CRFS introduction
CRFS is a network protocol that lets clients share access to a file system
which is hosted on a server. Its main features include:
- general-purpose "posix" file system semantics
- cache coherency
- aggressive metadata performance
- efficient and flexible snapshots
- robust data integrity protection
The implementation hosted here includes a client module for the Linux kernel
and a UNIX user space server daemon.
Status as of March, 2008
CRFS is in the initial phase of design and implementation. It is not ready
for stable use and should not be trusted to reliably store data.
CRFS is made available at this early a stage so that people can participate
in the design and implementation of the system.
The following major changes will happen in the not too distant future:
- basic file data coherency protocol
- extending coherency protocol to cover metadata
- update to a modern BTRFS disk format
Announcements of major changes in the status of the CRFS project will be
sent to the crfs-announce mailing list.
How to help
The brave can try running the software and will quickly cause it to fail.
Reporting failure on the crfs-devel mailing list will help us understand what
functionality to focus on initially.
If crashing your machine doesn't sound like a fun time, reporting what you
would like CRFS to do well on the crfs-users mailing list would also help us
understand the user base that much better.
Maybe you've always wanted to maintain a
FUSE client for an unstable network
protocol which is undergoing rapid change. Now's your chance!
