  1. AF operation news: CAF24 June 2010 Martin Vala, Arsen Hayrapetyan

  2. CAF operation • Stable during last 2 weeks • root v5-26-00b-6 • AliRoot v4-18-Rev-22 • AliRoot AN v4-19-17-AN (issues since yesterday,covered later in this presentation)

  3. Issues • Online reconstruction: making output files visible to xrootd redirector, RW access for xrduser, DIR_LOCK (bug #68271) ? • Versions v4-19-16-AN and v4-19-17-AN of AliRoot AN won’t load on some workers since yesterday • Staging: files remain in the queue and the download is retried (no limit on retry count) thus impeding the staging of new datasets.

  4. TODOs • Fixing issues • Make “repairing staged data sets” (datasets which are not staged completely and have some of the files marked “CORRUPTED” or “UNSTAGED”) more automatic with cron • Fixing other bugs (package update, data staging, xrddm, etc.) • Determining the optimal memory consumption limit or analysis tasks
