Week commencing 13th July 2015
Task Areas
General updates

Tuesday 14th July

  • There was a GDB at CERN last Wednesday agenda: minutes.
  • Very worthwhile reviewing Romain's talk from the GDB on threats.
  • Raja noted: It looks like some certificates have problems when submitted to CEs with RHEL5 variant OS-es underneath. Does this need further investigation/work?
  • Matt: reports that the EMI WN tarball now contains gfal CLI utilities.


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.


WLCG Operations Coordination - Agendas

Tuesday 14th July

  • There is a fortnightly WLCG Operations Coordination meeting this Thursday, July 16th at 3:30pm CEST. There will be a presentation proposing a new Task Force studying the future of the Information System.


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

Storage & Data Management - Agendas/Minutes

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

Accounting - UK Grid Metrics HEPSPEC06 Atlas Dashboard HS06

Tuesday 14th July

  • QMUL and Sheffield appear to be lagging with publishing by a week.
  • Please check your multicore publishing status (especially those sites mentioned in June).

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

    • t2ce06.physics.ox.ac.uk

Tuesday 9th June

  • Delay noted for Sheffield


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 13th July

  • SR updates (small because it's summer):
      • gfal2 2.9.1
      • storm 1.11.9
      • srm-ifce 1.23.1....
      • gfal2-python 1.8.1
    • In Verification
      • gfal2-plugin-xrootd 0.3.4
  • Accounting
    • [John Gordon] "Of the WLCG sites we now have 97%+ of cpu reported with cores. I expect you all saw my recent email to GDB naming 16 sites. If one German and one Spanish site and the four Russians start publishing we will jump to 99%+"
    • New list of sites needing to update multicore accounting being prepared this evening (Monday) by Vincenzo
  • SL5 decommissioning date March 2016;
  • Next meeting 10th August

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.


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 13th July

  • Quiet week, once the (unofficial) ARC fix was implemented on the nagios side.
  • Low/best efforts ROD effort after this week for 1-2 weeks.

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 13th July

  • EGI SVG/CSIRT **Update** OpenSSL release on 9th July - CVE-2015-1793

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 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.

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

Tuesday 14th July 2015, 9.30 BST

Lazy update today, due to some fun and games at Lancaster yesterday.

UK GGUS Tickets

Other VO Nagios

Tickets that pop:

114952 and 114951 are both atlas frontier tickets at RALPP and Oxford, both have been reopened - although the underlying issues seem different. The Oxford ticket is similar to one at RAL (114957), which looks to be caused by an unannounced change in IP for some important atlas squids (AIUI - speed reading the tickets this morning).

QM IPv6 Woes
Followers of the atlas uk lists will have noticed some heroic attempts to diagnose and repair problems at QM which appear to be someone else's fault. LHCB's ticket to QM on the matter: 114573
Dan's ticket concerning the "rogue routes": 115017

GridPP Pilot Roles
Durham, Bristol, Sheffield, Brunel and RHUL still have open tickets about this. Bristol are working on it, as are Durham - Oliver's ready for their setup to be tested again (Puppet overwrote his last changes!). Not much recent news from the other three.

That's all from me folks, let me know if I missed ought!

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/


VOs - GridPP VOMS VO IDs Approved VO table

Tuesday 19th May

  • There is a current priority for enabling/supporting our joining communities.
