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

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?
