LCGSCM

Internal meeting for host laboratory LCG service providers focussing on issues on a timescale of ~1 week to ~1 month.

Mailing list: lcg-service-coordination-meeting@cern.ch

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?
      • 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.

        5 June - a meeting with CMS computing management has been setup for 19 June to discuss this and other service-related issues. An IT pre-meeting was held 5 June - notes attached.

      • LFC for LHCb - replication to additional Tier1 sites
        We agreed to finish the setup of the LHCb r/o LFC replica at all LHCb T1 database clusters during the next two weeks. This will allow the LFC teams at T1s to setup the LHCb LFC front-ends independently and connect to the local DB replicas (in the LHCb cluster). Eva will pass around a concrete plan in the next days.
      • Status of experiment use of 3D services

        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...)
