Site reports
Lancaster: Had a bad time of it due to getting too full - a lot of slow ops. This caused xroot load and service drops there. Tightened atlas belt a bit helped free up some space, and we’re rolling out meatier MDSs (double the RAM).
Glasgow: Sam build newer versions of xrootd on CC7 and 8. (anticipating 5.6.9), and awaiting any updates for LB.
Action items
@James Walder to schedule a ‘hackathon’ within a F2F to have a session on architectural planning.
@James Walder to prepare an outline of the expected roadmap for XRootD developments in 2024.
