OSG Software Team

  • Kubernetes Hackathon today!
    • AI (Carl): Make CronJob for fixing up user GIDs in COManage.
    • AI (Mat): Investigate auto-update failures in the PATh facility Kubernetes pool.
    • AI (BrianL): Move FE cert-manager patches to base
    • AI (BrianL): Investigate upgrade path from Flux v1 to Flux v2
  • Doc focus this Friday
  • Primary MkDocs repositories being moved to the osg-htc GitHub organization. Technology first, then docs
  • AI (BrianL): Work with JeffD to debug site failures starting after OSG 3.6 upgrades.
  • AI (BrianL): Respond to Scott Koranda regarding missing EPPNs in COManage.
  • AI (Carl): Remove certinfo usage from Gratia.
  • AI (Mat): Renew central collector host cert (which expires on May 6); UNL SANs are no longer necessary.
  • AI (Mat): Register PATh Facility Execute Points in Topology.
  • AI (TimT): Test HTCondor 9.9.0 in CHTC; new remote management features might impact glideins so those will need extra testing.
  • Next projects:
    • Transition contacts to COManage
    • Finish sending OSPool StartD logs to the GRACC
    • Streamline deployments of OSDF caches and origins
    • Retire OSG 3.5
    • Allow for custom workflows in opensciencegrid/images


Added a "contrib" directory to the opensciencegrid/images repo so people can contribute images; the first contributor was FNAL with some FTS images. There is a danger of the GitHub Actions for the repo taking too long; the Software Team will investigate fixes as necessary.

Support Update

  • BNL (Derek): Debugging various randomly occurring slow or failing transfers with XRootD-Standalone
  • GRACC (Derek): Debugging CEs that have stopped reporting to GRACC after upgrading to OSG 3.6; will stay in touch with the Software Team regarding necessary software/packaging/documentation fixes resulting from these.
  • GIL (Carl): Debug Igor's issue with viewing Topology resources using his COManage credentials.

OSG DevOps

  • A few feature requests / bug fixes for StashCP.
  • Still helping shoveler support for token auto-updating.
