firstname.lastname@example.org Weekly OSG, EGEE, WLCG infrastructure coordination meeting.
We discuss the weekly running of the production grid infrastructure based on weekly reports from the attendees. The reported issues are discussed, assigned to the relevant teams, followed up and escalated when needed. The meeting is also the forum for the sites to get a summary of the weekly WLCG activities and plans

Status: CRUZET-3 is over, it was a good experience, and cosmic runs are more and more mature exercises in terms of CMS computing in the Tier-0 data handling sector. CERN services in CRUZET-3 mostly OK. Plans: extend and finalize tests, and prepare to next cosmic exercise, foreseen for the 2nd half of August.
Status: Work finalized on the P5->CERN transfer system, a repacker replay is now running (since July 17th), namely redoing the repack for CRUZET-3 data. Plans: Next monday CMS will start more replays with some T0 real prompt reco testing.
Status: CRUZET-3 AlcaReco exercises at T1 sites were the first time CMS ran on *data* outside CERN/FNAL. Plans: CMS foresees transfers of the order of few TBs per T1 site from CERN, starting imminently. IN2P3 is custodial for CRUZET-3 (as CNAF was custodial for CRUZET-2).
Plans: CMS would expect a centrally-trigger *big* transfer load of many CSA07 MC datasets to CMS T2's, as a needed step in order to complete the migration of the user analysis to T2 sites. Each T2 should expect to be asked to host a fraction of ~30 TB of those datasets. Good news is that among the needed ones, many datasets are _already now_ hosted by at least one Tier2, so the load may be less than what could in principle be expected. Work is being done to maximize the availability of datasets at T2's with the minimal amount of WAN traffic triggered. Subscriptions to T2's and transfers themselves will start soon, not unprobably it may happen this week already, so please T2 sites be prepared. Once finalized, the usage of T1 for analysis will start to be banned (i.e. once verified dataset can be accessed at 1++ T2 sites, the datasets will be masked in DBS at T1 sites, so CRAB jobs will hence not be able to reach T1 sites anymore).
- Running data consistency campaigns and monitoring campaign (since some weeks)
- more T2/T3's are coming in and joining CMS, and soon the PhEDEx topology
