National Squid service for CVMFS

If you are going to run jobs on your cluster using CernVM-FS you should also use squids to cache data at your site. In case you decide to not install a squid service at your site or in case of failover at your site, Italian NGI provide a National squid service accessible only by registered italian sites.

We have two squids with ACLs based source and destination. If you decide to use this service, please open a ticket through XGUS providing:

  • the network information of your WNs (eg 131.154.101.0/255.255.255.0);
  • the cvmfs server(s) your WNs need to contact (eg: cvmfs-gridit.cnaf.infn.it);
  • add the line CVMFS_HTTP_PROXY="http://squid01.cnaf.infn.it:3128|http://squid02.cnaf.infn.it:3128" to the configuration of the cvmfs client on each WN (usually under /etc/cvmfs/config.d/).

Eg. for VO gridit: /etc/cvmfs/config.d/gridit..conf:CVMFS_HTTP_PROXY="http://squid01.cnaf.infn.it:3128|http://squid02.cnaf.infn.it:3128"

Using National Squid service for failover

If you run local squid service, you can also add the national squid servers for failover case. CVMFS_HTTP_PROXY is used to specify the squid server(s) to be used for local caching. It supports both load balance and failover:
