WLCG Operations Coordination: CVMFS Deployment Status

This report outlines the status of the CVMFS (Cern Virtual Machine File System) deployment as of December 2012. Version 2.1.5.beta has been released, enhancing NFS support and shared cache capabilities, though the NFS feature is advised for emergency use only. The document highlights the collaborative efforts of the four Virtual Organizations (VOs)—Alice, ATLAS, CMS, and LHCb—in promoting full CVMFS deployment at all supporting sites. Initial deployment statistics reveal that ~120 sites have CVMFS supported. A target for deployment by the end of April 2013 has been established, ensuring that the latest software versions will only be available in CVMFS.
