8. 19th September 2003Tim Adye8 Recent Changes (cont) Batch worker nodes upgraded to RedHat 7.3 Will simplify merging BaBar tier1a with UK tier1 farms should allow us to “borrow” spare capacity Front-ends remain RedHat 7.2 analysis-13b ( 10.4.4 ) and analysis-14 ( a ) ( 12.5.2 ) compiled in RH72, but jobs validated to run on RH73 as well Last RedHat 6 box switched off on Tuesday “Safer” Kanga conditions updating procedure (Chris) Linux Objectivity server installed and running SP (Wahid) Objy Conditions for series-12 (TimB)

9. 19th September 2003Tim Adye9 Other Planned Changes Finally bring old Sun disk server back into service Reconfigured and extensively tested since catastrophic file-system problems in February Will provide 4.2 TB of sorely needed space Try to keep older data there to minimise risk/load CVS hack to allow checkouts ( addpkg ) without AFS token May require a minor change at other sites that use RAL CVS – Manny will post details soon Move user staging disk ( /stage/babar-user1 aka $BFROOT/work ) to larger and faster disk (Manny) 0.8 TB  1.4 TB

10. 19th September 2003Tim Adye10 Kanga Data at RAL All available disk is now full 4 TB more on the Sun in next day or two, but that will be quickly filled Need space for run 3 and series-12 reprocessing SP signal and generic conversion going well Real data conversion has to be restarted AllEvents and 15 streams for data and generic MC Need space for New Kanga (CM2) staging area Most will be kept in the Datastore (tape) and staged in automatically Need to remove unused data “Bad” series-12 real data Series-10 old tag ( <=K10.4.1b ) Anything else?
