[tahoe-dev] 26C3 Tahoe Grid (and strange repair bug)

[Francois Deppierraz]

Hi Folks,

A temporary Tahoe grid has been setup at 26C3, all the information is
available on the wiki if people want to connect to is.

http://events.ccc.de/congress/2009/wiki/Tahoe-LAFS_Grid

I installed a new Tahoe storage node on an small eeepc with a 1.5 TB USB
hard disk.  This storage node is running Ubuntu 9.10 and I installed
Tahoe from the tahoe-lafs package.

A few test files have been uploaded to a public directory.

But when I try to run a deep-check --repair operation on it, it fails
with the following error message.
