    Description
    Bi-Weekly LHCbDirac DevOps meeting
    Hide

    Present: Chris, Zoltan, Joel, Vladimir, Federico, Luca, Zoltan
    Remote: Andrei, Milosz

    Apologies:

    Minutes/matters from last meeting

    Update of the MySQL db: (https://its.cern.ch/jira/browse/LHCBDIRAC-656)   The Certification DB will not be yet updated, since we are still not based on v6r18.

    DNS DDOS from lbtestvobox: fixed by restarting the nslcd daemon

    Vobox root login: still not clear why Federico can login as root. To be added to the list: Zoltan, Philippe, Federico.

     

    LHCbDIRAC installation: Status of servers, DBs, build machines…

    runsv on system: (https://its.cern.ch/jira/browse/LHCBDIRAC-697) the task should be moved to DIRAC since it concerns everyone. New installations should be easy, but existing one will need a clear procedure. The proposition is to move the binaries from Linux directory to sbin: try to change it in the External tarball. Will require modifying the bashrc to include sbin in the PATH

    dirac.cfg and bashrc in puppet: (https://its.cern.ch/jira/browse/LHCBDIRAC-696) This is now high priority and expected for next week. There should also be an entry in the DIRAC wiki

    Update of MySQL password (https://its.cern.ch/jira/browse/LHCBDIRAC-669): Agreed on the procedure. Will be done as soon as the dirac.cfg is deployed via puppet

    Build machines: 2 new CERNVM to run jenkins tests

    DIRAC/LHCbDIRAC Releases planning and installation

    Reminder: documentation

    Reminder: CS cleaning

    LHCbDIRAC v8r8: LHCbDIRAC went with the bundle of 05-23 but with lhcbgrid v12r0 (which corresponds to the bundle 05-30). This inconsistency should be fixed. Since we cannot, in a realistic time, certify all the goodies from 05-30, we downgrade LHCbGRID to the one matching 05-23. This is to be done in LHCbDIRAC v8r8p1

    Qt5: It seems very complicated to have QtWebEngine installed by SFT. In any case, it is used only by the bkk_gui to open log files. It was agreed to give up that, and just open a local web browser to show the logs. Once this is implemented, we are not blocking anymore gcc6.2

    Conferences planning and reports

    Database workshop at CERN:  Mostly on Conditions DBs. Everybody uses Oracle.

    Nordugrid conference: Andrei giving a talk. He can raise points about ARC, so if we have idea, we should pass it on.
