RAL Tier-1 is currently maintaining two CernVM-FS domains (<code>egi.eu</code> and <code>gridpp.ac.uk</code>) that include 24 CernVM-FS Stratum-0 repositories for non-LHC VOs and projects (<code>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</code>).

Stratum-0 v2.0 repositories are replicated on the local LHC Stratum-1 server. Stratum-0 v2.1 repositories are replicated by the dedicated EGI CernVM-FS Stratum-1 server located at RAL.

The Stratum-0 v2.1 repositories are replicated by dedicated EGI CernVM-FS Stratum-1 servers located at RAL, NIKHEF, ASGC and TRIUMF.
 +
 
 +
<!-- At the moment (1 August 2015) the repositories hosted at RAL are published under two identical CernVM-FS spaces i.e. <code>/cvmfs/<repo_name>.gridpp.ac.uk</code> and <code>/cvmfs/<repo_name>.egi.eu</code>. Similarly the Stratum-1 services (except TRIUMF) are replicating both <code>gridpp.ac.uk</code> and <code>egi.eu</code> domains. The plan is to retire the <code>gridpp.ac.uk</code> domain by very early 2015.

The following instructions will refer to configuration under <code>egi.eu</code> CernVM-FS domain.

Assuming that your site is already supporting CernVM-FS (client v2.1.X) for LHC VOs, these are the configurations needed to access the na62, mice, hone, wenmr, phys-ibergrid, hyperk, t2k, glast and cernatschool CernVM-FS areas.
+
Assuming that your site is already supporting CernVM-FS (client v2.1.X) for LHC VOs, one only needs to update / install the <code>cvmfs-keys</code> package to the version 1.5-1 ([https://cvmrepo.web.cern.ch/cvmrepo/yum/cvmfs/EL/5/x86_64/cvmfs-keys-1.5-1.noarch.rpm]) on the worker nodes. This package adds the public keys and Stratum-1 server addresses for the <code>egi.eu</code> and <code>opensciencegrid.org</code> domains (no changes for the <code>*.cern.ch</code> repositories).
  
−
On each worker node create the <code>/etc/cvmfs/domain.d/gridpp.ac.uk.conf</code> file
+
In addition, one must specify in <code>/etc/cvmfs/default.local</code> the names of the local site squids:
  
 
<pre>
 
<pre>
−
[root@lcg0999 ~]# cat /etc/cvmfs/domain.d/gridpp.ac.uk.conf
+
CVMFS_HTTP_PROXY="http://first.squid.domain:3128;http://second.squid.domain:3128"

+
 
</pre>
 
</pre>
−
<!--
+
 
 +
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 <code>/etc/cvmfs/domain.d/egi.eu.conf</code> for the server names).
 +

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):

VO_AUGER_SW_DIR=/cvmfs/auger.egi.eu
