RAL Tier1 Operations Report for 23rd October 2018

Review of Issues during the week 15th October 2018 to the 23rd October 2018.
  • The batch-farm is currently (23/10/18), running at reduced capacity (~20%) to facilitate critical kernel patching and/or rebooting of WN's. This should hopefully be completed by midday.
  • No other major issues of note to report for this week.
Current operational status and issues
  • Advance notification of downtime for 25% of our acr-ce's. We will be draining and migrating to new virtualized platform.

    • Update systems to use SL7 and configured by Quattor/Aquilon. (Tape servers done)
  • Internal
    • DNS servers will be rolled out within the Tier1 network.
