Discussed topics:
1. There is now an online monitoring of memory, disk and network usage of the batch farm machines (W. Schoen)
See http://lxdv42.gsi.de/torrus/linux
2. grid1 xrootd cluster: files cannot be opened with TFile::Open any more since a few weeks. This makes it impossible to read them via AliRoot while they are on xrootd. The problem appeared at the beginning of May and needs to be solved.
3. both grid1 and gsiaf xrootd are of a version which is incompatible with the new AliEn 2.13. Therefore it is impossible to configure them as AliEn storage elements as they are. They need an upgrade to the new xrootd before. Files stored there should not be a concern, they will be recognized by the new xrootd.
4. because of point 3., no progress was made on copying PDC06 events to GSI. This topic was presented in an email to Federico and Co. (by Kilian). Both Andreas and Latchezar suggest as solution to have a GSI SE and make the copy inside AliEn. In this fashion there is no further need for a stage pool.
The topic was also discussed at the LCG task force meeting on Thursday May 24, 14:00. The solution with the SE will be tested as soon as possible by Kilian.
5. no progress on PROOF installation
6. request for activating the "locate" command (database is there but not accessible)
