- This includes notifying of (inter)national services that will have an outage in the coming weeks or will be impacted by work elsewhere. (Cross-check the Tier-1 update).

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!


Tickets

Monday 7th August 2017, 15.00 BST
24 Open UK Tickets this month.

NGI
129964 (7/8)
We got ticketed about our tickets! Or to be more exact, we had too many "very urgent" tickets last month that weren't responded to within 1 working day. Of the three such tickets, the QMUL one was well understood, whilst I suspect the Oxford and RALPP tickets were simply missed (and I'm not sure how very urgent they were). So please please set your tickets in progress as soon as you start them, otherwise I have to deal with tickets about tickets, and that's a bit too meta for me! In progress (7/8)

STORAGE ACCOUNTING TICKETS
Cambridge, Bristol, Edinburgh, Liverpool, Lancaster and IC - all are On Hold awaiting "Phase 2" of this campaign.

SUSSEX
122772 (11/7/16)
Atlas webdav/xroot ticket. Any joy with the xroot? In progress (10/7)

RALPP
129886 (1/8)
A request from CMS to check the HC xroot rates the site. Chris couldn't see a problem, so has asked for clarification (and some clues). Waiting for reply (2/8)

129913 (3/8)
CMS transfers failing to the site due to lack of space. Ian has created a dump to help CMS clean up their files - he just needs to know where to put it! Any help from anyone who has done this for CMS before would be appreciated. Waiting for reply (7/8)

OXFORD
129931 (4/8)
As seen by Pete's thread on the storage list, atlas http SAM tests are failing at Oxford. Pete is fighting the good fight. In progress (7/8)

BIRMINGHAM
129930 (4/8)
The same ticket for Birmingham. Perhaps Oxford can trailblaze with this issue? (if it's the same problem.) Assigned (4/8)

SHEFFIELD
129520 (12/7)
A standard issue availability ticket. On hold (12/7)

LIVERPOOL
129296 (30/6)
LHCB ticket about the low number of jobs running at the site, explained to be due to the lower number of cores online whilst the machine room is refurbished. The ticket could do with an update though to let us know how things are coming along. In progress (30/6)

QMUL
129692 (24/7)
LHCB transfers failing during QM SE woes at the end of July. It looks like things are much better now, so I suspect that this ticket can be closed. In progress (2/8)

129155 (26/6)
XROOT not working for lhcb at QM - last update, shortly before Dan's holiday (and the SE keeling over) a test infrastructure was put into place to get round no one at the site having lhcb credentials. Any luck with this, or has things been too busy? In progress (25/7)

IMPERIAL
129946 (6/8)
LHCB having trouble uploading to SARA. I'm wondering if this is a problem SARA end... Waiting for reply (7/8)

BRUNEL
129807 (27/7)
A long and involved CMS ticket about squids. I didn't follow it all, but one port Raul brought up was that I don't think there's a document detailing the ports that sites need open. The ticket has moved to talk about squid monitoring on the side. In progress (4/8)

100IT
Have one ticket (129023) that's being handled well.

TIER 1

127597 (7/4)
A CMS ticket to check the RAL networking/xroot performance (similar to the previous one), waiting on news from the RAL networking team for the last 3 months as they investigate a firewall problem. On hold (14/6)

128991 (16/6)
Tape support for solidexperiment.org. Waiting on the Tier 1 Resources Meeting at last check. On Hold (20/7)

124876 (7/11/16)
