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.

Monday 22nd May

• Issue with dirac-dms-get-file affecting vo.moedal.org.
• HTCondor workshop in Europe 2017 6th-9th June. More information.
• ARGO Monitoring Downtime - Tuesday, 23 May, at 7:00 AM CEST, there will be scheduled down time for approximately 6 hours.
• 2017 WLCG Workshop: registration extended
• Downtime declarations discussion (3days or 5 days notice....!)
• CHEP papers - final weeks for revisions.
• Fourth release of the Accounting Portal ready for testing. Feedback via GGUS 127920.
• Final T2 availability & reliability - April 2017.
• CA reminders... some observations
  • Reminders are working as well as they always have
  • Special case if you have multiple certs which expire soon after the other [which isn't actually permitted and hence not expected] the reminders come late
  • Please don't send CA tickets to TB-SUPPORT as it is a publicly visible mailing list and if things turn into non-issues then can be seen as bad advertising for no reason
  • Don't rely on the CA to remind you – setup your own reminders
  • "fixing" this issue (multiple certs) is plausible, but as it is deep within code (there are several levels of code involved here in more than 1 language) then it might be error-prone and hard to test.
• EGI Operations Broadcast - May 2017
  • Failures with CREAM-CE JobCancel probe
  • Decommissioning of dCache 2.10
• Notes from the May GDB are now available.

Tuesday 16th May

Monday 22nd May

• WLCG ops coordination took place last Thursday with a theme of "providing reliable storage" : Agenda | Minutes.

Tuesday 6th June A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here

• All Castor instances have now been upgraded to version 2.1.16. This includes upgrading the SRMs to version 2.1.16 as well. As part of this the SRMs were upgraded to SL6 thereby removing the final SL5 systems that were providing an external facing service.
• Atlas have successfully carried out a deletion test of data in Echo.
• LIGO and the MICE pilot role have now been enabled for batch access.
• The Edinburgh Dirac site is transferring data in production. Currently around 2 to 4TB per day. There is a total of around 400TB to transfer in this tranche.
• The new version of FTS3 installed on our "test" FTS service (used by Atlas) no longer supports the SOAP API. There are still some access to our "production" FTS3 service via this API (mainly SNO+ and MICE). We will wish to upgrade the production FTS3 service - and need VOs to move to the rest API provided with the newer versions of FTS. Would like to set deadline when we upgrade the "production" instance and hence no longer support the SOAP API.

- 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 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

Monday 6th March

• Last week it was noted that some ATLAS RIPE probes (the USB ones) have had hardware errors. If you need a replacement and RIPE are slow to respond then contact Jeremy.
• Is anyone running any tests with their RIPE probe?

Tuesday 14th February

• The development dashboard is now operational again. However the production dashboard is not currently displaying latency results (OSG ticket submitted).
• Birmingham pS host had lost its entire network connection and both Lancaster's hosts their IPv6 connection. Durham results are incomplete, GGUS ticket submitted (#126587).

Tuesday 25th October

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

Monday 5th June 2017, 14.30 BST
Down to 21 Open UK Tickets this month.

SUSSEX
122772 (11/7/116)
Atlas xroot/webdav ticket, with just xroot to go. Any luck with the xrootd server? In progress (9/5)

127767 (18/4)
Availability ticket - Daniela notes that there are still issues with test jobs not running in time, and advises perhaps reserving a slot for tests. On hold (25/5)

RALPP
127555 (7/4)
Another availability ticket, although Chris points out several valid reasons why this points to the monitoring being fubared, vitiating RALPP's results. On hold (30/5)

OXFORD
128512 (27/5)
LHCB spotted a problem with the Oxford ARC CE, which Kashif seems to have cleared up with a reboot, but no word from lhcb since. Could do with a poke. In progress (30/5)

BRISTOL
126864 (28/2)
Request to enable LZ at Bristol. Winnie is progressing with rolling out the pool accounts etc for LZ, Dune and LSST as fast as her limited time allows. In progress (30/5)

GLASGOW
124052 (25/9/16)
The cursed ticket, requiring new ARC CEs to fix a problem with publishing seen by lhcb. Hopefully enough positive karma has been accrued to give some breathing space to get round to this. On Hold (4/4)

ECDF
128294 (12/5)
Availability ticket - looking into the ECDF argo page is a journey into the unknown (status), with their infamous -1 availability. If you're site seems to be capping out at 99% then I'd blame the ECDF guys for stealing that extra 1% :-P In progress (19/5)

SHEFFIELD
127766 (18/4)
Another availability ticket, just waiting for the numbers to sooth themselves. Hopefully not too badly affected by the next ticket. On hold (25/5)

128429 (19/5)
BDII test failure ticket, the alarm was fixed by Elena syncing her clocks, but glue-validator failures are still seen. Kashif right recommends running the test manually. In progress (2/6)

LANCASTER
128321 (15/5)
And another Availability ticke. After improving test job flow through our cluster we're on holding the ticket. At least we're in good company. On hold (26/5)

RHUL
128750 (1/6) Duncan submitted a perfsonar related ticket after spotting some problems, Govind is investigating the issue. In progress (5/6)

IMPERIAL
128555 (30/5)
The Imperials are having an issue with gfal-copy within CMS jobs. Despite not being able to replicate manually, some quiddity of the job environment causes gfal-copy to seg fault. The site has tried a different version and raising the ulimit, but no joy yet despite the efforts. In progress (5/6)

100IT has 3 tickets that I won't go into.

TIER 1
124876 (7/11/16)
gridftp tests failing for echo, due to a problem with the tests. No movement on the counter ticket (125026) since April. On Hold (1/1)

127612 (8/4)
LHCB having problems with the RAL CEs, which seem to be ongoing (although they might have changed in nature). No news on the ticket in the last fortnight though. In progress (23/5)

127967 (27/5)
Enabling MICE pilots at the Tier 1. The accounts are created but it looks like job submission isn't working yet for this role. In progress (25/5)

127240 (21/3)
CMS staging tests. The last entry from the user was a request to clarify what the numbers in the plots meant and for additional plots. In progress (18/5)

127597 (7/4)
CMS would like the Tier 1 to check their xroot/networking performance. In response Andrew L had switched off "lazy download" Andrew asked if this has helped, but the issue is muddled by the firewall at RAL dropping packets, awaiting news from the RAL networking team. In progress (30/5)

117683 (18/11/2015)
Castor Glue 2 publishing ticket. Rob updated that development is still ongoing. On Hold (10/5)

29th November 2016
