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.
