A comment had been sent by email prior to the meeting.  There were no further comments. The minutes were approved by the WLCG MB.

1.2         Date of meetings in 2010

The dates of MB meetings in Indico (http://indico.cern.ch/categoryDisplay.py?categId=666) can be considered as firm dates.

1.3         Dates for next WLCG Collaboration workshop and associated events

Proposed dates are 7-9 July at Imperial College, UK - to be confirmed at the next F2F meeting. An Indico agenda entry has been created at http://indico.cern.ch/confRegistrationFormDisplay.py/display?confId=82919. Experiments intending to hold a jamboree are requested to contact Jamie Shiers.

1.4         High Level Milestones

Feedback is requested on the High Level Milestones linked from this meeting’s agenda page prior to the next F2F meeting.

 

2          Action List Review (List of actions)

 

·         OPN Mandate: Experiments and some Sites should provide names for working with the OPN on the needs and actions needed on Tier-1 to Tier-2 links.

Names are requested prior to the OPN meeting on 8 March (http://indico.cern.ch/conferenceDisplay.py?confId=80755).

Those with input on ESNET connections to T2 sites in the USA should contact the OPN group.

 

3          LCG Operations Weekly Report  
 

 

Summary of status and progress of the LCG Operations. This report covers the WLCG activities since the last MB meeting. All daily meeting summaries are available here: https://twiki.cern.ch/twiki/bin/view/LCG/WLCGOperationsMeetings. Some comments on the slides are noted below.

 

Slide 4: the difference in ticket numbers between ATLAS and CMS could be related to working methods. Daniele Bonacorsi clarified that to compare CMS with ATLAS one would need to take GGUS+Savannah for CMS and GGUS for ATLAS. A GGUS-based comparison is not enough.

Slide 6, 4.2:  This is now fixed.

Slide 10: ASGC are requested to provide a SIR.

Slide 11, last bullet: the tape is part of a HSM (not a backup).

Slide 13: It was confirmed that the bi-weekly WLCG service coordination meeting will address rollout of version changes.

 

 

4           LCG-LHCC Referees & C-RSG Meeting

 

This joint meeting will take place on Tue 16 Feb. As stated on its agenda (http://indico.cern.ch/conferenceDisplay.py?confId=80461), we must consider that there will be accelerator running in 2011 - we need to construct a realistic scenario. The experiment reports need to include resource planning for 2011. This will be used as input to the RRB. If the speakers indicated on the agenda need to be changed please inform I. Bird.

 

 

5          GDB Summary

 

J. Gordon presented a summary of the GDB meeting held at CERN on 13 Jan 2010. His slides are linked from the agenda of this meeting. He welcomed suggestions for topics for the GDB scheduled for March in Amsterdam as well as for the next pre-GDB. Jamie suggested talks on remote operations, benefitting from the NL-T1's experience in this area with their remote (30km) site.

 

 

1          AOB

 

 

1.1         WLCG Risk Assessment

The last WLCG risk assessment, linked from the agenda of this meeting, dates from 2003.  I. Bird requested that the MB members review the 2003 risk assessment and provide suggestions for updates.

1.2         FTS support for non-SRM SEs

M. Schulz: The FTS modifications required to support non-SRM-SEs are minor and we can implement these changes within a few weeks. 

It should be noted, that a SE that solely provides a gridFTP interface is only a valid deployment scenario for small T3 sites. T1s and T2s definitely require the flexibility and space management capabilities provided by SRM.  

 

 

2          Summary of New Actions

 

There were no new actions.
