Week commencing 6th July 2015
Task Areas
General updates

Tuesday 7th July

  • Reminder: on July 17 a 4 hour long EGI Federated Cloud tutorial will be organised in London (at SAP near Heathrow). It's a free event, part of a 3-day long software carpentry workshop.
  • Q2 15 quarterly reports are now due!
  • There is a UKNGI ticket on multicore accounting that still requires some sites to act.
  • Proposal for a DPM workshop 16-17th of November or possibly 19-20th. Any comments?
  • The draft T2 reliability and availability figures for June have been produced.
    • ALICE: All okay.
    • ATLAS: All okay.
    • CMS: Bristol (89%:100%) - so just under the cut-off.
    • LHCb: Sheffield: (64%:64%); RALPP: (83%:83%).
  • EGI Community Forum 2015: Call for Participation open! Deadline: 12 July
  • A summary of a recent ARGUS collaboration meeting is now available.
  • There is a WLCG GDB this week.


Tuesday 30th June

  • Steve's GridPP tests relied on the CERN LFC (ATLAS) which was removed last week. We need to review what tests if any we still want to run in the UK. Do we?
  • A new mailing list has been setup for the discussion of batch and CE matters in WLCG: project-lcg-gdb-batch at cern.ch.
  • Some have noted that the GOCDB was not sending out downtime notifications. A ticket was raised.
  • A preliminary draft of the July GDB agenda is available.
  • In In order to get the broadest input EGI has prepared a survey (deadline July 7th).
  • There was an EGI OMB last week. Please take a look at the brief minutes and actions.
  • The SAM tests used for ATLAS Availability and Reliability of SEs are going to be changed to new gfal2 DDM-probes from 1st July. The new monitoring is already running at: http://wlcg-sam-atlas-dev.cern.ch/ (the name of the tests are: DDM-srm-Del; DDM-srm-Get and DDM-srm-Put.From 1st July these will move to http://wlcg-sam-atlas.cern.ch/.
  • The camont collaboration is no longer active, but the VO is enabled and useful. Previous contributors to the camont work would like to re-purpose the VO to support the Cambridge 'Geant Human Oncology Simulation Tool’. Providing we broadcast any change to sites supporting camont and the AUP changes (and all users re-sign it), is there any objection to this pragmatic solution (it fits well our current aim of getting varied communities using our resources successfully).


WLCG Operations Coordination - Agendas

Tuesday 7th July

  • There was an ops coordination meeting last Thursday 2nd July. Agenda: Minutes.
  • Highlights: The next WLCG workshop will take place in Lisbon in the first week of February 2016 and organised by LIP. A new version of UMD (3.13) has been released. The size of the HTCondor pilot service at CERN is now 300 cores and fully used. Agreed to establish a full, WLCG-wide perfSONAR mesh for the top 100 sites .
  • Baselines: New version of UMD ( v 3.13): Fixes/improvements for: gLexec; CREAM; StorRM; dpm-xrootd; fetch-crl.
    • New version of the WN tarball (3.15.3-1_sl6v1) published to CVMFS grid.cern.ch, it includes updates and the gfal2-util package for the first time.
  • Issues: NTR
  • T0/T1 services: LFC decommissioned. Various T1 storage updates.
  • T0 news: Condor prototype at CERN: We have now increased the pool size to almost 300 cores; ATLAS T0 LSF instance: the required capacity (110 KSpec) has been provided; The T0 receives more and more tickets (coming from GGUS or directly from SNOW) which are related to experiment support.
  • T1: NTR
  • T2: NTR
  • ALICE: 80k concurrent jobs reached for many hours on Jun 21-22. Failed jobs due to CVMFS cache corruption; network incident Fri evening Jun 26 caused all VOBOXes for CERN to become unreachable; latest CASTOR versions are incompatible with old xrd3cp implementation.
  • * Tier-1 sites requested to upgrade to Xrootd 4.1 (or newer).
  • ATLAS: seeing lost files due to interaction between Rucio/FTS, something in Rucio, something in FTS.
  • CMS: Good utilization; Faulty MC production workflows seen (me allocations >100GB); Root certificate of Spanish CA recently expired at some sites.
  • LHCb: Problems with DPM SEs at T2 sites. Some files had no checksum. Checking and recovering checksum for all files.
  • WLCG site survey on GGUS: Pablo reports the high level of satisfaction (98%). Some requests already supported. Some common issues reported (like lack of detail in tickets). See slides.
  • gLExec: NTR
  • RPF proxies: proper patch of the proxy renewal sensor for SAM is available.
  • Machine/job features: NTR
  • MIddleware readiness: Latest version of pakiti-client (v3.0.1) with tag support has been pushed to EPEL stable; PIC and Brunel are collaborating for PhedeX tests. This allows PIC to better compare one site against another. Next meeting Wednesday September 16th at 4pm CEST.
  • Multicore deployment: John Gordon will send out a broadcast and produce an updated list of missing CEs. Action should stay until all sites done.
  • IPv6: NTR.
  • Squid monitoring & HTTP proxy discovery: Little reported.
  • Network & transfers: Agreed to establish WLCG-wide meshes for top 100 sites (based on the contributed storage and location). This will enable full mesh testing of latencies, traceroutes and throughput; perfSONAR 3.5 RC is planned to be released this week. Next meeting will be on 8th of July.
  • HTTP deployment: NTR.
  • See site actions.


Tuesday 30th June

  • A new WLCG ops portal will be live soon. If you are particularly keen to give feedback please contact Jeremy


Tier-1 - Status Page
  • A reminder that there is a weekly Tier-1 experiment liaison meeting.
  • The agenda follows this format:
    • 1. Summary of Operational Status and Issues
    • 2. Highlights/summary of the Tier1 Monday operations meeting (Grid Services; Fabric; CASTOR and Other)
    • 3. Experiment plans and operational issues (CMS; ATLAS; LHCb; ALICE and Others)

Tuesday 7th July

  • Little planned this week as there are open days at RAL.
  • Planning an intervention by the vendor on our faulty router - likely to be an outage of the Tier1 on 4th August (to be confirmed).
  • Currently our OPS availablity is hit by the problem of the ARC-CE test that fails.
Storage & Data Management - Agendas/Minutes

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

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!



Accounting - UK Grid Metrics HEPSPEC06 Atlas Dashboard HS06

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
    • hepgrid6.ph.liv.ac.uk
    • hepgrid97.ph.liv.ac.uk
    • svr009.gla.scotgrid.ac.uk
    • t2ce06.physics.ox.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.


Documentation - KeyDocs

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.
  • 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.
Interoperation - EGI ops agendas

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.


Monitoring - Links MyWLCG

Tuesday 16th June

  • F Melaccio & D Crooks decided to add a FAQs section devoted to common monitoring issues under the monitoring page.
  • Feedback welcome.


Tuesday 31st March

Monday 7th December

On-duty - Dashboard ROD rota

Monday 6th July

  • DB: Between the fake ARC alarms and the fake bdii alarms it's hard to see the real alarms.

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.


Rollout Status WLCG Baseline

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.

References


Security - Incident Procedure Policies Rota

Monday 29th June

  • EUGridPMA have announced a new set of CA rpms. Based on this IGTF release a new set of CA RPMs have been packaged for EGI. There is a request to please upgrade within the next seven days at your earliest convenience. When this timeout is over, SAM will throw critical errors on CA tests if old CAs are still detected.
  • The next security team meeting is this Wednesday 1st July.

Tuesday 16th June

  • Security team meeting this Wednesday.
  • One topic for review concerns ES.

Tuesday 9th June



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 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.

Tuesday 12th May

  • LHCOPN & LHCONE joint meeting at LBL June 1st & 2nd. Agenda taking shape.

Tuesday 31st March

Tickets

Monday 6th July 2015, 14.00 BST
30 Open UK Tickets this month. Looking at them all!

NGI
114233 (10/6)
The UK not publishing core counts at all sites. Some progress, but at last check John G couldn't see a change for Oxford or Glasgow. In progress (30/6)

RALPP
114442 (18/6)
Gridpp Pilot role ticket. Accounts need to be created, but no word for a few weeks. In progress (19/6)

114764 (1/7)
Ticket tracking (false) availability issues, created to appease COD - the problem caused by a broken CA rpm release for Arc CEs. Kashif has created a counter-ticket 114742 Gordon's sagely advice is to submit a recalculation request once the issue is fixed. Assigned (1/7)

BRISTOL
114485 (19/6)
Bristol's gridpp pilot role ticket. No news, could do with an update really. In progress (22/6)

114426 (18/6)
CMS AAA reading test problems. The Bristol admins have transferred data to their new shiny SE and have asked CMS to test again. No word since. Waiting for reply (30/6)

EDINBURGH
95303 (1/7/13...)
Tarball glexec ticket, now 2 years old. After a really promising burst the last 6 weeks haven't seen any progress, due to a lot of other "normal" tarball work taking up the time. Sorry! On hold (18/5)

DURHAM
114536 (22/6)
Durham's gridpp pilot role ticket. Not acknowledged yet, is Oliver back yet? Assigned (22/6)

114765 (1/7)
See RALPP ticket 114764. Assigned (1/7)

114727 (30/6)
Catalin ticketed that a number of SW_DIR variables at Durham are still pointing to the old school .gridpp.ac.uk cvmfs space. Assigned (30/6)

114381 (16/6)
John G ticketed Durham over a small percentage of jobs being published as "zero core". Looks like a SLURM timeout problem, although a fix isn't obvious. Put on the back burner whilst Oliver is on holiday. On Hold (19/6)

SHEFFIELD
114649 (26/6)
A ticket from a Sno+ user about not being able to access software using the Sheffield CEs. Acknowledged but no news. In progress (26/6) Update - Elena can't find anything wrong, cvmfs seems to be working fine. Perhaps a problem with the environment?

114460 (18/6)
Sheffield's gridpp pilot role ticket. Did you get round to rolling them out? In progress (19/6)

MANCHESTER
114444 (18/6)
LHCB ticket concerning the DPM's SRM not returning checksum information. On hold whilst a related ticket is being looked at (111403). On Hold (22/6)

LIVERPOOL
114248 (10/6)
Another Sno+ ticket, about grid production jobs failing at Liverpool. AIUI caused by Sno+ running out of space on the shared pool. At last check Steve posted the usage information for Sno+ but no word since (and Steve's off on his hols). In progress (17/6)

LANCASTER
114845 (6/7)
LHCB pilots failing at Lancaster. Looks like a simple node misconfiguration, hopefully fixed, waiting to see if it is. On hold (6/7)

95299 (1/7/2013)
glexec ticket - see Edinburgh description. On hold (15/5)

100566 (27/1)
Bad bandwidth performance at Lancaster. Hoping that IPv6 will shake things up a bit so pushing that. On hold (18/5)

UCL
114746 (30/6)
SRM-put failures ROD ticket. No news at all. Assigned (30/6)

114851 (6/7)
Low availability ROD ticket, related to above. Assigned (6/7)

RHUL
114441 (18/6)
Another GridPP pilot role ticket. Pilots rolled out, but something isn't quite right and they're not working - Govind is looking again. In progress (6/7)

QMUL
114573 (23/6)
LHCB ticket about two out of three QM CEs not responding for them. Dan spotted the broken CEs were dual-stacked, the working one wasn't. The ticket seemed to have trailed off into some confusion over who needs to do some testing where. I agree with Dan that that who needs to be someone with LHCB credentials! The waters still seem muddied. In progress (1/7)

IC
114737 (30/6)
The IC voms wasn't updating properly, due to what I infer from the ticket as "SSL/mysql madness". Simon and Robert have been heroically battling this one - it's a good read. On hold (3/7)

114379 (16/6)
Sam's ticket about SE support in Dirac. Sam will shortly try testing things out on the new Dirac to see how it fares. In progress (6/7)

BRUNEL
114447 (18/6)
Brunel's gridpp pilot ticket. Being worked on, with one CE with the pilots enabled. In progress (26/6)

114006 (31/5)
A ticket from APEL, about Brunel under-reporting the number of jobs they are doing. Turned out to be a problem with Arc, which Raul upgraded to the fixed 5.0 version. The APEL team deleted the sync records, but no word since. In progress (30/6)

114850 (6/7)
Another APEL ticket, likely the fallout of the previous one - it looks like GAP publishing has been left on for the Brunel CREAM CEs. Assigned (6/7)

TIER 1
114786 (2/7)
Low availability ticket - see RALPP ticket 114442 - probably could do with Ob holding. In progress (2/7)

113910 (26/5)
Sno+ data staging problems. Brian gave some advice on how the large VOs do data staging from tape, and has asked if Sno+ still has problems. Matt M might still be on leave though. Waiting for reply (23/6)

108944 (1/10/14)
CMS AAA problems, which eventually brought to light to a problem with super-hot datasets which were alleviated (I think). Despite an update to castor that improved performance the last batch of tests didn't show improved results. No news since. In progress (17/6)

113836 (20/5)
Glue mismatch problems at RAL. Working on getting "many-Arcs" to correctly publish. In progress (24/6)
