ATLAS report

(https://indico.desy.de/getFile.py/access?subContId=0&contribId=3&resId=minutes&materialId=minutes&confId=5954)

Lustre space tight -> waiting for SONAS
first tests of CVMFS no real issues so far
AFS problems:
- list of volumes with high load provided by NAF used to contact users
- for software versions difficult to identify users triggering the accesses
- unclear if ATLAS is following the correct way to create/replicate volumes
unanswered tickets: rt#430845, rt#431007(SGE)
will switch to CVMFS on 14.05.12 for ATLAS software

CMS report

first SONAS tests successful, performance similar to Lustre, but stable
Lustre and dCache user space full

ILC/CALICE report

nothing to report
