ZFS on Linux?

Markus Thielmann — Wed, 2008-05-21

Apparently Jeff Bonwick (CTO of Sun Storage Technologies and head of the ZFS project) and Linus Torvalds met early in May to discuss "something".

While Bonwick's blog post is quite cryptic and ends with "All I can say for the moment is... stay tuned", he left a few clues:

* The blog entry is titled "Casablanca" (obviously referring to the quote: "I think this is the beginning of a beautiful friendship")
* The entry is filed under "ZFS"
* He talks about peanut butter on chocolate and vice versa

With all these hints, it's quite hard not to think about an integration of ZFS into the Linux kernel. In case you didn't follow the discussion around ZFS: The Zettabyte File System is a 128-bit filesystem developed by Sun and published as open source under the CDDL. It's well known for some superior features like support for high storage capacities, copy-on-write, snapshots and clones. Because of patent issues and license problems ZFS can't be integrated into the Linux kernel. I'm wondering if Sun is planning to change it's license and patent policy regarding ZFS.

I'd love to see Ubuntu Intrepid Ibex+1 booting from a ZFS partition.

If I recall correctly, booting from a ZFS partition is impossible due to how it works (with a tree-like structure for where each part of a file is located). /boot has to be some other filesystem, but / can be ZFS just fine on the Unices that support it.
