Operations News

  • CASTOR stress testing started of V/SL10 disk servers and is progressing well. We've decided to introduce these disk servers with 4x the 'old' slot count (apart from GridFTP) The SL08s are being phased back in with 2x the 'old' slot count.
  • First version of new Ganglia based castormon now available

Operations Problems

  • More problems on Gen SRM which were load related, by a T2K user. The Maui fairshare will be reduced.
  • castor151 (LHCb Stager) spontaneously rebooted. Castor headnodes were unaffected, but a number of LHCb tapes got a disabled state. The VMGR scheama will be moved onto another node.
  • Approx. 25% of transfers using the RAL FTS are failing for unknown reasons. Doesn't appear to be CASTOR related.
