Discussion

  • There will be upcoming changes to Freshdesk SLAs and policies; exact details to come later.
  • XRootD 4.12.5 release is out.
  • Derek: LIGO dataframe access with SciTokens is at a roadblock because LIGO shares an origin with CMS; LIGO wants TLS enabled but CMS is not ready for it. LIGO will move to their own origin server.
  • AI (Diego): Continue building XRootD 5 plugins for EL8, and updating xrootd-multiuser.
  • AI (Edgar): Push xrootd-standalone and x509-scitokens-issuer over the finish line

  • AI (Mat): Document building xrootd-compat packages; build Ubuntu containers.

  • GlideinWMS: 3.7.1 work continuing. 3.6.5 released recently and has been stable in production. Jeff having trouble restricting disk usage on a site; Marco will debug and seek help from HTCondor developers.

Support Update

  • Expanse (Edgar, BrianL): Tracked down some EL8 Bosco incompatibilities. These fixes need to be included in Bosco override files until they're fixed upstream.
  • JLab (Derek): JLab Origin much more stable this week. Continuing to aggressively monitor, but so far so good.
  • OSG Connect (Derek): StashCP issue when the writeback address is a directory and not a file. Curl doesn't give an error message, it just gives a non-zero exit code. So the error from stashcp is cryptic. Will investigate solution.

OSG Investigations Team

  • Elasticsearch on Kubernetes!
  • Elasticsearch upgrade upcoming on OSG GRACC coming the end of this month.
