 +
* 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 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.

−
 
−
'''LANCASTER'''<br />
 
−
[https://ggus.eu/?mode=ticket_info&ticket_id=136635 136635] (9/8)<br />
 
−
Lancaster is having no luck shifting this availability alarm due to SRM CertLifetime checks erroring constantly, causing 100% "Unknown" status. Has anyone seen this before? Could we blag that it's a problem with the check? On hold (8/10)
 
−
 
−
'''TIER 1'''<br />
 
−
[https://ggus.eu/?mode=ticket_info&ticket_id=137195 137195] (14/9)<br />

Any luck fixing the Castor LDIFs to clear these ROD alarms? (I don't seem to have permission to check the links to the tests myself). In progress (10/10)
 
−
 
−
[https://ggus.eu/?mode=ticket_info&ticket_id=136199 136199] (18/7)<br />

−
'''IPv6 Tickets'''<br />

(with reference to [https://www.gridpp.ac.uk/wiki/IPv6_site_status the IPv6 site status table])
 
−
 
−
'''RALPP:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131616 131616] <br />
 
−
No update for a long while on either the ticket or the table after some promising progress. In Progress (31/1)
 
−
 
−
'''OXFORD:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131615 131615] <br />
 
−
Last update on the ticket back in July describes v6 as the blocker, is this still the case? On Hold (13/7)
 
−
 
−
'''CAMBRIDGE:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131614 131614]<br />
 
−
Some nice progress with the site perfsonar boxen dual-stacked. The table is also up to date. Nice. In progress (8/10)
 
−
 
−
'''BRISTOL:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131613 131613]<br />
 
−
Some recent discussion with CMS and Duncan, xroot works for v6 but srm/gridftp doesn't. I think steps have been made to fix this (from an entry in the table) but I'm not sure what they were! In progress (11/10)
 
−
 
−
'''BIRMINGHAM:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131612 131612]<br />
 
−
Mark's update back in August painted a familiar picture of central IT dragging their heels. As ALICE consider v6 a necessary thing Mark has been asked to keep up the pressure. No recent update on the table. On hold (27/8)
 
−
 
−
'''GLASGOW:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131611 131611]<br />
 
−
Some good progress here, with some v6-ining (or dual-stacking) of the perfsonar boxes and a hope to be able to dual-stack the storage by the end of the year. Duncan spotted a few problems (that might be ip6table related), but I understand Gareth was off last week. The table entry is up to date too, sterling stuff.  In progress (12/10)
 
−
 
−
'''EDINBURGH:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131610 131610]<br />
 
−
Dual-stacking has caused a lot of interesting times at ECDF. Rob gave a good update on their situation last month, and the table is up to date. Interesting that v6 traffic won't go through the JANET link for the site (it must have at one point, right?). Any recent news about dual-stacking your disk nodes? In Progress (10/9)
 
−
 
−
'''DURHAM:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131609 131609]<br />
 
−
Adam provided an update last week, with (again) reverse IPv6 DNS being a sticking point (despite v6 traffic otherwise flowing fine). Adam's expected timeframe for being able to do a full v6 rollout is mid-2019. Whilst it's depressing it's good to know this ahead of time. No update on the table since 2015 though, but looking at the last entry there you could just change the date. In progress (should be on hold?) (17/10)
 
−
 
−
'''SHEFFIELD:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131608 131608]<br />
 
−
Things looked a bit hopeful with work in this area (re-)scheduled to start in July, but it looks like thing stalled. Any news? The table mirrors the last update. On hold (10/7)
 
−
 
−
'''MANCHESTER:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131607 131607]<br />
 
−
The perfsonars are dual-stacked but IIUI v6 reverse DNS is again the sticking point that prevents dual-stacking the storage. The table entry is more up to date then the ticket. On hold (25/4)
 
−
 
−
'''LIVERPOOL:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131606 131606]<br />
 
−
The Liver-admins were waiting on new routers needed to sort out the site's v6 problems back in June. Any news at all since? Bad news is better then no news in this case. In progress (On hold it?) (4/6)
 
−
 
−
'''UCL:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131604 131604]<br />
 
−
An update today that Ben is hoping to reinstall and dual-stack their perfsonar this week. As they have no storage that will be them sorted if it all goes to plan. In progress (22/10)
 
  
−
'''RHUL:''' [https://ggus.eu/?mode=ticket_info&ticket_id=131603 131603]<br />
+
32 Open Tickets this week, which is an in depth a look as I've been able to take.
−
Perfsonars are dual-stacked, but the v6 reverse lookup is a problem again which is a problem for storage. Table and ticket are up to date, but has this work been properly handed over to Antonio and Simon? In progress (10/9)

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.

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.
