| |
− | John Gordon ticketed the NGI (as well as others) about some sites in the UK not publishing core counts with their APEL numbers (or more precisely have submission hosts at that site not publishing). Following the link it looks like Imperial, Liverpool, Durham, Glasgow and Oxford are on this list, I've listed the submission hosts reporting "0" core jobs below to help people clear up their rogues! If you've only fixed things in the last fortnight you'd still show up on this list. In progress (15/6)

− | Sno+ file copying ticket. Matt M is away on his hols, but Dave Auty has took over his duties and reports that this problem seems to have gone away - it can probably be closed. In progress (9/6)

| |
− | Another Sno+ ticket here from David concerning job failures. Nothing wrong with the ticket handling, but I thought that David's errors in submitting test jobs are worth documenting, as they were very understandable. David has since asked if the Sno+ job failures are linked to Sno+ nagios test failures at Liverpool. In progress (12/6)

− | Oxford being ticketed for UKI-SOUTHGRID-OX-HEP_IPV6TEST failing connection tests, tests for which Oxford should not be getting ticketed afaacs. I remember this being mentioned in the Thursday cloud meeting, but I'm ashamed to say I wasn't paying attention. Were any conclusions drawn/decisions made? In progress (10/6)

General updates
|
- BDII discussion.
- he IGTF is about to release an update to the trust anchor repository (1.65)
- hone has completed its use of the grid.
- CVMFS space for GridPP VO: /cvmfs/gridpp.gridpp.ac.uk or /cvmfs/gridpp.egi.eu

- JANET is working with Imperial College to establish a VRF to perform tests of a connection to LHCONE.
- Please could everyone who supports gridpp ensure that the site accepts jobs with the pilot role? In addition please also consider the other VOs mentioned in Daniela's email (17:30 on 15th June).
- Glasgow: VO Shares and ARC CE config question.
- WLCG workshop 2016: last call for volunteers.
Tuesday 9th June
- ARC issue: Arc wrapper is changing the permissions of certain job files. Actually it changes the permissions of file with suffix ".comment" and only for jobs that are coming from certain WMSes.
- A/R for May:
- ALICE:
- ATLAS:
- UCL: 37%:77%
- Birmingham: 75%:75%.

Tuesday 25th May
- VO updates:
- LIGO issue looked like DNS resolution issue. Sam following up this week. Noted DIRAC errors truncated. Suggested trying non-IC disk. Tom reported: CERN@school-enabled disks - QMUL-disk, GLASGOW-disk and LIVERPOOL-disk worked on every network tried with various instances of the GridPP CernVM with the DIRAC UI installed... so issue elsewhere.
- LZ: Andy W: Met Paolo (Edinburgh) from LZ to walk through the basics (in parallel with LZ computing on the Grid being established). AW joined the GridPP VO to assist.
- gridpp-support at jiscmail ac uk created.
- Friday WMS issue?: svr024.gla.scotgrid.ac.uk has been removed from the Nagios configuration. Most CEs quickly returned from 'unknown' state, and others came back to normal in the next round of tests.
- Tier-1problems with secondary database system for Castor - resolved quickly.

Tier-1 - Status Page
|
- A reminder that there is a weekly Tier-1 experiment liaison meeting.
- The agenda follows this format:
- 1. Summary of Operational Status and Issues
- 2. Highlights/summary of the Tier1 Monday operations meeting (Grid Services; Fabric; CASTOR and Other)
- 3. Experiment plans and operational issues (CMS; ATLAS; LHCb; ALICE and Others)

Castor will be shutdown just before this and restarted afterwards. This is to enable a test of a change to our network configuration that was made a couple of weeks ago.

Storage & Data Management - Agendas/Minutes
|
Wednesday 17 June
- EU projects - SAGE: HSM for HPC
- Progress on new VOs. Can test as members of 'gridpp' or similar until they get their own allocations.
- We've talked about it before; should VOs have individual T2 allocations to avoid stepping on each other's toes?
- Case for expanding back-up-into-T1 to other VOs?
Wednesday 27 May
- Working on troubleshooting DIRAC data for/with LIGO (not to be confused with DiRAC or with any of the other things called DiRAC)
- Working on setting up DiRAC at Tier 1 (not to be confused with DIRAC or Dirac or with any other thing called Dirac)
- New secret user support list!
Tuesday 18th May
Tuesday 21st April
- Has there been any Tier-1 contact with DiRAC?
- Proposal to setup an 'other VOs' users list. GridPP-Users is too tied with WLCG projects.
Wednesday 15 April
- Backing up data from DiRAC to GridPP (tape)
- More case studies on supporting non-LHC VOs on GridPP: we have a lot of great stuff that can do great stuff - non-LHC VOs tend to have less regimented data models so maybe we need more case studies.

Documentation - KeyDocs
|
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 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.
Tuesday 21st April
- There was an EGI ops meeting on Monday 20th.
- David updated the UK SL5 response.
- Please review the agenda/minutes.

On-duty - Dashboard ROD rota
|
Monday 8th June
- The eu.repository has now made a comeback, so the arc alarms, cleared, but I the site availabilities (probably) need to be corrected.
- Still getting on/off bdii alarms for a variety of sites.
Monday 11th May
- Rota responses awaited from Andrew and Daniela.
- Handover summary should be uploaded to the bulletin please.

Rollout Status WLCG Baseline
|
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.

Tools - MyEGI Nagios
|
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/
