LFC deployment at BNL

• Done, in use

LRC content migration status at BNL

• LRC is still in use
• Takes 6 hours to come up to date (currently a month behind)
• Will update next week.

Panda integration testing

• Restarting

LFC client packaging in VDT

• Available this week

LFC at Tier2

• None - but expect to start with VDT-packed LFC this week.

Carryover issues

• Hiro pointed out the problem with supporting root files in the same catalog as the "normal" grid-resident files. These root files are not visible to the grid - do they belong there? Is there a hack that can be made to continue to support (local) cataloging for PROOF farms? Create a separate catalog? We did not converge on a solution for this problem - will need to find a solution. Not a problem.

AOB

• Next meeting: August 27
