[tahoe-dev] A simple 2 nodes replication

[thierry dijoux]

I was wrong for the file name, but when a node is down and you upload a
file, the content of dir (this is an example)
in .tahoe/storage/shares/de/derbnumtsxwu7rhydpxtxizd5y/ is 0 and 1. when
all nodes are up, there is 0 in a node and 1 in the other.
I don't know if it will help or if tahoe-lafs is not designed to do
replication on only 2 nodes.
