From the tahoe-dev Mailing List

Tahoe as a Backend Driver for iRODS

Jimmy Tang submitted the idea of using tahoe as a backend driver for iRODS. iRODS is a data grid software system developed by the Data Intensive Cyber Environments research group (developers of the SRB, the Storage Resource Broker), and collaborators. The list discussed Jimmy's previous work with Tahoe-LAFS and git-annex, paying attention particularly to potential performance bottlenecks. The prevailing hope is Jimmy will attempt the project to determine if the potential bottlenecks are real.

Tahoe Provisioning Tool

Jimmy Tang also submitted a patch for the tahoe provisioning tool. The patch would update the provisioning tool to be more current with disk and user data sizes. Brian Warner brian contemplated removing the tool from the Tahoe executable and making it a standalone program. When Brian makes this change, he will implement Jimmy's patch. An example of Brian's work on this may be seen here.
