Week commencing Monday 30th October 2017
Task Areas
General updates

Monday 30th October


Monday 23rd October

  • WLCG ops update from Monday 23rd.
  • Some TB-SUPPORT queries in the last 10 days:
    • Alessandra asked about: arc, htcondor, cgroups limit setup. A user was using x13 more memory!
    • Govind asked: How do you monitor your network switches i.e Force10/dell switches?
    • Simon asked: is anyone buying or recently bought new network switches for their Tier2?
    • Chris: ELK stack, do you put all the different sources of data into the same indexes in elastic search or do you have separate sets of indexes for different data sources.
  • 10th October: If you are willing to add support for NA62 on your Tier-2 site please have a look at the details in the wiki.

Tuesday 10th October

  • There is a GDB this Wednesday. Agenda
  • EGI Trust Anchor 1.86-1 has just been released.
  • The T2 figures for September have been circulated.
    • ALICE
      • Oxford: N/A: N/A
    • ATLAS
      • Liverpool: 79%:89%
      • Sheffield: 88%:88%
    • CMS
      • All okay
    • LHCb
      • Liverpool: 80%: 100%
    • Issues encountered:
      • Sheffield: One WN had a CVMFS access problem.
      • Oxford: BDII is dual stack. New switch/router changed IPv6 setup. CERN’s BDII could not see site. Site lost from REBUS.
  • Simon asked about: ATLAS WN specs.
  • GridPP40 - Pitlochry April 10,11th 2018


WLCG Operations Coordination - AgendasWiki Page

Monday 23rd October

  • The next WLCG ops coordination meeting will be on 2nd November.

Tuesday 10th October

  • 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.

Tuesday 3rd October

  • The next WLCG ops coordination meeting will be on 5th October - agenda.

Tuesday 19th September

  • The agenda and minutes from the WLCG ops meeting on 14th September are now available.
  • The next meeting is planned for 5th October.
Tier-1 - Status Page

Tuesday 24th October A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here

  • There was a problem with Atlas file transfers to Echo that started around the 11/12th Oct. This was traced to the update to the "test" FTS3 service (used by Atlas). During this upgrade some FTS settings were changed. The relevant parameter here being the number of concurrent streams for a transfer. The FTS3 settings were re-instated earlier this week and the problem solved.
Storage & Data Management - Agendas/Minutes

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 3 Oct

  • Productions tests of Vac 03.00pre at Manchester.

Tuesday 19 Sep

  • Running LHCb production MC in Docker and Singularity containers on Vac. Since GridPP39, CPU and memory cgroups wrapper around Singularity Containers has been added.

Tuesday 5 Sep

  • Docker and Singularity container support in Vac 03.00pre

Tuesday 29 Aug

  • Prerelease of Vac-in-a-Box (i.e. GitHub master) is now running on CentOS 7, for Vac 02.01.
  • Aiming for combined Vac/Vac-in-a-Box release with CentOS 7, but with continued SL6 support for Vac.


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 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.
