CernVM-FS Stratum-0 for non-LHC VOs

Note: Old page (mainly related to gridpp.ac.uk CernVM-FS domain) can be found here ([1]).

RAL Tier-1 is currently maintaining two CernVM-FS domains (egi.eu and gridpp.ac.uk) that include 24 CernVM-FS Stratum-0 repositories for non-LHC VOs and projects (auger, biomed, cernatschool.org, chipster.csc.fi, dirac, galdyn, comet.j-parc.jp, glast.org, hyperk.org, km3net.org, ligo, vo.londongrid.ac.uk, lucid, mice, na62.vo.gridpp.ac.uk, vo.northgrid.ac.uk, pheno, phys.vo.ibergrid.eu, vo.scotgrid.ac.uk, snoplus.snolab.ca, vo.southgrid.ac.uk, t2k.org, enmr.eu).

The Stratum-0 v2.1 repositories are replicated by dedicated EGI CernVM-FS Stratum-1 servers located at RAL, NIKHEF, ASGC and TRIUMF.

The following instructions will refer to configuration under egi.eu CernVM-FS domain.

Setting up a site to access small VOs CernVM-FS repositories located at RAL

Assuming that your site is already supporting CernVM-FS (client v2.1.X) for LHC VOs, one only needs to update / install the cvmfs-keys package to the version 1.5-1 ([2]) on the worker nodes. This package adds the public keys and Stratum-1 server addresses for the egi.eu and opensciencegrid.org domains (no changes for the *.cern.ch repositories).

In addition, one must specify in /etc/cvmfs/default.local the names of the local site squids:

CVMFS_HTTP_PROXY="http://first.squid.domain:3128;http://second.squid.domain:3128"

The last requirement is that the site local squid(s) are configured to use the Stratum-1 servers at RAL, NIKHEF, ASGC and TRIUMF (see /etc/cvmfs/domain.d/egi.eu.conf for the server names).

Also do not forget to define the following environment variables on the batch farm (Note - you need to define them only if your site supports the specific VO):
