LFCMeetJuly8

Introduction

  • Meeting of the sub-committee to address LFC migration in the US cloud.
  • Coordinates:
    • Tuesday, July 8, 10am Central/5pm CERN
    • Phone: (605) 475-6000, Access code: 735188; Dial *6 to mute/un-mute.
  • Background: SubCommitteeLFC
  • Attending: Armen, Patrick, Rob, Alexei
  • Apologies: Hiro

Follow-up on Action Items

  • Follow-up with Paul on data mover (Torre)
    • No news for now - lots of other pilot development issues on Paul's plate.
  • Preparation of BNL test site which uses OSG 1.0 wn-client (Xin, John)
    • An updated version of the wn-client is available and needs to be tested.
  • Migration recipe for LRC to LFC conversion (Hiro)
    • Will need to get something documented here when Hiro returns.
  • Setup a Tier2 w/ LFC and Mysql backend to develop experience at the Tier2s
    • UC (Charles) - we've not been able to make much progress due to other pressing problems.
    • UTA-DPCC (Patrick) - in the middle of CPB conversion, no time.

Carryover

  • did not discuss any of these 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.
  • Did not converge on a migration date for the full production LRC at BNL - this depends on results of the BNL test site.

AOB

  • Meet again in two weeks.
