Operations News

  • Planning for the 2.1.14 upgrade is complete. NS upgrade and stage 2 (Stagers) all scheduled. However note that we intend to deploy version 2.1.14-13 instead of 2.1.14-11 due to some rebalancing and tape recall issues with the former version.
  • Facilities 2.1.14-11 to 2.1.14-13 on Wednesday 11th June has been postponed.
  • Elastic Search has been through some testing, others encouraged to use it, see Rob for details.
  • A bug in the ATLAS deletion system has been identified that may have contributed to the deletion problems on their CASTOR instance. However, the key test of running the ATLAS deletion scripts locally at RAL has still not been done and awaits Alastair and Shaun being in the same place.
  • We continue to decommission, prep for redeploy and deploy disk servers.
