Support Update

  • Georgia Tech (BrianL): Gave them some AP HTCondor config that should prevent pilots from flocking out to pilots
  • Lancium (BrianL, Mats): live backfill container debugging session that uncovered issues in the periodic health check not properly detecting unpriv Singularity.
  • Multiple (Derek): Several sites had failed gratia probes over the last week. All isolated events, but I think there were 4 at the same time.

OSG DevOps

  • Elasticsearch will need to be updated. Working on a schedule.
  • StashCP go client is working and tested, and being tested by Christina now. Need to talk to Mats on packaging and releasing. (will follow up). No news from Christina,
  • Design document is done and is being distributed for xrootd monitoring collector NG (next gen). Shoveler is working and lightly tested. Collector is 50% done. Design document is still not reviewed, but moving foward anyways.
  • XRootD TCP plugin is ready for packaging. Derek will follow up with software team on who to hand that off to.
  • Discussions of xrootd-multiuser support for checksumming on-the-fly. After a discussion, the checksum-on-the-fly funcationality will be ported to xrootd-multiuser. Copied largely from xrootd-hdfs. This does mean that out-of-order writes will not be supported.
  • More partners are asking about scitokens-cpp, and compatibility. Expect some updates.

    • Maybe we have been doing tokens wrong? Use the `typ` rather than `ver`.
  • (Stalled, but need to get back to it) XRootD accounting information (from Frank):

    • May need help with automating the process of generating these reports. A month only takes a few minutes. Longer periods take much longer.
    • Table of working set, read, and re-read for monthly, quarterly, and year.
