'''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].
* Tier-1 has been very much business as usual this week.  The only incident of real note was the loss of an Atlas server(gdss747 - d1t0). This incident involved a lost drive that was found to be not recoverable.  Subsequently a data loss declared.  Under normal circumstances this would be considered a serious incident, however Atlas are all but complete in the process of migrating from CASTOR to ECHO.  As such, no primary data had been lost with 89% of lost data comprising log files.
+
<!-- *********************************************************** ----->
* Worker nodes and CONDOR are now running new Docker containers running Singularity. Further changes include an update to use UMD4. This new container is currently being tested and is running on arc-ce04.
+
* The new Docker container image (stfc/grid-workernode-c6:2018-07-09.2 and stfc/grid-workernode-c7:2018-07-09.2), has been rolled out across the entire batch farm.

* 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.

''' Tue 9th July 2019'''
  
Steve Jones is updating the User Guide with various mods that have cropped up since Tom Whyntie left (pending permission to edit GridPP website docs...)
+
LHCb has added this to their requirements:
  
'''Tuesday 11th June 2018'''
+
Sites not having an SRM installation must provide:
  
Approved VOs now contains two new SKA VOMS servers (at Oxford and Imperial, as well as Manchester).
+
* disk only storage
 +
* a GRIDFPT endpoint (a single dns entry)
 +
* an XROOT endpoint (a single dns entry)
 +
* a way to do the accounting (preferably following the WLCG TF standard: https://twiki.cern.ch/twiki/bin/view/LCG/StorageSpaceAccounting)
  
 +
''' 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.

 +

 +
 +
'''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.

Tuesday 4th June 2019


WLCG Operations Coordination - AgendasWiki Page

Tuesday 11th June

  • 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


Tuesday 26th March

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.
Storage & Data Management - Agendas/Minutes

Wed 30 Oct

  • DOME upgrade problems at Edinburgh
  • Data management support/development for IRIS users

Wed 23 Oct

  • Rucio reporting

Wed 16 Oct

  • CEPH workshop at CERN report

Wed 02 Oct

  • Safe to upgrade to DPM 1.13 but make sure the BDII is working if you support DIRAC
  • Roadmap for xroot and http TPC for RAL FTS(es)

Wed 25 Sept

  • Storage support for IRIS VOs?

Wed 18 Sept

  • Report from yesterday's Rucio Face Meeting at Coseners
  • Suggestions for following up from yesterday's CEPH day hosted by CERN

Wed 11 Sept

  • Storage related stuff at the FNAL (pre-)GDBs
  • DOME upgrade tickets for non-DOME DPM sites

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.


Tier-2 Evolution - GridPP JIRA

Tuesday 30 Apr 2019

  • ATLAS CernVM4 VMs (equivalent to CentOS 7.6) being tested


Accounting - UK Grid Metrics HEPSPEC06 Atlas Dashboard HS06

Tuesday 24th Oct


Monday 16th January

  • The discussion topic for next week will be accounting comparisons. Please note Alessandra's comments last week.

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.
