      • WLCG Ops: EGI GOCDB downtime for TAPE service
        • SRM.nearline no longer makes sense for WebDAV endpoints with TAPE REST
        • we need new GOCDB "Service Type"
      •

      • dCache: removing internal dependencies on SRM space manager -> transition to dCache quotas
      • reminders about existing (HTTP-TPC) related issues
        • dCache: HTTP-TPC performance markers and RemoteConnections dCache#7441
          • different performance markers types? (start, connection established, connection closed, finish, ...)
        • StoRM: no support for RemoteConnections in performance markers (ticket?)

      Speakers: Petr Vokac (Czech Technical University in Prague (CZ)), Francesco Giacomini (INFN CNAF)

      Alma9 xrd client & sites with Root CA signed by SHA1

      • Is it a mistake that XRootD client verify signature of self-signed Root CA?
      • Alma9 (lxplus) issue with certificates where IGTF Root CA use self-signed with SHA1
        • only problems with xroot protocol
        • create XRootD issue issue#2150

      Rucio + FTS with tokens

      • details in the "Rucio Token Support" persentation last week in WLCG DOMA General
      • FTS implemented configurable token issuer -> VO mapping (FTS-1987)
        • Rucio can't easily use tokens & X.509 to query FTS for transfers submitted with tokens vs. X.509
          • Now Rucio can get all VO transfers independently on authorization with FTS
        • Require special FTS branch / build
          • deployed on CERN FTS pilot
            • most probably it'll be deployed also on ATLAS and CMS instance for DC24
          • to be clarified participation of non-CERN FTS servers

      StoRM stat with tokens

      • support for "stat" with storage.create and storage.modify STOR-1600
