Hi folks,
I'm looking for an replicated and offline capable network filesystem
which can work behind hi latency links. The only usable one I could
find is Coda, but it doesn't exactly suit my needs, some of the
drawbacks are:
* completely own security scheme (AFS style, not Unix)
* own storage, cannot export existing filesystems
* can only transfer complete files
* doesnt work well behind hi latency links (>80ms).
* not very stable
So I'm thinking about designing a new one, based on 9p :)
The idea is:
* Client side (mounting) is done via normal 9p
* Extended 9p protocol between the primary server and local cache
* Local cache stores its stuff within a local filesystem or
an database
* Files can be watched for update notification
* Batched transfers in background to prevent unnecessary blocking
Does anyone like to join me ?

To: weigelt, 9fans
could you lay out a specific scenario where one would use
your proposed filesystem?

presotto responded to a question about this a while back. might want
to read about cfs, kfs and aan. i'm not sure what you mean by
"extended 9p"; we like 9p the way it is :)

I´m not sure if the version I copied to sources had it. But ofs/oxport
(for inferno)
can be used to dial a remote inferno across very bad latency links.
It knows how to maintain a local persistent cache in a local file system. Cached
files maintain the directory structure.
However, it does nothing regarding replication/disconnected operation.
I´ll copy tomorrow a fresh copy of sources to /n/sources/contrib/nemo/octopus
