Description

The talk presents the experience gathered during the testbed administration (~100 PC and 15+ switches) for the ATLAS Experiment at CERN. It covers the techniques used to resolve the HW/SW conflicts, network related problems, automatic installation and configuration of the cluster nodes as well as system/service monitoring in the heterogeneous dynamically changing cluster environment. Techniques range from manual actions to the fully automated procedures based on tools like Kickstart, SystemImager, Nagios, MRTG and Spectrum. Booting diskless nodes using EtherBoot, PXEboot is also investigated as a possible technique of managing Atlas Production Farms. Kernel customization techniques (building, deploying, distribution policy) allow users to freely choose proffered kernel flavors without sysadmin intervention. At the same time administrator retains full control over entire testbed. The overall experience has shown that the proper use of the open-source tools addresses very well the needs of the ATLAS Trigger DAQ community. This approach may also be interesting for addressing certain aspects of GRID Farm Management.
