'''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 was a problem with the LFC service. A new node was added to the alias but it was not configured to support dteam VO. This was corrected in response to a GGUS ticket.
+
<!-- *********************************************************** ----->
* A better understanding of CEPH problems with Echo has provided stability. However, careful management of the disks in servers recently added into Echo has been needed. This has slowed the rate at which the new hardware is being brought into full use.

* 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.

* Safari on macOS autogenerated client certificates fix put into production last week.
+
  
'''Tuesday 19th Sept 2017'''
+
LHCb has added this to their requirements:
* Bug in Safari on macOS causes random Apple generated client cert to be presented to www.gridpp.ac.uk using a CA we don't know about. The connection is then rejected by Apache. Other browsers ok since we request but do not require that they supply a certificate. Workaround produced by (a) installing the Apple CA root and intermediary CA and (b) whitelisting UK e-Science DNs (+ CERN? Others?) in the HTTPS Wiki plugin. Tested but not yet in production.

'''Tuesday 5th Sept 2017'''
+
Sites not having an SRM installation must provide:
  
New Approved VO. SKA European regional data centre, skatelescope.eu
+
* disk only storage
 +
* a GRIDFPT endpoint (a single dns entry)
 +
* an XROOT endpoint (a single dns entry)

''' Tue 16th April 2019'''
  
This VO is ramping up and has requested support. Andrew McNab is the contact person for GridPP.

Minor change to LHCB requirements in Approved VOs:
  
'''Tuesday 25th July'''
+
* Sites having migrated to the Centos7 (including "Cern Centos7") operating system or  later versions are requested to provide support for singularity containers.
  
London grid (vo.londongrid.ac.uk) VO removed from Approved VOs.

 +
'''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.

* 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.

'''RALPP'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=130264 130264] (28/8)<br />

'''OXFORD'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=130032 130032] (11/8)<br />
 
LHCB jobs failing on upload. The ticket occurred at a time of multiple SE troubles, and there's not been any news throughout September so first port of call will be to see if the problems persist. In progress (23/8)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=130173 130173] (22/8)<br />
 
A ticket from Duncan about incomplete perfsonar results, with the likely solution being to reinstall to CentOS7. Kashif is on it. In progress (26/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=129931 129931] (4/8)<br />
 
http SAM tests failing - for unknown reasons. Kashif hopes an update of the headnode will fix things. On hold (19/9)
 
 
'''CAMBRIDGE'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=130787 130787] (28/9)<br />
 
LHCB pilots failing at Cambridge. It looks like lhcb jobs are failing due to hitting a CPU time limit, although no changes have been made site side to break things. John proposed increasing the CPU limits. Waiting for reply (28/9)
 
 
'''BRISTOL'''<br />
 
[https://ggus.eu/?mode=ticket_info&ticket_id=130646 130646] (20/9)<br />

[https://ggus.eu/?mode=ticket_info&ticket_id=130202 130202] (24/8)<br />
 
Not really a IC ticket, but one to all na62 sites - about na62 jobs waiting too long. Dan included a useful [https://na62.gla.ac.uk/index.php?task=stats&view=sitehealth link] in the ticket - there's feedback from RAL in the ticket too. Is it just fairshare (fairly) stopping na62 jobs running as quickly as they'd like? In progress (27/9)

32 Open Tickets this week, which is an in depth a look as I've been able to take.
CMS SAM tests failing at RAL, due to a lack of space on CASTOR. Chris has identified a bunch of dark data and set about purging it, ready for another round of consistency checks. In Progress (25/9)
+
  
[https://ggus.eu/?mode=ticket_info&ticket_id=130782 130782] (27/9)<br />
 
A request from lhcb to deploy the latest version of heposlibs (which contains a dependency on git). The request has been passed along at the Tier 1. In progress (28/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=130193 130193] (23/8)<br />
 
CMS staging of files taking a too long from RAL tape- possibly due to a bunch of corrupt files (although manual copies for some problem files are working). George has asked CMS to try again, and if problems persist send a list of dodgy files. Waiting for reply (29/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=130207 130207] (24/8)<br />
 
MICE seeing timeouts copying to CASTOR. Gareth provided an indepth update in the ticket, the ticket is being kept open whilst the GenTape disk pool is upgraded. In progress (6/9)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=127597 127597] (7/4)<br />
 
A CMS ticket to check networking and xroot performance, held up for a while waiting on the RAL networking team. There is some recent movement to repoke the networkers. On hold (2/10)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=124876 124876] (7/11/16)<br />
 
ECHO SAM tests failing due to a problem with the tests - no movement on the counter-ticket ([https://ggus.eu/?mode=ticket_info&ticket_id=125026 125026]) since April - it likely needs a kick. On hold (1/1)
 
 
[https://ggus.eu/?mode=ticket_info&ticket_id=117683 117683] (18/11/15)<br />
 
Getting GLUE 2 working for CASTOR. Intermittently worked on as time allows. The ticket could do with an update this quarter. On hold (6/7)

  • 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.
