Reminder: topology and especially downtime updates should be considered high priority. Please watch the topology GitHub repo.

Carl is working on automation but is out all this week so it might take a while before it's ready.



Support Update

  • Edgar working on a HTCondor-CE ticket for Rice but needs help; Marian may be able to help
  • Marian helped MIT with XRootD set up to support HTTPS; hopefully successful; were able to upgrade 3 of 6 data server but they have a mix of OSG 3.3 and 3.4
  • OASIS Replica production update ran into issues due to Kernel problems so downtime lasted longer than expected. Should be up and running now.

    • xrootd-scitokens - release
    • x509-scitokens-issuer - contrib
  • StashCache documentation overhaul!!!
  • StashCache packaging is also being modified to include auth, and less copy-paste!
  • We will start sending CMS XRootD traffic to the WLCG file transfer monitoring service (MONIT), in development.

  • (Still ongoing) The repo server is going to move, once again. But there should be no noticable differences. If there is, then we failed.


Last Week

  • FIXED: Discussions with with Internet2 to place StashCache in connection points. Waiting on GeoIP issues to be worked out. Should be FIXED with new update!
