On 4th of June the ZFS-Fuse project has released new stable version of the ZFS filesystem for Linux.

Notable new features in the 0.6.9 version are:

According to several sources, the zfs-fuse is mature and stable enough to trust data to it. ZFS is still the most advanced filesystem available and it still offers more usable features than even upcoming btrfs.

EDIT: The official packages for Lucid Lynx are now available on ZFS-Fuse project site so rest of the article is obsolete.

Because in Ubuntu Lucid repositories the package version is still 0.6.0, I’ve built my own packages and published them in my PPA.

To install zfs-fuse in Ubuntu 0.6.9 add repositories in Terminal:

sudo add-apt-repository ppa:jernej/zfs-fuse

To install just find zfs-fuse package in Synaptic or run in Terminal

apt-get install zfs-fuse

Report for full hands-on experience with ZFS on Ubuntu will have to wait until I get replacement hardware for my NAS server system.
