  • Anyone have anything else?


Tuesday 12th March 2019


Tuesday 5th March 2019


Monday 18th February 2019


Tuesday 12th February

  • DPM release - 1.11
  • Approved VOs: changes to BIOMED and ENMR
  • Simon: VAC with VM condor VM to support local batch jobs?
  • There is a GDB this week - agenda.
  • NGI Argus/Central Banning config (see DC message).
  • There was a WLCG ops meeting yesterday. Minutes are available.
  • HOW19 registration (early bird rate has ended). HSF-OSG-WLCG joint workshop.
  • A/R explanations for January: QMUL power outage; Bham now on EOS so SE tests fail; ECDF 80% LHCb??


Tuesday 5th February

  • The EGI RP/RC A/R Report for January 2019 is available. UKI overall fine. Bham and RAL-LCG2 may wish to examine their results.
  • A reminder.... Please could everyone think about their WLCG (and beyond) engagements and commitments and put anything of note in the wiki table here.
  • Notes from yesterday's WLCG ops meeting are available. Issues at RAL noted by LHCb.
  • It is CMS week this week.
  • In case missed here is Elena's ATLAS update:
    • https://ggus.eu/index.php?mode=ticket_info&ticket_id=138033: singularity jobs failing at RAL. A job that Alessandra submitted still has a problem with the home directory. Ral is trying to fix it.
    • There was a power lost to a rack and the two storage nodes in it in Lancaster over weekend which cause a problem to ATLAS jobs. This was fixed on Monday.
    • Raul asked for srmless atlas transfers for Brunel. Elena is changing transfer configuration in AGIS but the jobs are still failing. Peter will look into this.
    • There was a discussion on lightweight ATLAS Grid sites @ADC weekly last week. Sheffield, Cambridge, Brunel, Durham, Bham and Sussex should become diskless sites.
  • There is an ongoing discussion about LSST jobs on GridPP resources that may be of wider interest. Their VOMS was down so the question was raised about using GridPP VOMS or setting up another VOMS in the UK to read its data from the SLAC instance.
  • The 9th DIRAC Users Workshop will be held in London 14. - 17. May 2019. Here is the registration link.
  • December's WLCG A/R final report is available at via this link.
  • The figures for January 2019 are now available and updates from 3 sites requested:
  • Simon G asks: VAC with VM condor VM to support local batch jobs? Has anyone done it??
  • EGI has started an HTCondor integration process and captures progress here: https://ggus.eu/index.php?mode=ticket_info&ticket_id=139377.
  • End of Support for CREAM-CE: The CREAM working group has announced that official support for the CREAM-CE component will cease at the end of the EOSC-hub project, i.e. in Dec 2020. The CREAM working group will be providing full support until the end of 2019, including one minor release already scheduled. During 2020 only security updates will be released.

Documentation - KeyDocs

Tue 16th April 2019

Minor change to LHCB requirements in Approved VOs:

  • Sites having migrated to the Centos7 (including "Cern Centos7") operating system or later versions are requested to provide support for singularity containers.

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

Tue 2nd April 2019

Changes to Approved for DUNE (and LZ)

There is a new "Approved VOs" document showing new settings for DUNE. And, since both LZ's voms servers now show up in the EGI Portal, I've removed the (now spurious) entry for voms.hep.wisc.edu that was formerly being inserted by hand.

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

I've also created a new set of RPMs (each has all LSC, VOMS, and XML for one VO) for all approved VOs. See Approved VOs doc for details, version is 1.9.

Sites with DUNE services need to update using whatever method they employ.

Special note: Since voms1.fnal.gov changed yesterday, I've updated documentation for that right away. But voms2.fnal.gov remains as it is until 23rd April (3 weeks). I'll update documentation for that when it is closer. Staggering the updates like this gives a time margin, so any particular site can have at least one service properly configured at any time. But it does mean that two site updates are needed; one now, and one in three weeks. However, since it's sufficient for only one (of the two) voms servers to be configured properly, sites could save effort and wait until (say) 19th April, then update both at once. But I can't dictate what site admins should do. It's your call.

Tickets

Monday 13th May 2019, 14.00 BST
37 Open UK Tickets this month.

IPv6 Tickets
Oxford: 131615 On Hold (13/3)
This ticket could likely do with a progress update once you jump under the DOME.

Birmingham: 131612 In Progress (5/2)
How goes things with the v6 DNS? The ticket could do with an update, or if you're not having much joy perhaps being set back to "On Hold".

Glasgow: 131611 In Progress (5/2)
I suspect this ticket should be put On Hold until the big move?

Durham: 131609 On Hold (4/12/18)
This ticket could do with an update (even a null one).

Manchester: 131607 In Progress (9/4)
There's light at the end of the v6 tunnel for Manchester, did you roll deploying this into last week's work?

Liverpool: 131606 On Hold (6/2)
Another ticket that could do with an update, even if it's just to fill the silence.

RHUL: 131603 In Progress (8/4)
Simon and Tony have been poking their network manager but no joy in getting the paperwork to use the JANET services signed off. Anything we can do?

Sheffield: 131608 On Hold (7/5)
Elena has layed out the Sheffield plan - with the SE on the way out this year it's not going to be dual-stacked, and a plan to reinstall their perfsonars next month (dual-stacked?).

The rest of the tickets...

BIRMINGHAM
140679 (10/4)
Ticket tracking the decommissioning of the Birmingham CREAM CE. I believe things have progressed further then are reflected in the ticket? But in general there doesn't seem to be any big uproar over switching it off (yet). In progress (29/4)

OXFORD
141099 (9/5)
A DUNE ticket about jobs not working, it looks like a classic problem of wrong voms settings and DUNE jobs are running now, so maybe this ticket can be closed. Waiting for reply (13/5)

GLASGOW
141124 (10/5)
Atlas analysis jobs not running properly at Glasgow. Gareth as on held the ticket until AC problems at the site are fixed, to see if that solves the issue as well. On Hold (13/5)

140222 (15/3)
MICE DFC migration ticket. I think the conversation has stalled, last update was from Daniela asking if a user was still a user, and if their data can be purged or not. In progress (10/4)

ECDF
140802 (22/4)
LHCB Pilots aborting at ECDF. This seems to come and go in cycles - any joy in figuring out what the underlying issues are? I assume you're waiting to see if all is okay after your recent downtime. In progress (26/4)

141098 (9/5)
Another DUNE ticket (they've found their voice!). Teng has confirmed that ECDF is in a "let's wait and see if it's all working now" period. On Hold (10/5)

140846 (24/4)
ROD ticket for the ECDF CE, a symptom of all the badness that the site's been experiencing. A quick check shows that ce8 is looking fairly green in nagios. In Progress (29/4)

DURHAM
141104 (10/5)
Multiple ROD alarms at the site. Adam was investigating, but things look okayish now. In Progress (10/5)

SHEFFIELD
141134 (12/5)
Atlas transfer failures due to what looks like an expired cert. In progress (12/5)

140866 (25/4)
Biomed jobs failing with what look like authentication errors. Any joy/time in looking at this? In progress (25/4)

140987 (2/5)
Another DUNE ticket. A number of small showstoppers have been fixed, so hopefully DUNE jobs are running at Sheffield now? Waiting for reply (10/5)

138649 (3/12/18)
(The last) T2K migration ticket. Elena has it in her schedule, but her plate is full. Hopefully tomorrow. On Hold (13/5)

LIVERPOOL
139411 (30/1)
A Biomed ticket from Biomed asking if using the BIOMEDDISK spacetoken could be made automagic. John explained the situation, what's the plan with this ticket. Keep it open until you're DOME'd? You could close it as the initial question has been answered. On Hold (1/2)

UCL
139101 (8/1)
Any joy getting ViaB working at UCL? In Progress (8/4)

QMUL
141133 (12/5)
LHCB FTS transfer problems. Terry reports power problems at the site, with no news when juice will be restored. Hopefully soon! On Hold (13/5)

141132 (12/5)
Atlas issues for the same reason. The atlas response was quite harsh though. In Progress (13/5)

140190 (14/3)
The old LHCB FTS ticket, left on hold whilst things are investigated in the event problems crop up again. On Hold (23/4)

138364 (19/11/18)
T2K DFC migration ticket - it's all in the VO's hands now and Daniela proposes closing the ticket. In progress (13/5)

134573 (17/4/18)
CMS request to install singularity. I'll ask you how it's going at a later date. On Hold (5/11/18)

BRUNEL
140669 (10/4)
LHCB job failures, by the looks of it on a pair of v6-only WNs. I'm not sure how things are going, but the ticket is being actively investigated on both sides. In Progress (9/5)

IMPERIAL MASTER TICKETS
138359 -T2K DFC migration
140198 -MICE DFC migration

TIER 1
141108(10/5)
DUNE having problems submitting to the Tier 1. Any joy? In Progress (10/5)

140870 (25/4)
T2K spotted a number of files that should be on type according to the DFC aren't. After a bit of digging it seems that the files simply weren't moved to their correct (according to the DFC) places yet. How goes the move? In Progress (29/4)

140773 (18/4)
LHCB ticket over slow ECHO deletions. Investigating thoroughly, spotting a possible issue with gridftp session reuse. Trying to replicate the issue elsewhere. In progress (8/5)

141105 (10/5)
ROD SRM failures. George notes a problem with the castor certs that are being fixed. In progress (10/5)

140220 (15/3)
MICE DFC migration ticket. The last update had some questions from Daniela to both the CASTOR admins and MICE - neither of which have had a reply in the ticket. In progress (8/4)

140447 (27/3)
Duncan spotted outbound v6 packet loss from the Tier 1. Brian confirms that only v6 is affected, and there is a plan to upgrade the firmware in the border router (I think that's what the plans are?). Hopefully that will get it. On Hold (10/5)

139672 (13/2)
LIGO pilots not running at RAL. Did Catalin get his LIGO membership reinstated for debugging purposes? In progress (30/4)
