Daniel Phillips has announced the prototype design of a new linux filesystem (implementation has only begun). The most interesting thing seems to be a different way of implementing versioning: "Unlike the currently fashionable recursive copy on write designs with one tree root per version, Tux3 stores all its versioning information in the leaves of btrees using the versioned pointer algorithm. This method promises a significant shrinkage of metadata for heavily versioned filesystems as compared to ZFS and Btrfs".

As ZFS cannot be ported (CDL is not compatible with GPL: http://kerneltrap.org/Linux/Proposing_Read-Only_ZFS) to Linux without using the additional abstraction layer FUSE and Tux3 have a long development way to go, until it will become suitable for a production environment, I would like to know, whether it is possible to port the HAMMER fs to Linux.
