1. Action Updates
- Action(07) - Prototype Bookkeeping
Zoltan is back on Wednesday.
- Action(09) - Virtual Control Room
SAM test status now being reported weekly to the Tier-1 sites (to explain low results). SAM test visualization for the
Tier-0, Tier-1 and Tier-2 sites via the Dashboard is pending. The Tier-1 VO-box test will be integrated into this suite.
The Google calendar is in place, Stuart suggested categorizing the items via Tier and downtime time e.g. scheduled,
unscheduled. There was some discussion regarding the procedure for banning and unbanning sites, Andrei agreed to
add a comment field and Joel agreed to formulate the procedure. ( ACTION: Andrei, Joel )
- Action(57) - Automatic publishing of BDII information in the CS
It was mentioned that some sites are presenting inconsistent information in the BDII / GOC DB Roberto agreed to go
over this with Vladimir. ( ACTION: Roberto )
- Action(62) - Check whether glite 3.1 comes with requested features/patches & coordinate upgrades
Roberto will send a summary via mail.
- Action(63) - DIRAC3 scripts for adding new users to the VO + CS + LFC registration
Roberto found some problems with this script and is in the process of converting it to python.
- Action(64) - Preprare SRMv1 retirement plan
This was compiled and is attached to the agenda. It was agreed to update the attached plan with the changes as
discussed during the meeting.
- Action(69) - Single user account for SGM user
Joel is proceeding through the sites requesting single accounts for SGM users.
- Action(70) - DIRAC3 installation in the LHCb release area at CERN
It was agreed to enable write permission to the DIRAC configuration file for the DIRAC developers in case of
emergencies.
2. Production Issues
The DIRAC2 test machine (lxgate03) and DIRAC2 DMS (lxgate34) can now be retired.
There was some discussion regarding the communication between the Operations team and the DIRAC developers and
it was suggested to clean up the old Savannah page. Joel commented that there was a very old DIRAC Savannah
project that can be used for this and confirmed that the administrators from the DIRAC2 project are added there.
- Report from the Production meeting
Stuart mentioned that the BK replica flag was not set in recent tests, after setting the status of the BK catalog to
'Active' there were problems with normal put and register operations, e.g. all putAndRegister operations try to set a
'has replica' flag in the BK catalog. After some discussion it was agreed to pursue a temporary solution of changing
the configuration setting of BK to 'InActive' in the CS by default ( ACTION: Andrei ). A feature request should be
formulated to afford this option in the constructor of the Replica Manager in the future. Recent SAM jobs at CERN
cannot write into shared area, ongoing issue being debugged.
- Ancestor file treatment at job creation, submission
Tests are ongoing and this will be discussed presently. It was noted that not all of the Tier-1 '-tape' SEs are defined in
the CS, these will be added immediately.
- DIRAC host aliases
It was agreed to take the list of updated aliases from last week and allow these as soon as possible. ( ACTION: Joel )
- DIRAC2 distribution with recent fixes in modules, SRMStorage
There was some discussion on the recent reversion of CVS commit privileges that is still not understood. It was
agreed to commit the recent changes to DIRAC2 and make a release.
3. DIRAC3 Tasks
- Workflow module coding conventions
Discussions will continue via mailing lists.
- Job creation strategy in the Production DB
Creation and submission strategy of jobs has changed after recent ancestor file considerations. Population of the
ProductionDB from the BK / LFC information vastly reduces the risk of inconsistency.
- Application software description in CS
Command line tools should be created to manage the list of LHCb software. ( ACTION: Stuart, Vladimir )
