Discussion¶
-
Ongoing storage ticket with Brown; currently it's not OSG-related troubleshooting, so it would be better served if it's tracked by CMS coordinators.
-
Carl working on moving building container to GitHub actions; this enables us to make updates to the
software-baseimage and have them trigger builds for all descendent images. -
Edgar will be working on DOMA tasks so will not have time for software work. BrianL and Marian are interested in seeing XCache-related documentation that Edgar writes.
-
Edgar has been running an XRootD 5 cache in Sunnyvale. No problems so far but there have been auth issues reported against XRootD 5; BrianL will find the GitHub issue so Edgar can test.
Support Update¶
- Edgar: - #65322 -- CMU is having difficulties with GridFTP and XRootD. - Multi-core pilots at Syracuse not matching; Edgar requests help from HTCondor developers, who request additional logs from Syracuse.

OSG Investigations Team¶
- Outage of personel last week, Marian was available only on Monday last week
- OSG Summer School is ongoing this week.
- XRootD Monitoring Validation is ongoing, and taking significant amount of time (and development / bugfixes)
- CVMFS Singularity Sync is going to start using singularity to create the containers. Working on testing, see github discussion:
- https://github.com/opensciencegrid/cvmfs-singularity-sync/issues/245
- More feedback from interested parties and they seem to be happy. Will provide feedback when Derek is back from vacation.
- XRootD 5 release and built in OSG. Preparing TLS configurations for upstreaming, though bugs in xrootd5 are the current issue (watching xcache mailing list).
- organizing presentation on http://gitbhub.com/xrootd/xrootd-k8s-operator on next xcache meeting, IN2P3 folks involved
- GRACC tape backup broke last week, investigated root cause, turned out to be FNAL issue and fixed by the end of business day on last Friday (operations effort)
