CVMFS Deployment Task Force of the WLCG Operations Coordination Team


The aim of this task force is to help in the full deployment of CVMFS for software and other file deployment at all sites that are used by the ATLAS, CMS and LHCb VOs. The coordination, progress reports and issues discovered during this task force are being discussed in the bi-weekly WLCG Operations Coordination meeting.


All members of the task force can also be contacted at

How to deploy CVMFS at a site

There are several guides available in the links section on how to install CVMFS at your site, especially recommended would be

  • User guide at the CVMFS homepage
  • Ral twiki with special information for sites

Please also have a look at where you can find instructions from ATLAS on how to check that CVMFS is correctly working at your site.

There also CMS specific instructions for CVMFS deployment.

Provide information about CVMFS deployment status at a site

You may check if your site is listed in the CVMFS deployment status twiki. If so and the information is not accurate please update it there. If you have already deployed CVMFS your site is probably not listed. In case you haven't deployed CVMFS and your site is not listed please add another row in the table
