* 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 [https://ggus.eu/index.php?mode=ticket_info&ticket_id=114657&come_from=submit ticket] was raised.
 
* A preliminary draft of the [https://indico.cern.ch/event/319749/ July GDB agenda] is available.
 
* In In order to get the broadest input [http://fluidsurveys.com/s/egi-engage-mp-general-survey/ EGI has prepared a survey] (deadline July 7th).
 
* There was an EGI OMB last week. Please take a look at the [https://indico.cern.ch/event/405285/contribution/2/material/0/0.pdf 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* The camont collaboration is no longer active, but the VO is enabled and useful.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 '[http://www.comprt.org/research/ghost-project 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).

* There was a WLCG ops coordination meeting last Thursday 18th June: [https://indico.cern.ch/event/393609/ Agenda]. [https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOpsMinutes150618Minutes].
 
* 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.
 
* IPv6: NTR
 
* Network and transfers WG: PS: proposed mesh for upto 100 sites. Potential bug noted. Next meeting 8th July.
 
* HTTP: 2nd meeting on 3rd June. [https://twiki.cern.ch/twiki/bin/view/LCG/HTTPTFStorageRecommendations Draft conclusions]. Next meeting 15th July.
 
  
'''Tuesday 16th June'''
 
* The next WLCG ops coordination meeting is this Thursday 18th June: [https://indico.cern.ch/event/393609/ Agenda]. There will be presentations and discussions on the Information System.
 
* The next middleware readiness meeting is on Wednesday 17th June @ 3pm BST: [http://indico.cern.ch/event/393222/ Agenda].

'''17 June 2019''' Report for the Experiments Liaison Report (17/06/2019) is [https://www.gridpp.ac.uk/wiki/Tier1_Operations_Report_2019-06-17 here].
* There were two separate network-related problems on Tuesday afternoon last week. The first was a short (less than ten minute) break in connectivity when a router rebooted. The second, which lasted around 45 minutes, was a period of very high traffic caused by an operational/configuration problem on a hypervisor.
+
<!-- *********************************************************** ----->
* We have announced an 'at risk' for the next quarterly UPS/generator load test tomorrow (Wednesday) morning.
+
 
<!-- **********************End T1 text************************** ----->
 
<!-- **********************End T1 text************************** ----->
 +
* Ongoing, we are seeing high outbound packet loss over IPv6.  Central networking performed a firmware update to the border routers but this didn’t resolve the issue.  Plan to move connections to the new border routers in Mid June.  Will do this before trying to debug any further.
 +
 +
'''11 June 2019''' Report for the Experiments Liaison Report (10/06/2019) is [https://www.gridpp.ac.uk/wiki/Tier1_Operations_Report_2019-06-10 here].

 +
* Three certificates were revoked mistakenly on ARGUS on Thursday.  All SAM tests failed until this was fixed the next morning.  Batch farm also did not start any new jobs during this time.  We used this accidental draining to reboot nodes that needed to pick up security patching.
 +
* LHCb Castor instance has been completely disabled for LHCb and will be decommissioned.
 +
* Brian Davies has transferred from his role as GridPP Tier-2 Storage Support Officer and has joined the Tier-1 Production Team.  Although this has happened with immediate effect he will still be available for ad-hoc/informal storage support.

+
  
'''Wednesday 27 May'''
+
'''[http://storage.esc.rl.ac.uk/weekly/20191002-minutes.txt Wed 02 Oct]'''
* Working on troubleshooting DIRAC data for/with LIGO (not to be confused with DiRAC or with any of the other things called DiRAC)
+
* Safe to upgrade to DPM 1.13 but make sure the BDII is working if you support DIRAC
* Working on setting up DiRAC at Tier 1 (not to be confused with DIRAC or Dirac or with any other thing called Dirac)
+
* Roadmap for xroot and http TPC for RAL FTS(es)
* New secret user support list!
+
  
'''Tuesday 18th May'''
+
'''[http://storage.esc.rl.ac.uk/weekly/20190925-minutes.txt Wed 25 Sept]'''
* [http://storage.esc.rl.ac.uk/weekly/ Minutes are available.]  
+
* Storage support for IRIS VOs?
  
'''Tuesday 21st April'''
+
'''[http://storage.esc.rl.ac.uk/weekly/20190918-minutes.txt Wed 18 Sept]'''
* Has there been any Tier-1 contact with DiRAC?
+
* Report from yesterday's Rucio Face Meeting at Coseners
* Proposal to setup an 'other VOs' users list. GridPP-Users is too tied with WLCG projects.
+
* Suggestions for following up from yesterday's CEPH day hosted by CERN
 +
 
 +
'''[http://storage.esc.rl.ac.uk/weekly/20190911-minutes.txt Wed 11 Sept]'''
 +

 +
* DOME upgrade tickets for non-DOME DPM sites
 +
 
 +
'''[http://storage.esc.rl.ac.uk/weekly/20190904-minutes.txt Wed 04 Sept]'''
 +
* Banning in SSC not entirely successful in non-DOME DPM, and end of support is nigh; tickets to upgrade will go out shortly.
 +
* Storage-and-data-management-wise, GridPP43 was interesting although no-one volunteered to install the next CEPH.
  
'''[http://storage.esc.rl.ac.uk/weekly/20150415-minutes.txt Wednesday 15 April]'''
 
* Backing up data from [http://www.stfc.ac.uk/1263.aspx 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.

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.

* Next LHCOPN and LHCONE meeting: [https://indico.cern.ch/event/772031/ Umeå, Sweden, 4-5 Jun 2019]. Registration required.  
** ...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.

+
32 Open Tickets this week, which is an in depth a look as I've been able to take.
Things look generally alright - but Durham look like they need to update their CA rpms - but that might have to wait until Oliver is back from leave.
+
 
+
'''Tarballs:'''<br />
+
I don't think this effects many, but there's was a ticket to produce a new version of the WN tarball (which is done): [https://ggus.eu/index.php?mode=ticket_info&ticket_id=114574 114574]<br >
+
Although AFAICS there is no urgent need to upgrade tarball WNs.
+
 
+
26 UK Tickets, although not many stand out.
+
 
+
'''Gridpp VO Pilot tickets:'''<br />
+
Largely doing alright. With Oliver away the Durham ticket hasn't been looked at yet. Sheffield and Bristol's tickets could do with an update (or on-holding if there's going to be a delay). The RHUL ticket has been reopened as they're deployment of the pilot roles hasn't quite worked out.
+
 
+
'''QMUL'''<br />
+
[https://ggus.eu/?mode=ticket_info&ticket_id=114573 114573] (23/6)<br />
+
LHCB having trouble with two out of three QM CEs. Dan notes that the two "broken" CEs have been recently dual-stacked, and asks if this could be the problem. The answers is a resounding "maybe", and Raja asks if problems could be duplicated by others using lxplus. Waiting for reply (24/6)
+
 
+
'''IMPERIAL/DIRAC'''<br />
+
[https://ggus.eu/?mode=ticket_info&ticket_id=114379 114379] (16/6)<br />
+
Sam's ticket trying to get SE support with Dirac...er, spruced up. Daniela has asked if the tests can be redone with the "new" dirac. Waiting for reply (22/6)
+

Let me know if I missed any tickets.

  • I got stuck (figuratively) in my machine room last Thursday afternoon so missed it. Agenda. Minutes. Ste was there - any observations?

Tuesday 14th May

  • Next meeting this Thursday.

Tuesday 9th April

Monday 11th February 2019

  • There was a WLCG ops coordination meeting last Thursday. You can view the meeting notes here.
    • End of CREAM support Dec 2020.
    • Migration from CREAM to be discussed at the EGI conference 6-8 of May in Amsterdam.
    • Operational intelligence discussion (see slides).
    • Experiment updates (see ATLAS discussion on DOMA)
    • WG updates (few).




Tier-1 - Status Page

17 June 2019 Report for the Experiments Liaison Report (17/06/2019) is here.

  • Ongoing, we are seeing high outbound packet loss over IPv6. Central networking performed a firmware update to the border routers but this didn’t resolve the issue. Plan to move connections to the new border routers in Mid June. Will do this before trying to debug any further.

11 June 2019 Report for the Experiments Liaison Report (10/06/2019) is here.

  • Ongoing, we are seeing high outbound packet loss over IPv6. Central networking performed a firmware update to the border routers but this didn’t resolve the issue. Plan to move connections to the new border routers in Mid June. Will do this before trying to debug any further.
  • Three certificates were revoked mistakenly on ARGUS on Thursday. All SAM tests failed until this was fixed the next morning. Batch farm also did not start any new jobs during this time. We used this accidental draining to reboot nodes that needed to pick up security patching.
  • LHCb Castor instance has been completely disabled for LHCb and will be decommissioned.
  • Brian Davies has transferred from his role as GridPP Tier-2 Storage Support Officer and has joined the Tier-1 Production Team. Although this has happened with immediate effect he will still be available for ad-hoc/informal storage support.

Monday 14th November

  • Alessandra has written an FAQ to extract numbers from ATLAS and APEL avoiding the SSB.

Monday 26th September

  • A problem with the APEL Pub and Sync tests developed last Tuesday and was resolved on Wednesday. This had a temporary impact on the accounting portal.
Documentation - KeyDocs

Tue 9th July 2019

LHCb has added this to their requirements:

Sites not having an SRM installation must provide:

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.
