None this week

Support Update

  • Hosted CEs (BrianL, Mat): ran into issues with %ghost dirs in osg-configure not being created in the version of RPM available on EL9 (and maybe EL8?)
    • Fix: Explicitly add ghost directories to file list
    • Issue may occur in other packages as well
  • Emails (BrianL): Google and other email providers are starting to get stricter about SPF records meeting RFC requirements. We are getting bitten by the 10 DNS lookups in the SPF record max. Freshdesk alone uses 10.
  • XRootD (Matt W): New upstream might fix long-running JLab issue

DevOps

  • Derek: Profiling performance of XRootD monitoring shoveler, DNS lookups and logging found to be a choke-point
  • Derek/BrianL: Configure a new Traefik instance
  • GRACC conversion to Tiger OpenSearch is ongoing.
  • Derek did some profiling and optimization of xrootd collector: https://derekweitzel.com/2024/01/31/profiling-xrootd-collector/

OSG Release Team

  • Ready for Testing
    • osg-configure, frontier-squid, voms, vault
    • frontier-squid is high priority, contains a number of CVEs
  • Ready for Release
    • Nothing yet
  • Outstanding question: how to announce Pelican releases
  • Discussion topic: Running OSG tests prior to promoting daily condor releases
    • The current config supports this, osg-development already pulls from condor daily repos
