Hi Catalin,

I prefer the gridpp.ac.uk simply because these are truly regional VOs (there won't be any e.g. northgrid in London), but given the small user base and scope of these VOs we should just go ahead with whatever is easiest to setup.

Hi,

Following a short email exchange with Alessandra re: CVMFS space for vo.northgrid.ac.uk, it emerged the idea to create and maintain a (small) CVMFS infrastructure that would serve mainly the UK regional VOs (vo.southgrid.ac.uk vo.northgrid.ac.uk vo.scotgrid.ac.uk vo.londongrid.ac.uk) separated from the 'egi.eu' CVMFS domain configuration.

One option would be to keep them under the already existing (and configured everywhere in the UK, so no extra work needed!) 'gridpp.ac.uk' CVMFS domain (just to decide on the repo names i.e. /cvmfs/northgrid.gridpp.ac.uk or /cvmfs/north.gridpp.ac.uk or /cvmfs/vo.northgrid.gridpp.ac.uk or /cvmfs/vo.north.gridpp.ac.uk).

But also a new CVMFS domain 'ac.uk' could be defined (but which would need some extra work for implementation and configuration at participating sites) with more suggestive repo names i.e. /cvmfs/vo.northgrid.ac.uk or /cvmfs/northgrid.ac.uk

In any case RAL could act as Stratum-0 and Stratum-1 for these repositories, but probably we'd need another UK site to volunteer to host a Stratum-1 for failover purposes.

As there are already requests to setup repos for londongrid and northgrid VOs already, this needs to be discussed and decided asap, via email or maybe today's Ops meeting?

Let me know of your opinions!

Regards,
Catalin
