This is part of the core operations team activites

The task involves:

1. Tracking new VO requests across the Grid and specifically those affecting UK resource providers.

2. Maintaining the extracts and details at: http://www.gridpp.ac.uk/wiki/GridPP_approved_VOs.

3. Tracking the status and problems experienced by the VOs and raising issues to the weekly ops-team meeting - Site enablement problems - User issues

4. Providing (or coordinating) help and support to new VOs who require guidance on becoming grid enabled.

TODO list

* Good practice
 * For individual users of regional VOs
 * for medium sized VOs
 * An example data model
  - Use checksums
  - Custodial copies of data  
  - Keep multiple copies for load sharing and resilience
    - Sending jobs to data
  - Catalogue synchronisation (Use LFC)
    - Sensible paths on storage

* VOMS
  - Resilience
  - Use of roles
  - Use of SaroNGS (aow obsolete)

* How to do stuff
 - Submitting jobs to data

 * Job submission

* Ganga
 - Stuff for small VOs. 

* Dirac

Comments to Chris at HEPSYSMAN: - reliability - easy of use - future proofing - LHC VOs dictate directions (e.g. move to CREAM, away from LFC) - WLCG stack is not complete (holes for data management etc.) - Hidden features .... https://wiki.egi.eu/wiki/VO_Services/Services_and_Tools_Portfolio (found via Diane Ganga) -- try not to lose portal and console developments in NGS (worked better with gram on CEs) -- free to support SARONGS in the UK - Had ngs for a long time but little real work submitted. Should NGS sites have UI point at GridPP WMSes? - Config changes break things inc. certificates. VO specific tests. What is Nagios support like for multi-VOs? - Manage VO expectations - Site admins need to be proactive -> raising VO issues to say TB-SUPPORT or proxy GGUS tickets - What about other solutions like boinc? - Typical use cases - should VOs define this when joining? - Repository of images for middleware. UI. Use of CVMFS. -- Observation of people taking up instructions (feedback). Config UI is complicated. Open UI? UI with GSI ssh route - but then who to support?
