and Hartmut Stadie. All participating members voted for the suggested
one option choice: Hartmut Stadie as chair and Wolfgang Ehrenfeld as
co-chair. The NUC thanked Wolfgang for all his effort over the last
two year and wishes Harmut good luck for the next two.


2. Status report:

Status report was given by Kai. See the agenda for the report. Below a
few highlights from the discussion are listed:

 - AFS scratch

New hardware is finally order and should arrive within a few weeks time.

 - SGE priorities

Changing priorities within am experiment for the SGE batch system is
now possible via dedicated unix groups. Groups are administrated by the
experiments, priority is administrated by the NAF admins. Currently,
SGE does not allow for hierarchical administration.

 - scratch deletion tool

Deleting files using mtime is not an option for the
experiments. Wolfgang will arrange for a discussion with the experts
to make progress on this issue.

 - SL5.5:

tcx01f has been set up for SL5.5 beta. Please test as soon as possible
and give feedback. The NAF will announce this to the NUC mailing list.

 - Lustre client stability

Lustre 1.8.3 is out and currently under testing on a few systems.


3. Action items:

Some updates to the action items where presented in the status
report. Corresponding action items were closed. 


4. Feedback from the experiments:

The experiments presented their support request from last month. See
the agenda for more details.

 - One of the ATLAS Lustre instances was full. The NAF should check
   how this is monitored and when experiments are noticed.

 - ILC would like to increase they Lustre space. The NAF should
   present the technical constraints next meeting. Hartmut and
   Wolfgang will talk to Volker Guelzow about the resource
   constraints.


5. Current practise for announcements:

Nobody object to go for the combination of TWitter, experiment user
mailing lists and naf-announce mailing list. The current practise and
improvements from the NAF side was already presented in the status
report.

The NAF admins will announce TWitter to the users and describe its
use.


6. AOB:

It seems that September is a good month for the face to face
meeting. Wolfgang will try to organise a good date.
