WLCG Operations Coordination - AgendasWiki Page

Tuesday 23rd January

  • There was a WLCG ops coordination meeting on 18th January.
  • Theere was a theme of SAM tests and their use in WLCG reporting. The short summary is that there is overwhelming support for use of SAM tests for operational benefits but there is often a gap between the SAM reports and experiment perceptions of site performance. One major concern was the effort required to recompute results given the number of requests where sites are trying to show even small improvements in their performance to their management/funders. A more useful measure would include a reference to job accounting. A proposal will be made to the MB. GridPP may make a statement to the WLCG MB regarding our management use.

Tuesday 21st November

  • The next WLCG ops coordination meeting will be on 7th December. Do we have any topics we would like covered?

Tuesday 7th November

  • The WLCG ops coordination meeting last week (agenda | minutes had as highlights the topics:
    • Security Operations Center WG Workshop/Hackathon
    • Review of EL7 migration plans
    • Providing reliable storage: presentation by BNL


Monday 23rd October

  • The next WLCG ops coordination meeting will be on 2nd November.

Tuesday 10th October

  • There was an ops coordination meeting last Thursday 5th October: Agenda | Minutes.
    • There is one action for us to follow-up: "Collect plans from sites to move to EL7". We could make use of the Batch Systems table.


Tier-1 - Status Page

Tuesday 16th January Report from the last Tier1 - Experiments Liaison Meeting at on 10th January is here.

  • Ongoing patching for latest security issues.
  • We had announced the decommissioning of our WMS service. This was brought forward. The WMS service had no jobs in it and would have needed patching. It was set into drain mode so as to stop accepting any new data on Wednesday 10th Jan.
  • Disk server gdss745 (AtlasDataDisk - D1T0) has failed with loss of all data on the server. The problem was triggered by a failed drive. However, errors seen on other disk drives while this one was rebuilding led to loss of the RAID6 array. There were around 960,000 files on the server - around half of which were unique. A post mortem investigation of this incident will be carried out.
Storage & Data Management - Agendas/Minutes

Wed 06 Dec

  • Another success story - CERN@School running machine learning at QMUL
  • Technical events coming up - hepsysman and cloud workshop at Crick. We ought to do something Useful or Interesting.

Wed 15 Nov

  • More xcache progress at some sites; less at others who may be blocking on dependencies or be busy with Other Things(tm)
  • Some interest in following the non-X.509 authentication/authorisation

Wed 08 Nov

  • Not (very) modest at all progress on xcache testing... from Chris at RALPP

Wed 01 Nov

  • (very) modest progress on xcache testing...
  • Except that RALPP has it fully working for dCache - hope to get full report next week

  • Vcycle updated for Glance API 2.0 and to support Vacuum Pipe VM definitions.

Tuesday 14 Nov

Tickets

Monday 22nd January 2018, 15.00 GMT
54 Open UK Tickets this year.

Start with the good news - these tickets look like they can be closed:

BRISTOL
132880 (16/1)
It looks like transfers are working after the firewall fix. In progress (19/1) Solved, but CMS have hit Bristol with another xroot ticket: 132990

QMUL
132615 (26/12/17)
After changing the working directory LHCB jobs don't seem to be running out of space anymore, so the ticket can be closed. In progress (20/1)

TIER 1
132712 (4/1)
There seems to be positive news getting hyperK jobs working at the Tier 1, so maybe this ticket is sorted? In progress (22/1)

RALPP
132830 (12/1)
This complex CMS xroot ticket looks likely to be solved (in fact Chris might be closing the ticket as I type). In progress (19/1) Solved

Now onto the bad:

RHUL
132715 (4/1)
This ticket from Daniela about supporting the hyperK VO seems to have gone un-noticed. Can you please notice it? Assigned (4/1)

RALPP
132851 (15/1)
This CMS xroot ticket might be related to the one above, hence why it's not been tended to (indeed it might be able to be closed too). There's a request for some verbose output of an xrdcp from different CMS peeps, so the conversation is out of the site's hands for now. In progress (17/1)

QMUL
132713 (4/1)
Fixing hyperk jobs at QM on a couple of CEs. Dan had a kick of things a while back, how did that work out? In progress (4/1)

BIRMINGHAM
132569 (19/12)
Daniela spotted Dirac problems at Birmingham. Ultimately this is fallout from the Birmingham move to VAC, Daniela has suggested that Mark remove the VOs from the BDII to stop dirac sending jobs to an almost dead CE. Assigned (should be something else) (22/1)

MANCHESTER
132121 (28/11/17)
Any news or progress with this ticket to the VOMS service? There's been no updates with words in them from any site admins. In progress (1/12/17)

TIER 1
132589 (21/12/17)
LHCB pilots are still failing at the Tier 1 at Raja's last post, this ticket could do with an update from the Tier 1's side. In progress (10/1)

And the Ugly are a few tickets that need updates from the VOs:

MANCHESTER
132468 (14/12/17)
Alessandra updated this atlas transfer ticket with news that she has informed atlas of many lost files that were causing the errors. No news from anyone since. Perhaps someone from cloud support could update things? In progress (4/1)

IMPERIAL
132688 (3/1)
Daniela tried to poke Pheno over some lost files, but has had nothing but silence from them. Must have not been important files. Assigned (19/1)

132692 (3/1)
This LHCB ticket is in the same state as the Pheno one- waiting for someone from the VO to acknowledge the lost files. Assigned (3/1)

132683 (3/1)
The atlas equivalent of the previous two, Brian jumped on it when poked through another channel - so maybe these lines of communication aren't getting to where they should? In progress (22/1)

Tools - MyEGI Nagios
