L-Store Development and Releases

L-Store Release 0.8 --- December 4 REDDnet@I2 meeting

This release is "released." Documentation and Client software is available here (look under "Downloads").

  • API documentation will be provided
    • with the caveat that it is subject to change
    • may change due to input from REDDnet community
  • L-Store Functionality:
    • mkdir
    • ls
    • upload
    • download
    • command line help
    • storage fault tolerance via weaver erasure codes (upload and recovery)
  • Demonstration similar to SC06 (but on a smaller scale... 20 Gbs?) will be made at REDDnet@I2 meeting.
  • Clients will be made available (from REDDnet website) for installation by attendees at REDDnet@I2
    • for user testing and application development
    • files written to depots should be considered scratch
  • Server and Depot software will not be made available at this point.
  • Bugs: a dozen or so minor (non-data-threatening) bugs were discovered at SC06. As many of these as can be fixed will be, the rest will be fixed by "0.9" release.
  • ACCRE will work with Med Center Staff (Leibler/Proteomics) to begin the process of migrating them over to using L-Store instead of ADIC
  • NevoaExplorer interface (Hunter)
    • This interface will work with existing depots
    • Software will be demo-ed at REDDnet@I2
    • Full integration with L-Store will likely not be complete at this stage
    • Hunter is making a generic layer that will be agnostic to protocol (NFS, CIFS, L-Store)
  • Omissions
    • No Physical Delete
    • No Authentication and Authorization
    • No production depots publically available, but public depots for scratch files and testing will be available.
