There is a great deal of activity around Linux filesystems currently. Of the many ongoing efforts, two receive the most attention: ext4, the extension of ext3 expected to keep that filesystem design going for a few more years, and btrfs, which is seen by many as the long-term filesystem of the future.

But there is another project out there which is moving quickly and is worth a look: Daniel Phillips's Tux3 filesystem.

Daniel Phillips has announced the prototype design of a new linux filesystem . The most interesting thing seems to be a different way of implementing versioning: "Unlike the currently fashionable recursive copy ...

Daniel Phillips noted that his new Tux3 versioning filesystem is now operating like a filesystem, "the last burst of checkins has brought Tux3 to the point where it undeniably acts like a filesystem: one can write files, go away, come back later and read those files by name.

We can see some of the hoped for attractiveness starting to emerge: Tux3 clearly does scale from the very small to the very big at the same time.

"It is about time to take a step back and describe what I have been implementing," began Daniel Phillips, referring to his new Tux3 filesystem.

He provided a simple ASCII diagram that detailed the filesystem's hierarchical structure, describing each of the elements.

About one he noted, "the volume table is a new addition not central to the goals of Tux3, but a nice feature to have given that it comes nearly for free.

The friendly conversation [between Daniel Phillips and Matthew Dillion] offers a very detailed look at the design choices made in each of these file systems.

"The big advantage Hammer has over Tux3 is, it is up and running and released in the Dragonfly distro," began Daniel Phillips, offering a comparison between the two filesystem.

He continued, "the biggest disadvantage is, it runs on BSD, not Linux, and it so heavily implements functionality that is provided by the VFS and block layer in Linux that a port would be far from trivial.

Recently Daniel Phillips announced that he is developing a new file system, Tux3. It plans to be a modern file system on level with ZFS and the currently also still in development Btrfs.

Pedro F. Giffuni happened to catch Daniel Phillips' announcement of a new Linux filesystem, Tux3 , which he compared to Hammer .

"Since everybody seems to be having fun building new filesystems these days, I thought I should join the party, began Daniel Phillips, announcing the Tux3 versioning filesystem.

He continued, "Tux3 is a write anywhere, atomic commit, btree based versioning filesystem. As part of this work, the venerable HTree design used in Ext3 and Lustre is getting a rev to better support NFS and possibly become more efficient." Daniel explained:
