Monday 6th March
- There was an ops coordination meeting on Thursday 2nd March - agenda | Minutes.
- The overview talks were: Mid-SLAs | Machine Job Features.
- The main summary items:
- Lessons learned from ATLAS tape usage tests. Follow up via FTS steering group. Will share experience with other experiments.
- "Mid SLA" resources. During the next months accumulate experience at CERN (providing such resources) and in experiments (using such resources). Review accumulated experience after a couple of months and decide what we need to do in terms of tagging, accounting, etc...
- MJF deployment is not as successful as desired. Find help (at least temporary) for deployment campaign concentrating on the LHCb sites. See whether this task would become more important considering outcome of the benchmarking discussion.
- In order to avoid inconsistencies in the naming of the service types along the WLCG IS chain (GocDB, OIM, SAM, experiment-specific systems like Dirac), there will be agreement between representatives from OSG, EGI and GocDB team and IS evolution task force on the policy for introducing of the new service types.
- The next WLCG ops coordination meeting will be on 6th April.
Monday 27th February
- The next WLCG Operations Coordination meeting will be Thursday this week starting at 15:30 CET.
- Themes:
- SLAs and usage of different kinds of computing resources
- Machine/Job Features update
- Experiments, T0, WGs & TFs are requested to add reports to the minutes page at least 1 HOUR before the meeting.
- Tier-1 and Tier-2 sites are asked to please contact wlcg-ops-coord-chairpeople@cern.ch to have a specific slot added in the agenda if you have non-trivial feedback or announcements to be made.
Tuesday 21st February
- Next meeting is on 2nd March.

Monday 20th March 2017, 14.30 GMT
25 Open UK Tickets this week.
But first, a ticket from the UK
127224 (20/3)
Thanks to Daniela for filing a ticket about the ARC monitoring weirdness seen across sites the last few months. Let's hope the monitoring team can get to the bottom of this.
NGI
126808 (24/2)
The "WMS usage" ticket - Daniela notes that after some disheartening closure of the WMS tickets due to lack of support withdrawal of the service might need to happens sooner rather then later. There is an attempt to reassure us that security bugs would be fixed in spite of the lack of dev effort. In Progress (20/3)
Not ECDF
127223 (20/3)
Daniela's quest to sort the dashboard continues with this request to get someone to look at anomalous alarms at ECDF. Sadly the TPM routed it back to the UK. I've tried to bounce it back. Assigned (20/3) In fairness this tickets was re-routed and completed before I finished writing this up.
TIER 1 IPv6
127185 (17/3)
Of interest - a ticket from WLCG requesting that the Tier 1 completes a survey about it's IPv6 readiness and plans. In Progress (17/3)
OXFORD
126928 (3/3)
Are the transfer failures that prompted this atlas ticket still plaguing the site after Kashif's fix last week? Looking at the DDM plots myself I don't think they are, so it looks like this ticket can be closed. In progress (15/3)
And finally, SUSSEX and BRISTOL have a few tickets that could do with an update Although the two Bristol tickets are only a few weeks out of date and I have not followed through with providing support and encouragement to Sussex, so my bad there.
