OSG Software Team

  • OSG 3.5.33/3.6
    • xrootd-multiuser is broken for XRootD 5. Should we delay the release?
    • osg-xrootd needs to be updated to fix its use of ofs.authlib
    • Anything else we should document in the update notes?
    • AI (Carl): Rebuild condor RPM
    • AI (Mat): Add multiple config directories to HTCondor packaging
  • AI (Carl, with help from Mat): Enable networking in Koji builds
  • AI (Mat): Finish adding CVMFS to the OSG backfill container


  • kojibuilder2 (new K8s builder in the production namespace) not reporting to the koji hub.
  • GlideinWMS:
    • 3.7.3 release candidate is in testing.
    • New 3.9 release needed to fix the following bugs:, String encoding issue at, Update LDAP module for Python 3, both affect only AWS submission, not regular grid submission.

Support Update

  • Chameleon Cloud (BrianL): investigating an issue where the OSG validation script is failing so the container isn't running jobs
  • Purdue (Carl, Derek): Derek successfully removed the errant local records for Purdue; Carl will ask Purdue to re-run the custom Gratia probe he provided to them.
  • AMNH (Derek): Assisting them with SLURM configuration. Might be worthwhile to write a 'recommended SLURM configuration' document, even if it's not widely publicized.
  • OzSTAR (Marian): Assisting them with stash cache setup.

OSG DevOps

  • XRootD accounting information (from Frank):
    • May need help with automating the process of generating these reports. A month only takes a few minutes. Longer periods take much longer.
    • Table of working set, read, and re-read for monthly, quarterly, and year.


None this week

OSG Release Team

  • Need to send ready for testing email today
  • Aiming to release XRootD 5 this week, at least in 3.5 upcoming
