  • There was an ops coordination meeting last Thursday 5th October: Agenda | Minutes.
    • There is one action for us to follow-up: "Collect plans from sites to move to EL7". We could make use of the Batch Systems table.


Tier-1 - Status Page

Tuesday 14th October A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here

  • There was a problem with CMS Castor service on Tuesday 7th Nov. after one of the "headnodes" failed and had to be replaced. CMS Castor was unavilable for around ten hours.
  • Castor will be unavailable for a few hours on Tuesday 14th Nov for patching of the nodes.
  • The LHCb Castor SRMs will be unavailable for a while on Wednesday 15th Nov. The Castor SRM version will be updated.
  • The "Test" FTS service (used by Atlas) has been enabled for IPv6 (i.e. dual stack enabled). The Production FTS will also have teh dual stack enabled next week.
Storage & Data Management - Agendas/Minutes

Wed 01 Nov

  • (very) modest progress on xcache testing...
  • Except that RALPP has it fully working for dCache - hope to get full report next week

Tuesday 3rd October

  • Looking for small DPM ATLAS site to possibly test xrootd caching
  • Tracking upgrade of SEs to new what will be new baseline versions. (dCache sites updated; 6/14 DPM up-to-date)
  • Alastair D. to give T2 site storage evolution talk 4/10/17 at gridpp-storage meeting

Wednesday 06 Sep

Wednesday 30 Aug

  • How will experiments use object stores in the future? Could the Sept. pre-GDB clarify this?
  • Fair bit of stuff known about advantages and disadvantages of erasure coding data, compressing data, etc. prior to storing it.
  • Bristol's curious missing SE - dropped out of the information system?
Tier-2 Evolution - GridPP JIRA

Tuesday 14 Nov

  • Single processor LHCb stoppable Monte Carlo VMs running in a mixture with fixed length 8 processor ATLAS VMs and single processor GridPP VMs.

Tuesday 3 Oct

  • Productions tests of Vac 03.00pre at Manchester.


Accounting - UK Grid Metrics HEPSPEC06 Atlas Dashboard HS06

Tuesday 24th Oct


Monday 16th January

  • The discussion topic for next week will be accounting comparisons. Please note Alessandra's comments last week.

Monday 14th November

  • Alessandra has written an FAQ to extract numbers from ATLAS and APEL avoiding the SSB.

Monday 26th September

  • A problem with the APEL Pub and Sync tests developed last Tuesday and was resolved on Wednesday. This had a temporary impact on the accounting portal.
Documentation - KeyDocs

Tuesday 14th Nov 2017

A significant change to VOMS records has been detected, and this may result in the release of a new Approved VOs document (to be announced). The change results from the apparent sudden retirement of all CNAF voms servers, which may or may not be "real". I'll check (sjones). The change concerns three VOs: ipv6.hepix.org, planck and enmr.eu. Sites supporting those VOs should check TB_SUPPORT over coming days to see if the changes are real.

Tuesday 26th Sept 2017

  • Safari on macOS autogenerated client certificates fix put into production last week.

Tuesday 19th Sept 2017

  • Bug in Safari on macOS causes random Apple generated client cert to be presented to www.gridpp.ac.uk using a CA we don't know about. The connection is then rejected by Apache. Other browsers ok since we request but do not require that they supply a certificate. Workaround produced by (a) installing the Apple CA root and intermediary CA and (b) whitelisting UK e-Science DNs (+ CERN? Others?) in the HTTPS Wiki plugin. Tested but not yet in production.

Tuesday 5th Sept 2017

New Approved VO. SKA European regional data centre, skatelescope.eu

https://www.gridpp.ac.uk/wiki/GridPP_approved_VOs

This VO is ramping up and has requested support. Andrew McNab is the contact person for GridPP.

Tuesday 4th July

  • There were a number of useful links provided in the monitoring talks at the WLCG workshop in Manchester - especially those in the Wednesday sessions.

Tickets

Monday 13th November 2017, 16.00 GMT
37 Open UK Tickets this week, but 13 of them are Ipv6 tickets.

IPv6 Tickets
Of these tickets 3 of them are still not acknowledged yet - Manchester, ECDF and Sussex. I set the UCL ticket in progress.

Liverpool
131677 (7/11)
This Ops ticket against one of the Liverpool CEs seems to have slipped under the radar. Assigned (7/11)

Tier 1
130207 (24/8)
This MICE storage ticket could do with an update from the Tier 1's perspective, even if it's "still waiting on some free disks to show up". On Hold (25/10)

124876 (7/11/16)
I cheekily tacked an update onto this ECHO Ops test failure ticket, to note how the linked issue had been poked by Alastair. On hold (13/11)

Oxford
129931 (4/8)
This Oxford http ticket could do with any update, even if it's a vacuous "haven't got round to upgrading yet" one. On hold (19/9)

Tools - MyEGI Nagios

Tuesday 18th July

  • Following our ops discussion last week, Steve will focus his tests on supporting the GridPP DIRAC area and decommission the other tests.
