Week commencing Monday 28th November 2016
Task Areas
General updates

Monday 21st November

  • There is a GridPP Oversight Committee meeting this week.
  • ATLAS - APEL accounting records comparison. Bug found in scripts for ARC and Torque.
  • Marcus: xrdcp test for sites with DPM.
  • The EGI Security Policy Group has produced a new revised and updated Top-Level Security Policy document. This brings the document up to date in terms of terminology and the current set of security policy documents, although one of our aims was also not to change more than we needed to (as the old document has served us well over many years!). Just to be clear – this policy applies to ALL current and future EGI infrastructures and services. The draft is available for comment until the OMB this Thursday.
  • HEPSYSMAN 2017 dates to be confirmed soon.
  • A new release of the Accounting Portal is ready for testing. Please test the new release for the next 2 weeks, and report via the tracking GGUS ticket any comment, bugs or suggestions for improvement.
  • WLCG meeting (pre-GDB) on networking: 10 Jan 2017 at CERN. It will be the opportunity for LHC experiments, Network operators, WLCG service and site managers to meet and discuss the network requirements for the 3rd run of the LHC, planned for 2021-2023.
  • The ARC brainstorming camp takes place 28th November - 2nd December.
  • Reminder of Andy W's request on: Call for UK feedback to the ARC brainstorming camp.

Tier-1 - Status Page

Tuesday 29th November A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here

  • Owing to staff availability the upgrade of Castor to version 2.1.15 is being scheduled to take place in January.
  • A problem on the Castor 'GEN' instance started on Monday (21st Nov) following the renewal of the host certificates on the SRMs. These were lacking the additional alias names. Tickets (from Mice & SNO+) not picked up until Wednesday morning when the problem was resolved.
  • Additional disk servers have been added to Castor: For Alice 5 extra servers, each 100TB. For LHCb 12 additional servers, each 120TB. This will enable both an increase in capacity and the withdrawal of some older (smaller capacity) disk servers.

Tier-2 Evolution - GridPP JIRA

Tuesday 22 November

  • Next generation LHCb pilots / VMs deployed at all VM-based sites. Includes multiple parallel payloads support for multiprocessor VMs and new WLCG SAM probes framework, addressing JIRA task GridPP-5
  • Vac 2.0 mixed-sized VMs support in testing, using Super Slots mechanism to create multiple single-processor VMs in groups to avoid breaking up N processor slots for multiprocessor VMs.
  • skatelescope.eu and LHCb demo at RCUK workshop on 29th Nov, showing transparent access to OpenStack resources at DataCentred Ltd and CERN using GridPP/LHCb DIRAC services and DIRAC VMs.

Tuesday 15 November

  • LHCb prototype of implementation of SAM probes for VMs done. Next step is to install the client script in the ETF/SAM test setup and test at multiple sites. Once finished, will address JIRA task GridPP-5

Tuesday 8 November

  • Agreement with ETF about how to implement SAM probes for VMs, initially for LHCb. (We will use an external service provided by LHCb which the probes inside the VMs will report to.)
  • Enabling DataCentred and StackHPC to run skatelescope.eu jobs in GridPP DIRAC VMs. i.e. two OpenStack providers with academic links.
  • Vcycle at 1.0 prerelease, and now includes an Admin Guide.

Documentation - KeyDocs

Tue 22nd Nov

  • More on Accounting audit tools

The process for ARC, Toque and VAC is now documented here.


Tue 15 Nov

  • Accounting audit tools

GridPP project in github used to host documents and scripts to audit work done accounts independently of APEL. So far, methods exist for ARC CE, and Torque batch system. Method for VAC still rough and being worked out by (e.g.) next week. To get the material:

git clone https://sjones-hep-ph-liv-ac-uk@github.com/gridpp/audit.git

Substituting you own github username. Or go to:


For write access, ask Andrew McNab.

  • Changes to CMS resource requirements in Approved VOs

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

Scroll to the Resources table at the bottom and check the new CMS requirements.

Tue 1 Nov

Publishing tutorial updated to use new wording for various measurements.

Tools - MyEGI Nagios

29th November 2016

LSST monitoring is available through vo-nagios


13th September 2016

19th July

Both instances of gridppnagios at Oxford and Lancaster has been decommissioned.

12th July 2016

Central ARGO monitoring service has started from 1st of July. All grid resources are monitored through two Nagios instances



It has same interface as gridppnagios. Alarms from these instances goes to Operational Dashboard

http://argo.egi.eu/ is a web interface which provides availability/reliability figures and site status. It is equivalent of old myegi interface with some additional services.

I am planning to decommission both instances of gridppnagios in coming weeks. I have stopped nagios and httpd on both instances so it will not send tests to grid resources in UK. I will also decommission storage-monit.physics.ox.ac.uk which was only used for storage replication test.

We will keep vo-nagios.physics.ox.ac.uk running until we get a replacement for vo-monitoring.

Monday 13th June

  • Active Nagios instance moved to Lancaster

Tuesday 5th April 2016

Oxford had a scheduled network warning so active nagios instance was moved from Oxford to Lancaster. I am not planning to move it back to Oxford for the time being.

Tuesday 26th Jan 2016

One of the message broker was in downtime for almost three days. Nagios probes picks up a random message broker and failover is not working so a lot of ops jobs hanged for long time. Its a known issue and unlikely to be fixed as SAM Nagios is in its last leg. Monitoring is moving to ARGO and many things are not clear at the moment.

Monday 30th November

  • The SAM/ARGO team has created a document describing Availability reliability calculation in ARGO tool.
VOs - GridPP VOMS VO IDs Approved VO table

Tuesday 19th May

  • There is a current priority for enabling/supporting our joining communities.

Tuesday 5th May

  • We have a number of VOs to be removed. Dedicated follow-up meeting proposed.

Tuesday 28th April

  • 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.

Tuesday 31st March

  • LIGO are in need of additional support for debugging some tests.
  • LSST now enabled on 3 sites. No 'own' CVMFS yet.
Site Updates

Tuesday 23rd February

  • For January:

ALICE: All okay.

RHUL 89%:89% Lancaster 0%:0%

RALPP: 80%::80%

RALPP: 77%:77%

  • Site responses:
    • RHUL: The largest problem was related to the SRM. The DPM version was upgraded and it took several weeks to get it working again (13 Jan onwards). Several short-lived occurrences of running out of space on the SRM for non-ATLAS VOs. For around 3 days (15-17 Jan) the site suffered from a DNS configuration error by their site network manager which removed their SRM from the DNS, causing external connections such as tests and transfers to fail. For one day (25 Jan) the site network was down for upgrade to the 10Gb link to JANET. Some unexpected problems occurred extending the interruption from an hour to a day. The link has been successfully commissioned.
    • Lancaster: The ASAP metric for Lancaster for January is 97.5 %. There is a particular problem with ATLAS SAM tests which doesn’t affect the site activity in production and analysis and this relates to the path name being too long. A re-calculation has been performed.
    • RALPP: Both CMS and LHCb low figures are due to specific CMS jobs overloading the site SRM head node. The jobs should have stopped now.
