OSG Software Team¶
- Doc focus this Thursday Oct 29 1:30pm
- Kubernetes hackathon tomorrow Oct 27 1:00pm
- CVMFS + EL6 nightly failures due to SELinux issue and newly changed OSG CVMFS config; workaround in place
- Tech team priorities this week: https://opensciencegrid.atlassian.net/secure/RapidBoard.jspa?rapidView=19&quickFilter=66
Discussion¶
- Our VIRGO contact is the VIRGO Computing Coordinator Stefano Bagnasco ([email protected]).
- IRIS-HEP Analysis Systems workshop today and tomorrow.
- AI (Diego): diagnose XRootD 5 on EL8 issues.
- AI (Edgar):
- debug why xrootd-multiuser plugin keeps XRootD server from starting.
- debug why binary used to generate macaroons is core dumping; contact Zach Miller for assistance.
-
AI (Mat): help Mark Coatsworth with EL8/Python3 support for HTCondor-CE.
-
Multiple issues with BOSCO/Hosted-CEs:
- Job persistence hasn't been implemented for Hosted-CE containers yet, which means restarts kill jobs. This makes testing and config updates somewhat harmful. A potential solution is using a PersistendVolumeClaim but that's not easy on SLATE.
- Bosco keeps persistent state in
/tmp; Expanse had their submit node set up with DNS round-robin which means state was sometimes there, sometimes not. Edgar added a manual workaround.
Support Update¶
- Expanse (Edgar, BrianL): CMS user not being set up properly and PATH being overriden: PRs in to fix both
- JLab (Edgar): Figured out origin port re-use issue: problem with the site config
OSG Investigations Team¶
- Elasticsearch on Kubernetes!
- OASIS upgrade last week (supports SSH logins via authorized keys registered in COmanage!).
- OSG GRACC upgrade coming this week, v7.8.2 -> v7.9.2.
