Completed Actions
1. CCRC Post-Mortem Presentation
There was some discussion of Nick's presentation, attached to the agenda. It was agreed to further explore the ETC
use-cases at a later PASTE meeting, in particular the distribution of ETCs to the Tier-1s should be clarified. The slides
for DIRAC related issues will be prepared offline.
2. Production Status Report
Minutes from the production meeting are available here.
- ProcDB update - Action(01)
Gianluca is absent.
- RAL Migration - Action(04)
Andrew is almost finished the RAL migration, all files on Castor have been changed to RAL-tape in the LFC. The site
can be unbanned in the DIRAC2 CS and Castor-tape -> -tape in order to proceed with the DC06 activity. 1k pending
files are yet to be migrated and due to the low priority could be scrapped. Andrew will report next week about the
completion of the RAL migration.
- Bookkeeping prototype - Action(07)
Zoltan has started the CLI for the BK. As a result of the BK meeting it was decided to proceed with view creation in
Oracle without using AMGA.
- Monitoring framework - Action(09)
Andrei questioned what the cause of the 0% site availability report for May could be. Roberto's suspicion is that
services not useful for us (that we do not test) are creating this impression.
- Backup DMS services on lxgate34, port IntegrityDB to DIRAC3 - Action(27)
The IntegrityDB cleanup is ongoing.
- Recover data that failed to be registered in the Bookkeeping - Action(55)
Marianne is absent.
- Production Manager Guide - Action(56)
Roland is trying to work on this.
3. Production Operations Issues
Joel commented that the BK has been down for a few days now but simple restarting of services has no effect. The
VO box at IN2P3 seems to repeatedly fail with CRL related errors, Nick agreed to contact Raja to take a look at this. A
new log file checker has been successfully tested in DIRAC2 and a p5 release can now be made.
4. DIRAC3 Tasks
Nick asked when it would be possible to restart the CCRC activity. Andrei commented that this should wait until
DIRAC3 can be deployed on the production system. Stuart mentioned the need to test the updating of files status in
the Processing DB from the JobFinalization module and how to automatically resolve the situations where something
has gone wrong.
Andrei attached a list of pending tasks to the agenda page for putting DIRAC3 into production. Ricardo is working on
the installation of DIRAC3 on volhcb01.
There was some discussion of whether to begin testing of xrootd and Nick commented that currently ALICE maintain
the service on their own but we don't have the manpower for this.
The roadmap for DIRAC3 release is firstly to put the Production System in production, in parallel work will continue on
rewriting the modules with the updated workflow infrastructure and at a lower priority accommodate the new version
of PyGSI and other developments.
5. AOB
Andrei encouraged proposals for DIRAC related contributions for the upcoming ACAT conference.
