* Please can sites review their GOCDB information: https://ggus.eu/?mode=ticket_info&ticket_id=141296
* LSST: submission from panda is now working at Lancs, Manc and RAL. The plan (only sketched for now) is to run a data challenge. GridPP is behind this and said we should give a high priority to this effort. At the moment the initial plan is to use 16,000 cores for a month. This is a significant chunk of resources and will require organisation and much testing to get it running smoothly. Though using panda LSST doesn't have all the resubmission features ATLAS has, they also use the storage tools slightly differently privileging xrootd which is not as well supported as gridftp.

A reminder that there is a weekly [http://www.gridpp.ac.uk/wiki/RAL_Tier1_Experiments_Liaison_Meeting Tier-1 experiment liaison meeting]. Notes from the last meeting [https://www.gridpp.ac.uk/wiki/Tier1_Operations_Report_2017-06-28 here]

'''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 are still some issues for CMS access to Castor - these can be seen in timeouts affecting the CMS SRM SAM tests.
+
<!-- *********************************************************** ----->
* The new version of FTS3 installed on our "test" FTS service (used by Atlas) no longer supports the SOAP API. There are still some access to our "production" FTS3 service via this API (mainly SNO+ and MICE). We will wish to upgrade the production FTS3 service - and need VOs to move to the rest API provided with the newer versions of FTS. Would will set deadline when we upgrade the "production" instance and hence no longer support the SOAP API.
+
* The OPN link to CERN was upgraded to 3 * 10Gbit last Wednesday (28th June).
+
* EGI have announced withdrawal of support for the WMS at the end of 2017 (as announced elsewhere).

<!-- **********************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.

 +
* 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.

Minor change to LHCB requirements in Approved VOs:
* Please check the keydocs page. Would all owners please review their pages and prepare a short note on how they will bring things up-to-date in the coming months. This will be discussed at a core ops meeting (poll to be circulated shortly).
+
* There are several EGI operations document updates out for review. Please make comments to Jeremy by 20th Febraury for inclusion in the UK feedback:
+
** - Resource Centre OLA https://documents.egi.eu/document/31

** - Resource Infrastructure Provider OLA https://documents.egi.eu/document/463

https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs#VO_Resource_Requirements
  
The fusion VO has been removed from GridPP Approved VOs.
+
'''Tue 2nd April 2019'''
  
'''Monday 9th January'''
+
Changes to Approved for DUNE (and LZ)
  
* Tom put these together:
+
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.
** A [http://dx.doi.org/10.5281/zenodo.222702  snapshot of the GridPP UserGuide] is now available as an offline document in the Zenodo repository:
+
** ...and the v1.0 release of the LaTeX code used to compile it is [http://doi.org/10.5281/zenodo.222755 here].
+
**  There are some minor differences (mainly hyperlink-related) to the online version [1], which has also had a v1.0 release [http://doi.org/10.5281/zenodo.222756 here].  
+
  
 +
https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs
  
''' Tue 22nd Nov '''
+
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.
  
* More on Accounting audit tools
+
Sites with DUNE services need to update using whatever method they employ.
  
The process for ARC, Toque and VAC is now documented here.
+
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.

* An update from the DIRAC workshop? GridPP is still the only true multi-VO instance, so we will continue to see issues with this.  release quality of dirac has improved within the past year. gfal2/EL7 problems seem to be coming to an end after being cooped up with all authors for 3 days on end. The Imperial GridPP module now has integrated testing. It was also noted that every dirac instance has it's own special module to adapt to their community on top of main dira. We are trying to push as much of out special functionality back into the main dirac branch.

Start with a golden oldie, the Sussex webdav/xrootd ticket. No news since some promising progress a few months back. As Alessandra asks in the ticket, any news on this? In progress (9/5)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=127767 127767] (18/4)<br />

LHCB ticket regarding publishing ARC at Glasgow (aka the Cursed Ticket).

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.

  • 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 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.
