Tuesday 15th May

Tuesday 8th May

  • Updated the instructions in the wiki about supporting GridPP DIRAC Service VOs at Vac sites. This makes use of the multipart vacuum pipes in Vac 3.0, which allow the definitions of multiple VMs to be obtained from a single JSON file: https://www.gridpp.ac.uk/wiki/Vac_configuration_for_GridPP_DIRAC (The same mechanism will work in Vcycle 1.0)

Tuesday 10 Apr

  • Vac 3.0 and Vcycle 1.0 released: see GridPP40 talk for details. In particular, it is now possible to add all the GridPP DIRAC VOs to a Vac or Vcycle site with three lines of configuration.

On-duty - Dashboard ROD rota

Monday 5th March

  • AM->GS. A quiet week last week.

Monday 29th January

  • There were a couple of alarms which showed up on the dashboard, but not on the corresponding nagios.
  • DB got fed up with Imperial failing the job-cancel test for CREAM -- the CE is just busy and returns the cancelled state about 30 s after the test 'fails' -- so she filed a ticket questioning the usefulness of the test: https://ggus.eu/?mode=ticket_info&ticket_id=133004.

Monday 20th November

  • Generally quiet. There are three outstanding tickets: low availability at Birmingham, one at Liverpool which might just have gone green, and out-of-date IGTF CAs at Sheffield.

43 Open UK Tickets this week.

135038 (9/5)
The annual review of the UK's information in the gocdb has rolled around again. As part of this could site admins please check their e-mail, telephone number and CSIRT are correct in their site's gocdb entry. In progress (14/5)

135059 (10/5)
Daniela has submitted a VAC ticket, which she assigned to Andrew. If VAC doesn't have a GGUS Support Unit it probably should get one, right? Assigned (10/5) Update: VAC did have a GGUS SU all along.

Tickets that can be closed(?)
IMPERIAL: 135056
QMUL: 133402
Both these ticket's last updates suggested that the ticket can be closed. Update - Henry would like to keep the IC ticket open a bit longer.

Transfer Error Tickets
RHUL: 134945
OXFORD: 135051
I thought that these tickets are worth mentioning, with the on going conversation and debugging going on in the storage group list.
