Tuesday 23rd January

  • There was a WLCG ops coordination meeting on 18th January.

Tuesday 21st November

  • The next WLCG ops coordination meeting will be on 7th December. Do we have any topics we would like covered?

Tuesday 7th November

Tuesday 10th October

  • There was an ops coordination meeting last Thursday 5th October: Agenda | Minutes.
    • There is one action for us to follow-up: "Collect plans from sites to move to EL7". We could make use of the Batch Systems table.


Tier-1 - Status Page

Tuesday 16th January Report from the last Tier1 - Experiments Liaison Meeting at on 10th January is here.

  • Ongoing patching for latest security issues.
  • We had announced the decommissioning of our WMS service. This was brought forward. The WMS service had no jobs in it and would have needed patching. It was set into drain mode so as to stop accepting any new data on Wednesday 10th Jan.
  • Disk server gdss745 (AtlasDataDisk - D1T0) has failed with loss of all data on the server. The problem was triggered by a failed drive. However, errors seen on other disk drives while this one was rebuilding led to loss of the RAID6 array. There were around 960,000 files on the server - around half of which were unique. A post mortem investigation of this incident will be carried out.
Storage & Data Management - Agendas/Minutes

Wed 06 Dec

  • Another success story - CERN@School running machine learning at QMUL
  • Technical events coming up - hepsysman and cloud workshop at Crick. We ought to do something Useful or Interesting.

Wed 15 Nov

  • More xcache progress at some sites; less at others who may be blocking on dependencies or be busy with Other Things(tm)
  • Some interest in following the non-X.509 authentication/authorisation

Wed 08 Nov

  • Not (very) modest at all progress on xcache testing... from Chris at RALPP

Wed 01 Nov

  • (very) modest progress on xcache testing...
  • Except that RALPP has it fully working for dCache - hope to get full report next week
