    Present: Maiken, Oxana, Balazs (notes), Anders, Ievgen, Lars

     

    i) News

    • Maiken worked on bringing the test cluster back to live again.
    • Mattias: nothing special
    • Ievgen: looking at testing the data improvements (on LUMI box)
    • Anders: more or less the same situation, slowly bringing the services back in Copenhagen, Nordugrid CA crl is back already.
    • Oxana: Bologna WLCG workshop main topic data challenge. 
    • Lars: busy with other project, reviewing Gasper's changes. Had a look at the S3 implementation and got sceptical about its current status.
    • Balazs: reported on the problem with obtaining open sourse status on gitlab.com

     

     

    ii) Topics from the week:

    • SLURM version 26.05 breaks compatibility: on ARC-CE side it is site-admin responsibility, nothing to do in ARC code, optionally make documentation more explicit.
    • Token landscape updates:  we can't assume the token signing keys are not changing, currently such a change requires A-REX restart. Some ticket exists on this topic. Review status of transfer token scopes. 
    • Handling of REGEXP in tokens:  open an issue, current implementation is not nice.
    • arcmon: interesting community contribution but we consider it as a third party service that make use of internal ARC data structures (such as controldir or accounting database)

     

    iii) Bugs: 

    • download nordugrid is down (see above, related to Copenhagen status)
    • github.com issues will be moved over to the new issue tracker (on gitlab): https://github.com/nordugrid/arc/issues

     

    iv) Release:

    - Maiken opened the issue for the 7.3 release preparation
