Just when you thought that zfs was the end in the many filesystems saga, along comes MFS - Moose File System. From the web page:
MFS is a networking, distributed file system. It spreads data over several physical localizations (servers), which are visible to a user as one resource. For standard file operations MFS acts as other Unix-alike file systems. It has hierarchical structure (directory tree), stores file attributes(permissions, last access and modification times) and makes it possible to create special files (block and character devices, pipes and sockets), symbolic links (file names pointing to other files accessible locally, not necessarily on MFS) and hard links (different names of files which refer to the same data on MFS).
higher reliability (data can be stored in several copies on separate computers)
dynamically expanding disk space by attaching new computers/disks
the possibility of storing deleted files for a defined period of time ("trash can" service on a file system level)
the possibility of creating a snapshot of a file, which means a coherent copy of the whole file, even while the file is being written
Works on FreeBSD, Linux and MAC OS X. And probably a lot of other unix-like systems.
