        Just wanted to check with you if I can go ahead and delete all the old disk-only, empty, dirs (/castor/ads.rl.ac.uk/prod/atlas/stripInput/ etc ) on CASTOR?

        RAL stage-out timeouts:
            * Rucio clients 1.21.9 should be deployed ~ now
            * to follow-up on effectiveness of the 'fix' :
         Still seeing jobs with same timeout errors, with the new Rucio version. With a few more statistics will pass back to ATLAS Rucio and DDM experts.
         

        Stage-in problems:
          * Useful discussions yesterday; no 'smoking gun'.
          * Aim to correlate between ATLAS reporting and Echo logs.
