
• Progress on new VOs. Can test as members of 'gridpp' or similar until they get their own allocations.
  • We've talked about it before; should VOs have individual T2 allocations to avoid stepping on each other's toes?
  • Case for expanding back-up-into-T1 to other VOs?

Wednesday 27 May

• Working on troubleshooting DIRAC data for/with LIGO (not to be confused with DiRAC or with any of the other things called DiRAC)
• Working on setting up DiRAC at Tier 1 (not to be confused with DIRAC or Dirac or with any other thing called Dirac)
• New secret user support list!

Tuesday 18th May

• Minutes are available.

Tuesday 21st April

• Has there been any Tier-1 contact with DiRAC?
• Proposal to setup an 'other VOs' users list. GridPP-Users is too tied with WLCG projects.

Wednesday 15 April

• Backing up data from DiRAC to GridPP (tape)
• More case studies on supporting non-LHC VOs on GridPP: we have a lot of great stuff that can do great stuff - non-LHC VOs tend to have less regimented data models so maybe we need more case studies.

Tuesday 16th June

• Region not publishing accounting by number of cores.
  • "0" core submission hosts:
  • ce3.dur.scotgrid.ac.uk
  • ce4.dur.scotgrid.ac.uk
  • cetest02.grid.hep.ph.ic.ac.uk
  • hepgrid5.ph.liv.ac.uk

Tuesday 9th June

• Delay noted for Sheffield

Tuesday 26th May

• Delay noted for Sheffield.

Tuesday 12th May

• Issues noted with sync for Brunel, Liv, ECDF (see EGI ticket 113473). Message broker issues (memory related) are likely the underlying EGI problem.
• Need to check on VAC sync publishing.

• A reminder to keep updating the HEPSPEC06 tables.

• APEL status: An issue at Sheffield?

Tuesday 23rd June

• Reminder that documents need reviewing!

Tuesday 9th June

LSST voms2 records are not present in VOID cards yet. As a workaround, a temporary note of the actual values has been added to the LSST section of Approved VOs.

https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs

General note

See the worst KeyDocs list for documents needing review now and the names of the responsible people.

Tuesday 21st April

• The Approved VOs document has been updated to take account of changes to the Ops Portal VOID cards.For SNOPLUS.SNOLAB.CA, the port numbers for voms02.gridpp.ac.uk and voms03.gridpp.ac.uk have both been updated from 15003 to 15503. Sites that support SNOPLUS.SNOLAB.CA should ensure that their configuration conforms to these settings: Approved VOs

• KeyDocs still need updating since agreements reached at last core ops meeting.

• Question of where to direct new VOs. EGI welcome page?

• New section in Wiki called "Project Management Pages".

The idea is to cluster all Self-Edited Site Tracking Tables
in here. Sites should keep entries in Current Activities
up to date. Once a Self-Edited Site Tracking Tables has
served its purpose, PM to move it to  Historical Archive 
or otherwise dispose of the table.

Monday 15th June

• There was an EGI operations meeting today: agenda.
• New Action: for the NGIs: please start tracking which sites are still using SL5 services: how many services, and for each service if still needed on SL5, if upgrades on SL5 services are expected). A wiki has been provided to record updates. Also interesting to understand who is using Debian.

Tuesday 21st April

• There was an EGI ops meeting on Monday 20th.
• David updated the UK SL5 response.
• Please review the agenda/minutes.

Tuesday 16th June

• FN & DC decided to add a FAQs section devoted to common monitoring issues under the monitoring page.
• Feedback welcome.

Tuesday 31st March

• Glasgow Graphite/Grafana documentation: http://www.scotgrid.ac.uk/graphite/

Monday 7th December

• Meeting last Friday - agenda: https://indico.cern.ch/event/356853/ minutes: https://indico.cern.ch/event/356853/material/minutes/1.pdf
• This was the wrap-up meeting of the consolidation TF; the mailing list will remain extant for a while yet.

Monday 22nd June

• Generally quiet. There are some 'glue2' errors that were ticketed. Tried to let these go and see if they would clear. However, in some cases the amount of time the error was outstanding was building up. Unclear if Glue2 is used anywhere.

Monday 8th June

• The eu.repository has now made a comeback, so the arc alarms, cleared, but I the site availabilities (probably) need to be corrected.
• Still getting on/off bdii alarms for a variety of sites.

Monday 11th May

• Rota responses awaited from Andrew and Daniela.
• Handover summary should be uploaded to the bulletin please.

Tuesday 12th May

• MW Readiness WG meeting Wed May 6th at 4pm. Attended by Raul, Matt, Sam and Jeremy.

Tuesday 17th March

• Daniela has updated the [ https://www.gridpp.ac.uk/wiki/Staged_rollout_emi3 EMI-3 testing table]. Please check it is correct for your site. We want a clear view of where we are contributing.
• There is a middleware readiness meeting this Wednesday. Would be good if a few site representatives joined.
• Machine job features solution testing. Fed back that we will only commence tests if more documentation made available. This stops the HTC solution until after CHEP. Is there interest in testing other batch systems? Raul mentioned SLURM. There is also SGE and Torque.

Tuesday 23rd June

• GridPP issued a position statement regarding LHCONE.
  • ...Concerning LHCONE for both T1 and T2. The high level summary is that the UK is not in favour, as within the UK we have no explicit need for LHCONE for any reason of T1 capacity planning, but to implement it involves additional complexity and possibly cost. The current system works fine and we therefore see no overriding reason to remove T1-T1 transit via LHCOPN. ...The UK is sensitive to the “collective” needs of the community, and as a general statement we would always seek to address any legitimate request agreed by the WLCG MB in order to play our role in meeting international expectations.

35 Open UK Tickets this week (!!!)

GridPP Pilot Role
A dozen of them are from Daniela (who painstakingly submitted them all) concerning getting the gridpp (and other) pilot role enabled on the site in question's CEs.

An example of one of these tickets is:
114440 (Lancaster's smug solved ticket).

Ticketed sites are: Durham, Bristol, Cambridge, Glasgow, ECDF (who are also having general gridpp VO support problems), EFDA-JET (looking solved), Oxford, Liverpool, Sheffield, Brunel, RALPP and RHUL. Most tickets are being worked on fine, but the Bristol and Liverpool ones were still just in an "assigned" state at time of writing.

Core Count Publishing
114233 (10/6)
Of the sites mentioned in this ticket (Durham[1], IC, Liverpool, Glasgow, Oxford) who *hasn't* had a go at changing their core count publishing? I know Oxford have. Daniela had a pertinent question about publishing for VMs, which John answered. In progress (17/6)

[1] Durham have another ticket on this which may explain their lack of core count publishing: 114381 (16/6)

DIRAC
114379 (16/6)
Sam S formed this ticket over having trouble accessing the majority of SEs over Dirac, after some discussion around this last week. Sam acknowledges that this could be a site problem, not a DIRAC problem, but you gotta start somewhere (he worded that point more eloquently). Daniela has posted her latest and greatest DIRAC setup gubbins for Sam to try out. Another, unrelated, point to have are the names missing from Sam's list - for example I'm pretty sure Lancaster should support gridpp VO storage but I've forgotten to roll it out! Waiting for reply (22/6)

LIVERPOOL
114248 (10/6)
Final ticket today, and another one discussed last week in the storage meeting. Steve's explanation of why (and how) Sno+ would need to start to using space tokens was fantastically well worded in a way to not spook easily startled users. David is digesting the information, but it will likely need to wait for Matt M's return before we'll see progress. In progress (16/6)

MANCHESTER
114444(18/6)
I told a pork pie when I said that was the last ticket - this one caught my eye. A ticket from lhcb over files not having their checksums stored on Manchester's DPM. A link was given to another ticket at CBPF for a similar issue which got the DPM devs involved (111403) - although Andrew McNab was already subscribed to the ticket. In progress (19/6)

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.
