WLCG Operations Coordination - AgendasWiki Page

Monday 16th April

  • There was a meeting on 12th. Agenda | Minutes.
    • Balazs Konya is new in the role of WLCG Middleware Officer.
    • Next meeting 7th June.
    • Delay for submission of GGUS tickets for recalculation should be respected. It is 10 days after monthly drafts of the availability reports are sent around by WLCG project office. If the GGUS tickets are not submitted respecting 10 days delay, they are not accepted.
    • A/R recalculations will be accepted if they are relevant to the site MoU commitment or concern time ranges of sufficient length.

Monday 5th March

  • The agenda and minutes from the WLCG ops coordination meeting last week are available.
  • Special topics were: CNAF recovery update; SAM recalculation policy draft discussion and Progress on WLCG Storage Space Accounting Prototype including tape metrics.

Tuesday 27th February


Tier-1 - Status Page

Tuesday 1st May Report for the Experiments Liaison Meeting (30th April 2018) is here.

  • The proposed emergency chassis intervention was brought forward (23/5/18 - 13:00), when the chassis began to intermittently reboot itself. This intervention was completed successfully and without further incident.
  • The scheduled firewall replacement (25/4/18), appeared to be completed successfully. However, during the afternoon the connection between the Tier1 network and the RAL core was failing intermittently. The problem seemed to get worse as the afternoon progressed. Due to disruptions to connectivity both on and off site, caused (we think), by running on the new secondary firewall, we flipped the Master-Slave router pair so that the Master was running on the standby side. The change occurred at approximately 17:00 on the Wednesday and normal service was subsequently restored. There is currently an ongoing investigation as to why the firewalls did not fail-over correctly. There is an "at risk" scheduled outage for the 2nd May 2018 when Networking/DS will be performing another firewall switch-over to ensure that this issue has been resolved.
  • Our primary OPN link went down on Tuesday morning (24/4/18), OPN two and three stayed up. This was resolved by Wednesday (25/4/18), around 15:00. JANET appear to have fixed this issue by the age old SysAdmin trick of "switching it off and then back on again".

  • 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.
