We just discovered Tahoe and are curious to try it for our internal use, for a
cheap, easy to install, and redundant distributed archive system.
1/ Is it possible to specify that we have N servers and want tolerance to K
failure ? Or to know the state of redundancy ?
2/ http://lwn.net/Articles/280483/ explains that files are locally encrypted
with AES, then splited with some kind of error correction algorithm. Is it
possible to not encrypt, and only use the Tahoe as a redundant distributed
3/ Did someone benchmark the performance on a LAN ? with CLI and/or fuse ?
4/ About fuse modules, found in contrib/
impl_a and impl_b said that only read is suportted
but http://allmydata.org/~warner/pycon-tahoe.html says FUSE plugin:
"allowing them to read and write arbitrary files."
We would be very happy if read and write work under linux :-) (we don't use
atime, nor do tricky things on our filesystems)
5/ Does it scale to TB filesystems ?
Ideally we would like a ~15+ nodes with 500 GB each, and tolerance of 3~4
Congrats for this very impressive job. Best regards.
