Agenda

(see box on the other side)

Site reports

KIT: Higher load than usual. LHCb stages a lot of data from tape, which breaks their tape system frequently. PoolManagers (7993) is not assigning all requests to the pools. But if the tape system breaks dcache recovers.

KIT CMS puts its new schema to it's limits. Automatic replication is ongoing. Xavier assumes that after awhile the swing-in process is finished and files are replicated sufficiently to solve the problem.

FERMIlab: Issues with bringing data from Tape System to Disk System. It seems the to be the tape system itself.

FERMIlab: Fermilab is asking for support of the Chimera dump tool to make space and file number information available to a web service.
