ZFS on Linux

This article explores two methods for using ZFS in Linux. The first uses the Filesystem in Userspace (FUSE) system to push the ZFS file system into user space to avoid the licensing issues. The second method is a native port of ZFS for integration into the Linux kernel while avoiding the intellectual property issues.

Introducing ZFS

Calling ZFS a file system is a bit of a misnomer, as it is much more than that in the traditional sense. ZFS combines the concepts of a logical volume manager with a very feature rich and massively scalable file system.
