Discussion

  • Marco: GWMS 3.7.2 released, includes bugfixes for IDTOKEN support; in upcoming-testing.AI (Mat): Submit bug report for XRootD 5.1.0rc1 problem detected in VMU tests.
  • AI (Mat): Mail GridCF list about Travis CI's policy changes.
  • AI (Mat): Ask Marco Mascheroni if he's happy with the new Pilot sections for OSG Configure.
  • AI (Mat): Continue work on OSG flocking negotiator.
  • AI (BrianL): Investigate webapp frameworks and EL 8 compatibility for HTCondor CE View.
  • AI (Junheng): Investigate registry logout error.
  • AI (TimT): Add PowerPC support to EPEL HTCondor packages.
  • VPN access now required to log in to Fermicloud head node (fcluigpvm01.fnal.gov). 2FA required to access Fermi VPN. Steve Timm's suggested solution is to create a (persistent) VM for creating other VMs if that's not possible.
    Marco will send instructions on how to get access to Fermi VPN.

Support Update

  • IceCube (Mat, Derek): Stash Origin now appears to work after creating dummy SciTokens information in Topology.
    UCL stash origin needed the same fix but needs additional debugging; Derek is providing assistance.
  • JLab (BrianL): blahp status queries time out trying to populate the Slurm job status cache.
    Opened a ticket with the the HTCondor team: https://opensciencegrid.atlassian.net/browse/HTCONDOR-104
