        VO Liaison CMS 1m
        Speaker: Katy Ellis (Science and Technology Facilities Council STFC (GB))

        Not much to report. We had 2 bank holidays for Easter - no major problems observed.

        From last week:

        Open access test - showed that CMS (and other VO) files are available to be recalled from Antares buffer by anyone, even without a cert proxy. Being addressed: https://stfc.atlassian.net/jira/servicedesk/projects/STAH/queues/custom/263/STAH-19

        --No update. 

        Otherwise, plenty of things to be done, but several people on leave/off sick. 

        Need to talk to George about test files being written to Antares and make sure they never go to tape.

        • Tickets
          • vector read
            • Code review is ongoing, larger scale test is planned
          • Request to remove env variable
            • LHCb jobs also need the variable
            • It seems like its removal do not solve the original problem (warning message)
        • Operational issues
          • A lot of failed WG Production jobs last evening, due to vector read problems
          • Corrupted files were found on ECHO last week, reported to LHCb computing team
        • Pledges
          • Is it OK to extend LHCb disk storage according to pledges?
