Minutes
    • 10:00 → 10:20
      Outstanding Issues & Actions 20m
      • Cleaning of databases prior to multi-VO tests
        On several occasions, the database behind various services have needed to be "cleaned" to prevent performance degradation. This has applied to CASTOR DBs, FTS, dCache etc. Have all the necessary cleaning operations been performed at CERN and outside sites ready for the multi-VO throughput tests starting March 26th? Should these operations be performed regularly? Automatically?

        20th June - needs to be extended to cover also defragmentation and other house-keeping isues.

      • Experiment servers / services: status
        See CMS task force of Sep 20 and this wiki

        Also affects ATLAS "Tier1" VO boxes that are being setup / tested at CERN.

        9 August - task force has been setup and has met once. Notes are attached.

        wiki page

        The primary purpose of this item is to bring up any (hopefully rare) issues that are in danger of becoming "hot" if not given attention.

        By definition, this must be used sparingly (i.e. not for every single problem seen by an experiment) and experience has shown that these issues should be raised in advance, e.g. the day before (or even earlier if possible...)
