| General updates
|
Tuesday 21st July
- Various requests (e.g. via EGI) to express interest in "Compute Resources for PanCancer Analysis of Whole Genomes" call.
- MM raised a question about remote loading of Grid files for SNO+ (email 20th July).
- From Winnie: yaim on CREAM-CE - no update of var/lib/bdii/gip/ldif/ files. Should it?
- From Catalin (16th July): The decommissioning process of the 'gridpp.ac.uk' CVMFS space is about halfway, and it came to my attention the fact that sites are defining the CVMFS_REPOSITORIES variable at WN level. Whilst this variable was mandatory with cvmfs v2.0.X, this is not case with v2.1.Y. I would ask site admins to remove the 'gridpp.ac.uk' repository names from there, except the regional UK VO repositories (londongrid, scotgrid, southgrid, north grid)
- /cvmfs/gridpp-vo help. Down to the repository? Is more documentation needed here?
- Atlas ADC meeting containing discussion of the future of cloud support is at 4.30 on the 21st of July, and sites are welcome to attend.
- For those who missed it: [arxiv.org/abs/1507.03414 observation of a new particle with LHCb]! Also see the press release.
- Minutes of the last EGI operations meeting are now available.
- Process for uploading files to CVMFS.
Tuesday 14th July
- There was a GDB at CERN last Wednesday agenda: minutes.
- Very worthwhile reviewing Romain's talk from the GDB on threats.
- Raja noted: It looks like some certificates have problems when submitted to CEs with RHEL5 variant OS-es underneath. Does this need further investigation/work?
- Matt: reports that the EMI WN tarball now contains gfal CLI utilities.
Tuesday 7th July
- Reminder: on July 17 a 4 hour long EGI Federated Cloud tutorial will be organised in London (at SAP near Heathrow). It's a free event, part of a 3-day long software carpentry workshop.
- Q2 15 quarterly reports are now due!
- There is a UKNGI ticket on multicore accounting that still requires some sites to act.
- Proposal for a DPM workshop 16-17th of November or possibly 19-20th. Any comments?
- The draft T2 reliability and availability figures for June have been produced.
- ALICE: All okay.
- ATLAS: All okay.
- CMS: Bristol (89%:100%) - so just under the cut-off.
- LHCb: Sheffield: (64%:64%); RALPP: (83%:83%).
- EGI Community Forum 2015: Call for Participation open! Deadline: 12 July
- A summary of a recent ARGUS collaboration meeting is now available.
- There is a WLCG GDB this week.

| Documentation - KeyDocs
|
Tuesday 23rd June
- Reminder that documents need reviewing!
Tuesday 9th June
LSST voms2 records are not present in VOID cards yet.
As a workaround, a temporary note of the actual
values has been added to the LSST section of
Approved VOs.
https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs
General note
See the worst KeyDocs list for documents needing review now and the names of the responsible people.
Tuesday 21st April
- The Approved VOs document has been updated to take account of changes to the Ops Portal VOID cards.For SNOPLUS.SNOLAB.CA, the port numbers for voms02.gridpp.ac.uk and voms03.gridpp.ac.uk have both been updated from 15003 to 15503. Sites that support SNOPLUS.SNOLAB.CA should ensure that their configuration conforms to these settings: Approved VOs
- KeyDocs still need updating since agreements reached at last core ops meeting.
- New section in Wiki called "Project Management Pages".
The idea is to cluster all Self-Edited Site Tracking Tables
in here. Sites should keep entries in Current Activities
up to date. Once a Self-Edited Site Tracking Tables has
served its purpose, PM to move it to Historical Archive
or otherwise dispose of the table.

| Interoperation - EGI ops agendas
|
Monday 13th July
- There was an EGI Ops meeting today: agenda
- URT/UMD updates:

- gfal2 2.9.1
- storm 1.11.9
- srm-ifce 1.23.1....
- gfal2-python 1.8.1
- In Verification
- gfal2-plugin-xrootd 0.3.4
- Accounting
- [John Gordon] "Of the WLCG sites we now have 97%+ of cpu reported with cores. I expect you all saw my recent email to GDB naming 16 sites. If one German and one Spanish site and the four Russians start publishing we will jump to 99%+"
- New list of sites needing to update multicore accounting being prepared this evening (Monday) by Vincenzo
- SL5 decommissioning date March 2016;
- Next meeting 10th August
Monday 15th June
- There was an EGI operations meeting today: agenda.
- New Action: for the NGIs: please start tracking which sites are still using SL5 services: how many services, and for each service if still needed on SL5, if upgrades on SL5 services are expected). A wiki has been provided to record updates. Also interesting to understand who is using Debian.

| On-duty - Dashboard ROD rota
|
Monday 13th July
- Quiet week, once the (unofficial) ARC fix was implemented on the nagios side.
- Low/best efforts ROD effort after this week for 1-2 weeks.
Monday 6th July
- DB: Between the fake ARC alarms and the fake bdii alarms it's hard to see the real alarms.
Monday 22nd June
- Generally quiet. There are some 'glue2' errors that were ticketed. Tried to let these go and see if they would clear. However, in some cases the amount of time the error was outstanding was building up. Unclear if Glue2 is used anywhere.

Tuesday 12th May
- MW Readiness WG meeting Wed May 6th at 4pm. Attended by Raul, Matt, Sam and Jeremy.
Tuesday 17th March
- Daniela has updated the [ https://www.gridpp.ac.uk/wiki/Staged_rollout_emi3 EMI-3 testing table]. Please check it is correct for your site. We want a clear view of where we are contributing.
- There is a middleware readiness meeting this Wednesday. Would be good if a few site representatives joined.
- Machine job features solution testing. Fed back that we will only commence tests if more documentation made available. This stops the HTC solution until after CHEP. Is there interest in testing other batch systems? Raul mentioned SLURM. There is also SGE and Torque.

- 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 14th July
- GridPP35 in September will have a part focus on networking and IPv6. This will include a review of where sites are with their deployment. Please try to firm up dates for your IPv6 availability between now and September. Please update the GridPP IPv6 status table.
Tuesday 23rd June
- GridPP issued a position statement regarding LHCONE.
- ...Concerning LHCONE for both T1 and T2. The high level summary is that the UK is not in favour, as within the UK we have no explicit need for LHCONE for any reason of T1 capacity planning, but to implement it involves additional complexity and possibly cost. The current system works fine and we therefore see no overriding reason to remove T1-T1 transit via LHCOPN. ...The UK is sensitive to the “collective” needs of the community, and as a general statement we would always seek to address any legitimate request agreed by the WLCG MB in order to play our role in meeting international expectations.
Tuesday 12th May
- LHCOPN & LHCONE joint meeting at LBL June 1st & 2nd. Agenda taking shape.

| Tickets
|
Monday 27th July 2015, 16.10 BST
Only 20 UK Tickets this week, and many are on hold for summer holidays. I pruned a few tickets, but none are striking me as needing urgent action, so this will be brief.
Mandatory UK GGUS Link
Nothing to see here really, but maybe I'm missing something? Nit-picking I see:
114381 (publishing problems at Durham) could still do with an update - not sure if work is progressing offline on the issue.
The Snoplus ticket 115165 looks like it might be of interest for others - in it Matt M asks about tape-functionality in gfal2 tools. Brian has updated the ticket clueing us in about gfal-xattr.
UK T'other VO Nagios
A few failures here at time of writing - although only one at Brunel seems to be more then a few hours old (dc2-grid-66.brunel.ac.uk is failing pheno CE tests).
Let me know if I missed ought!

Tuesday 09 June 2015
- ARC CEs were failing nagios test becuase of non-availability of egi repository. Nagios test compare CA version from EGI repo. It started on 5th June and one of the IP addresses behind webserver was not responding. Problem went away in approximately 3 hours. The same problem started again on 6th June. Finally it was fixed on 8th June. No reason was given in any of the ticket opened regarding this outage.
Tuesday 17th February
- Another period where message brokers were temporarily unavailable seen yesterday. Any news on the last follow-up?
Tuesday 27th January
- Unscheduled outage of the EGI message broker (GRNET) caused a short-lived disruption to GridPP site monitoring (jobs failed) last Thursday 22nd January. Suspect BDII caching meant no immediate failover to stomp://mq.cro-ngi.hr:6163/ from stomp://mq.afroditi.hellasgrid.gr:6163/
