* The majority of T1 sites and VOs confirmed that they do use SAM tests from the critical profiles and regularly check A/R reports.
 
Suggestions for improvements:
 
** Propose policy for accepting A/R recalculation requests. The draft should be reviewed at the next meeting.
 
** VO should have flexibility in the definition of the critical profile. Though the impact of the changes in the critical profile should be carefully tested by the VO and should be announced in advance to the sites, no approval of the MB is required.
 
** Make tests as close as possible to the real production flow. ATLAS is planning some work in this direction.
 
** The proposal to include real production flows in the critical profile was not supported.
 
** Sites which do have local fabric monitoring like Nagios for example, are recommended to use an API to import test results into the local fabric monitoring. **This would help to avoid test failures staying unnoticed for months.
 
** Transparent navigation from the SAM UI to the log files is required to facilitate test failure debugging. This feature has to be preserved in the new SAM UI being developed by the monitoring team.

'''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].
* The Castor intervention scheduled for 1st March that was cancelled owing to staff availability in the poor weather has been re-scheduled for Tuesday 27th March.
+
<!-- *********************************************************** ----->
* There was a problem with xrootd access to our services that resulted in a number of GGUS tickets arriving. This was found to be an unexpected loss of a firewall rule and consequently packets being dropped. Once identified (on Tuesday 20th) the rule was been re-instated and the problem solved.
+
* CMS will be migrating data from Castor to Echo with this expected to start in a few weeks time.
+
* The problems with data flows through the site firewall being restricted is still present. New firewall equipment has been delivered and is scheduled for installation in a few weeks time.
+
 
<!-- **********************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.

 +
* 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.

The DTEAM VO has now changed its VOMS server. Please see alert notice here:
+
LHCb has added this to their requirements:
https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs

Sites not having an SRM installation must provide:
  
'''Tuesday 22nd Jan 2018'''
+
* 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)
  
CHANGE TO APPROVED VOs
+
''' Tue 16th April 2019'''
**********************
+
  
* New Approved VO
+
Minor change to LHCB requirements in Approved VOs:
  
A VO, solidexperiment.org, has been included in the GridPP Approved VOs document. Sites are requested to support this experiment, resources permitting.
+
* 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#Approved_Local_VOs
+
https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs#VO_Resource_Requirements
  
* In the Ops Portal, LHCb mentions a new cvmfs mount, /cvmfs/lhcb-condb.cern.ch
+
'''Tue 2nd April 2019'''
  
* A voms server for magic, voms02.pic.es, has an updated DN.
+
Changes to Approved for DUNE (and LZ)
  
'''Tuesday 9th Jan 2018'''
+
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.
Changes to Approved VOs.
+
  
a) VOMS servers for planck, ipv6.hepix.org and enmr are now restored to as they were before the flooding at CNAF.
+
https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs
b) The DN of a VOMS server for magic has changed.
+
  
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.
  
'''Tuesday 5th Sept 2017'''
+
Sites with DUNE services need to update using whatever method they employ.
  
New Approved VO. SKA European regional data centre, skatelescope.eu
+
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.

  • 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.

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.
