        Speakers: Dr Marcello Barisonzi (DESY), Dr Wolfgang Ehrenfeld (DESY)
        ATLAS Support: Period from June 13th to August 7th (Wolfgang Ehrenfeld): ------------------------------------------------------------------------ - storage o lustre still full, moved some users to SONAS, will deplay for all ATLAS users when Yves is back - software o cvmfs problem (27.6.2012): too large catalog for cache size -> solved by extenting cache partition to now recommended size of 10 GB (for Grid). Not clear why so much catalog information is accessed on WN. Can we diagnose this with the help of ATLAS the next time, if it reoccurs? - operations: o power outage seen by users, thanks for the user notification and work to get the NAF running again o no login possible due to full /tmp on prefered WGS (25.6.2012)
