Discussion

  • AI (Junheng): work on osg-notify bug-fix
  • AI (Mat): OSG-Configure tasks promised to the GlideinWMS team for the end of November.
  • GlideinWMS
    • Mat found a GlideinWMS bug when working on Ubuntu support; Marco to review and merge, which should get us further along since the affected script is pulled from the master branch
    • 3.7.1 got promoted to production.
    • Working on merging the changes to the Python 3 version.
    • UCSD factories are both running the 3.7 series.
    • CERN factory still running 3.6 series.
    • 3.7.2 expected to handle missing GSI infrastructure.

Support Update

IceCube (Mat) - playing whack-a-mole with Stash Origin issues (docs have already been improved as a result). Currently investigating permission issues that are likely in the XRootD configuration layer.

OSG Investigations Team

BrianB has made quite a bit of progress on the OS pool registry:

  • Almost has an end-to-end proof of concept working in the osgdev namespace on Tiger
  • Put together a development container so that work can be handed off

Discussion

AI (TimT):

  • Build HTCondor 8.8 and 8.9 in OSG & run VMU tests
  • Talk to Horst about testing XRootD 4
    Difficult to find to find willing testers for XRootD 4 since XCache servers are all using XRootD 5
    on the other hand, non-XCache servers are reluctant to upgrade; talk to Dave Mason for help.
  • Look at EL 6 retirement spreadsheet
  • Move cronjobs from ingwe to moria
