Meeting Goal
Develop an initial strategy for development and releases of L-Store software. There was also some discussion of planned hardware deployment for the near term.
L-Store Releases and Features
L-Store Release 0.8 --- December 4 REDDnet@I2 meeting
- API documentation will be provided
- L-Store Commands Implemented:
- mkdir
- ls
- write
- read
- help?
- Demonstration similar to SC06 will be made at REDDnet@I2 meeting.
- Clients will be made available for installation to 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 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
- StorCor/WebDav 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
L-Store Release 0.9 --- End of January 2007
- Physical delete command will be implemented
- Remaining SC06 bugs will be fixed, plus any new ones discovered
- The meta-data server will be set up on a mirrored-raid device for fault tolerance
- Full L-Store/StorCor interoperability will be implemented
- Server/Depot software will be made available, but only to users willing to work closely with ACCRE staff supervision.
- Full scale testing of ADIC replacement for Proteomics will begin
L-Store Release 1.0 --- May/June 2007
- User Manual and Server Manual will be made available
- Actual release date will be re-evaluated in January of 2007
- Fault tolerance
- recover from lost metadata (I am not sure what mechanism will be?)
- If a depot dies, file metadata will be automatically reconstituted for those files where possible and unrecoverable files will be deleted from the system.
- Switch Proteomics over to L-Store, replace ADIC system.
- Real Server and Depot installer
- Authentication and Security features enabled
- need to spell out more specifically what
- Load balancing on the meta-data servers will be implemented
- Monitoring system: an initial version from Hunters group will be integrated
IBP Development???
- Hunter will have two interns from Sun, he will have them work on the IBP software, convering it to Java.
- Larry has requested input on what is done
- will provide a lot more depot monitoring
Near-Term Hardware Deployment
- Validation, Verification, and Performance Testing Depot
- We will deploy 20 of the Capricorn Depots in a single system that can be used for validation, verification, and performance testing.
- This system will be for developers use only, and it can be taken down at any time. Software can be updated at any time.
- Nightly, the L-Store development release code will be built, installed, and tested with Clyde. This may take a few months to get going smoothly.
- User System
- The remainder of the systems (20) will be deployed as a user facility.
