Done - (27) - 08/01/08 - Andrew - Backup DMS services on lxgate34 to allow migration to SLC4, port IntegrityDB to DIRAC3
1. CCRC operations issues
- volhcb01 status
volhcb01 installation is now completed, all WMS services are running and this can start to be tested with real jobs. A
tagged DIRAC3 release is now available and will be used for the next week. It was agreed to increment the tag patch
level if any bug fixes are required. There was also some discussion regarding the LCG site names that have been
transferred from DIRAC2 by Vladimir, some can be cleaned up. Andrei suggested Vladimir could take a look at
automatic publishing of site information from the BDII using the GOCDB site name as a primary key. ( ACTION:
Vladimir )
- Resources description
The new structure e.g. /Resources/Sites/LCG.CERN.ch allows to better organise the Grid components we class as a
site e.g. CE, SE, FileCatalogs etc. There was some discussion of the existing T1-disk and T1-tape definitions, Andrew
confirmed that since the SE name in the LFC is not used any more there is no inconsistency for the DC06 data. The
usage of Tier-2s for analysis and as failover SEs was raised, it was agreed to postpone discussion on the analysis front
and for the failover SEs it was decided to leave Edinburgh for testing the mechanism. There is an ongoing CS cleanup
triggered by the reorganisation of the Resources section, in particular the SiteLocalSEMapping is no longer needed and
several components will be affected.
- Authorization description
See document attached to agenda page. Andrei agreed to flesh out this proposal as a document including the
interaction with VOMS.
- Generic Pilot run
See document attached to agenda page. Stuart raised the point that for CNAF there is a non-standard configuration
of LSF that results in an incorrect TimeLeft estimation. The filling mode is almost all in place and this will be fixed
prior to the proposed run. The pilot agents DB will be used to track the history of pilots by reference. Roberto
questioned whether to convey the lhcb_pilot role to the sites, Andrei advised to wait until the official endorsement of
the MB.
2. DIRAC3 tasks
See tasks document attached to agenda page, items marked <Production> will be pursued with a high priority before
the production release. MC Simulation, Reconstruction and Stripping tests will continue as part of the commissioning.
Nick asked about the timescale for the CCRC restart and Andrei suggested this will be possible by the end of the
week.
3. AOB
Joel raised the question from yesterday about the IntegrityDB. Andrew confirmed the contents had been processed
and some files were removed from the LFC and storage such that the DB was empty and could be retired.
