OSG Software Team

  • Please review the next triage rotation starting Sep 30
  • OSG 3.4.35/3.5.1
    • AI (Diego): Apply bosco override patch to HTCondor 8.8.5 in OSG 3.4 (SOFTWARE-3816)
    • AI (Diego): Release stashcache-client (SOFTWARE-3799)
    • AI (Mat): Add support for boscocluster override in osg-configure v2 (SOFTWARE-3818)
  • AI (Mat): Coordinate with Marco, Jeff, and Judith for the Hosted CE git repo and config management
  • AI (Carl): Replace HTCondor blahp external with the "OSG version" in the HTCondor 8.9 series
  • AI (Carl): Issues with Gratia 1.2.10 need to be fixed (SOFTWARE-3737)
  • AI (Edgar): Test the latest Stash Cache image (SOFTWARE-3810)

Discussion

  • Marco intends to release GlideinWMS 3.5.1 today so that we can test it in OSG 3.4 and 3.5
  • We discussed the short-term plan if we find an issue with the latest Bosco tarballs:
    • If it's an issue with the compiled code, the tarball needs to be rebuilt
    • If it's an issue with the scripts, Operations will maintain patches

Support Update

  • Brown (Marian): They're still working on setting their storage.xml properly to join CMS AAA
  • CNAF (Edgar): Troubleshooting authorization failures for authenticated Stash Cache
  • CyVerse (Carl): Running into issues with 32-bit depsolving on upgrade
  • Harvard Medical School (Mat): They can actually get user accounts from Harvard so they don't need to use the OpenID-issued certs
  • LHCb (Derek, Carl): LHCb pilot records show up as other_egee but the raw record doesn't contain this anywhere
