  • Mat and Marco should attend CE hackathon today; frontend admins should consider briefly joining.
  • Marco investigating an incompatibility between a 3.6.5 factory (used at FNAL) and newer frontends.

Support Update

  • Marian:
    • Singularity issues at Utah. Should assign ticket to Mats Rynge and add Mat as a watcher.
    • HTCondor not properly handling CNAMEs in the IGWN central manager. Admins should create an A record for now, but BrianB will ask the HTCondor developers to address the issue.
  • Carl:
    • Waiting for response from LIGO about their accounting issue.
    • No follow-up yet from HTCondor devs for DUNE/TIFR. Carl will examine the schedd log for any clues.
  • Mat:
    • Helping Andrew Melo with an overloaded schedd; HTCondor developers have joined the conversation.
    • Greg Daues at U Illinois hasn't responded regarding minor XRootD security issue they found. Fix expected in XRootD 5.4.0; since it's security-related, it will also go into OSG 3.5-upcoming.

OSG DevOps

New: - Request to inject entire HTCondor job classad into GRACC records. Will require gratia-probe-condor changes. - Elasticsearch is being from 7.10.2 to 7.14.1. Some downtime expected, but only momentarily. No gratia probes or clients should notice.

Ongoing: - Shoveler is working and lightly tested. Collector is 90% done. - Checksums in xrootd-multiuser is 70% done.

Back burner: - (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. - XRootD TCP plugin is ready for packaging. Derek will follow up with software team on who to hand that off to. -
