Tuesday 4th April
- The next ops coordination meeting is this Thursday 6th April. Agenda. The theme is HTCondor accounting work at PIC.
- Any T1 or T2 issues to be discussed?
Monday 20th March
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.

Tuesday 25th April
A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here
- There have been problems with the LHCb Castor instance since the SRM upgrade on the 23rd March. The SRM change was reverted on the 12th April (shortly before Easter weekend). One bug has been identified that is fixed in Castor 2.1.16. Work is now underway to test this Castor version with the aim of moving too it as soon as possible.
- On the 19th April, Atlas reached a milestone of having 1PB of data in ECHO
- The number of batch jobs running in SL6 containers on worker nodes running SL7 is being ramped up.
- The IPv6 addressing scheme for the tier1 has been agreed and is in place. We hope to start offering services via IPv6 in the near future. The Perfsonar nodes on our production network are already running using IPv6.
