Week of 060814

Open Actions from last week: Harry to organise conference phone

Chair: Harry

Gmod: Judit Novak

Smod: Thorsten


Log: Nothing

New Actions: Understand why no gridview data overnight when lemon shows export continuing. Also the site distribution seems strange - Budapest, Nicpb and Citcms.




New Actions:

Discussion: gridview team reported that the Gridview archiver died and could not restart as it could not delete the old PID file. Also they use the GOCDB sites database. Nicpb is in Estonia and Citcms in Caltech. Both are CMS sites. CMS report they are starting the transfer back to CERN of 30 TB of MC events and ask us to keep the *-CERN FTS channel going.




Discussion: Many no contact alarms. Database services affected.



Actions: Create new FTS channels for top CMS T2 sites (list coming from M.Ernst). Tune gridftp for transfers to CERN from an Italian (Bari ?) CMS T2 site and compare with untuned site.

Discussion: No contact alarms were due to primary DNS failure (but machine still pingable). There is now a fix for vomrs which sees the Oracle 10gR2 cursor bug. Will try to look for corruption before restarting service. M.Ernst reported problems with T2 MC FTS file transfers to CERN. Individual failures clog up the *-CERN channel and they also see frequent poor gridftp performance on individual transfers. See actions.
