Monday 3rd July

• July 2017 GDB and pre-GDB. Draft agenda available. Container technologies working group pre-GDB contact Gavin McCance to get involved.
• Winnie: Do sites need lcg-CA installed?
• EGI: Usage of ops VO. Is anyone still using it for UK tests?
• June T2 reports:
  • ALICE
    • All okay.
  • ATLAS
    • Lancaster: 84%:85%
  • CMS
    • All okay
  • LHCb
    • Lancaster: 83%:84%
    • Oxford: 70%:100%
• The agenda of the WLCG ops meeting held on Monday is available.

Monday 26th June

• GOCDB has received a new service type request for: ‘eu.egi.storage.accounting’: - authorising the site/SE to publish the storage accounting data - making the site/SE appear in the portal - monitoring that the accounting data are regularly published.
• The registration to the next LHCOPN/LHCONE meeting is now open. LHCONE meeting agenda: https://indico.cern.ch/event/646629/.
• HEPiX Fall 2017 meeting will be held at KEK, Tsukuba, Japan, from 16th to 20th October. HEPiX registration page: http://hepix-fall-2017.kek.jp/registration.html.
• Chris B: Gotcha when upgrading ArcCEs to htcondor 8.6
• EGI: new nagios probes appdbsync and OCCI-Categories for testing cloud services
• Dan: cvmfs versions. It seems others are running 2.3 and 2.4 versions.
• 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.

Monday 5th June

• Migration of the UI/WN tarball repositories.
• EGI RP/RC A/R Report available. UK is fine but dropped in April.
• Tier-1 noted pool accounts for "quiet" VOs. The question, is it worth spending time getting the VO active:
  • camont - no. This collaboration ended some years ago.
  • cdf - no
  • dzero - no
  • esr - no, but they might.
  • magic - no, but they might
  • neiss - no
  • supernemo - They will be soon. Discussions started.
• Winnie: Pool account UIDs/GIDs. Looks like it is best to work towards having consistent pool accounts.
• lusc-gridpp mailing list for LSST now created. A while back Alessandra also set up a wiki page for LSST.
• Alastair: Site feedback for network session at WLCG workshop.
• The EMI repositories will be shut down on the 15th of June 2017. You should be on the preview repo now. h Third party repo is here.
• 29th May: EGI Trust Anchor release 1.83-1.
• Two WLCG ops meeting reports to review: 29th May and 5th June.

• Lots of good presentations and discussions at both hepsysman and the WLCG workshop. Even if we didn't finish all the things...

Wednesday 17 May

• Lots of opportunities to contribute to WLCG workshop (if we could finish all the stuff we've got cooking)

Wednesday 19 Apr

Tuesday 4th July

• Pete C is preparing another networking forward look document. Note that figures presented in the Manchester workshop were for a Tier-2 (not always a single site).

Tuesday 6th June

• 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.

Tuesday 25th April

• perfSONAR version 4 was released on 17th April. Sites with auto-update on should have been automatically upgraded. Note perfSONAR 4.0 requires more CPU than previous versions as a result of some of the increased functionality. Full details here

• Duncan has recreated the UK perfSONAR mesh. Link here!

36 Open UK Tickets this month.

SUSSEX
122772 (11/7/16)
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)

127767 (18/4)
An availability ticket, hopefully the stats will be green enough to close this in a week or two. On hold (26/6)

RALPP
129312 (3/7)
Fresh this morning, an lhcb ticket about one of the ARC CEs not responding (heplnv147). Assigned (3/7)

129316 (3/7)
A ROD ticket about the same server. My powers of deduction suggest that it's a bit poorly. Assigned (3/7)

OXFORD
129201 (27/6)
A glue2 ROD ticket. Kashif sees an intermittent failure and had no joy debugging it so will close the ticket shortly. In progress (29/6)

CAMBRIDGE
129187 (26/6)
One of the "check your storage accounting" tickets, just waiting on word back from JG to try out a new gocdb related to this. Waiting for reply (28/6)

BRISTOL
126864 (28/2)
Enabling LZ (and friends) and Bristol. Things are coming along nicely, and after giving helpful advice about glexec Daniela is primed to send test jobs. In progress (15/6) Update, Winnie has got back reporting that LZ, Dune and LSST are ready for testing. Sweet!

GLASGOW
124052 (25/9/16)
LHCB ticket regarding publishing ARC at Glasgow (aka the Cursed Ticket). Gareth has updated the ticket with two prongs of hope - one is that a CE at Glasgow has been updated to a version of ARC with the hopeful fix in it, and the other is that VAC use by LHCB at Glasgow could make the issue moot. Both need feedback to confirm. Waiting for reply (30/6)

EDINBURGH
129185 (25/6)
The ECDF edition of the storage accounting tickets. Waiting on Andy's return from hols to confirm the figures. In progress (26/6)

SHEFFIELD
129230 (28/6)
Atlas transfers failing with time outs - Elena noted a rogue disk server and hopefully has kicked it into shape soon. In progress (3/7)

129054 (19/6)
Atlas mcore jobs being killed a Sheffield. At first glance Elena suspected the jobs hit the time limit, but CREAM errors have been spotted. Let us know if you need a hand debugging this. In progress (21/6)

LIVERPOOL
129296 (30/6)
LHCB wondering why they're not seeing more jobs at Liverpool. John politely reported on the state of the Liverpool AC. Hope things stay cool(ish). In progress (30/6)

129184 (26/6)
The Liverpool storage accounting check ticket - John provided some good feedback. In progress (30/6)

129288 (30/6)
Duncan spotted a problem with the Liverpool perfsonar results. John reports a full root partition and has resized it. Hopefully nothing go fubared, playing the wait and see game. In progress (30/6)

LANCASTER
129183 (25/6)
The Red Rose edition of the Storage Accounting Check. I was hoping to close this today, but my dpns-du is still going. In progress (27/6)

129242 (29/6)
Availability ticket after a rocky few weeks, on the road to recovery now. On hold (3/7)

129287 (30/6)
Another ticket from Duncan, the Lancaster perfsonars hadn't initialised their IPv6 address properly after a reboot. Fixed, but needs investigating. In progress (30/6)

RHUL
129223 (28/6)
In its continued decommissioning, Daniela has asked that vo.londongrid.ac.uk be removed from the site. Govind just has the SE to go. In progress (28/6)

QMUL
129221 (28/6)
A similar vo.londongrid.ac.uk decommissioning ticket for QM. Not spotted yet? Assigned (28/6)

129155 (26/6)
LHCB having issues accessing files over xroot at QM. This has only been tried in anger for atlas before, so it looks like some teething troubles are being seen. Daniela has asked for a handy CMS file to try out just in case. In progress (3/7)

IMPERIAL
129182 (25/6)
The Imperial storage accounting ticket, Simon replied and just waiting on the gocdb thing now. Waiting for reply (28/6)

128555 (30/6)

BRUNEL
129222 (28/6)
Just an londongrid vo decommissioning ticket here, progressing nicely. In progress (1/7)

100IT
Have 4 tickets, only one properly fielded:

129023
128095
129156

THE TIER 1
129299 (3/7)
A CMS user spotted errors trying to pull data from RAL. Looks like checksum differences - the user has got back and it looks like the file is corrupt. In progress (3/7)

129211 (27/6)
Atlas transfer failures to Tokyo - they seem to be gone now, despite nothing being fixed or found to be wrong. If still fixed the ticket can be closed. In progress (29/6)

129059 (20/6)
LHCB spotted timeouts, which look to have since been resolved. Just waiting on confirmation of this before closing the ticket. Waiting for reply (28/6)

129098 (22/6)
Another atlas transfer ticket, thanks to Alastair and Gareth for trying to clear things up between the two issues. Are these globus errors still occuring?. In progress (29/6)

129228 (28/6)
A CMS ticket for low xroot success rates for HC jobs. A restart of xrootd redirectors seems to have fixed a few issues for Andrew at least, waiting on user feedback. Waiting for reply (30/6)

127597 (7/4)
A CMS ticket checking on site networking at RAL, waiting on a update from the RAL networking team. On hold (14/6)

128991 (16/6)
solidexperiment.org requesting tape support at RAL. Passed on to the castor team. In progress (16/6)

124876 (7/11/2016)
