Deployment and Operational Experiences with CernVM-FS at the GridKa Tier-1 Center
Manfred Alef, Axel Jäger, Andreas Petzold, Bernhard Verstege · Journal of Physics Conference Series · 2012
In 2012 the GridKa Tier-1 computing center hosts 130 kHS06 computing resources and 14PB disk and 17PB tape space. These resources are shared between the four LHC VOs and a number of national and international VOs from high energy physics and other sciences. CernVM-FS has been deployed at GridKa to supplement the existing NFS-based system to access VO software on the worker nodes. It provides a solution tailored to the requirement of the LHC VOs. We will focus on the first operational experiences and the monitoring of CernVM-FS on the worker nodes and the squid caches.
