Here’s a great blog about ZFS and Apple from Adam Leventhal, who worked on it: ZFS: Apple’s New Filesystem That Wasn’tīy then, Sun was hitting hard times and Oracle swooped in to purchase the company.

And this appears to have been concerning enough to Apple that they dropped ZFS support from Mac OS X 10.6 “Snow Leopard” just before it was released.

Although ZFS definitely did not copy code from NetApp, the copy-on-write approach to snapshots was similar to WAFL, and those of us in the industry grew concerned that the NetApp suit could impact the future availability of open-source ZFS. Sun counter-sued later that year, and the legal issues dragged on.

The skies first darkened in 2007, as NetApp sued Sun, claiming that their WAFL patents were infringed by ZFS.

The darling of the industry, ZFS quickly appeared on Linux and FreeBSD and Apple even began work to incorporate it as the next-generation filesystem for Mac OS X!

And Sun open-sourced most of ZFS, allowing it to be ported to other operating systems. When ZFS appeared, it was a revolution compared to older volume managers and filesystems.

Data can be compressed on the fly and deduplication is supported as well.

ZFS includes robust snapshot and mirror capabilities, including the ability to update the data on other volumes incrementally.

Mirroring and multiple-parity “RAID Z” are built in, combining multiple physical media devices seamlessly into a logical volume.

When ZFS detects an error, it can automatically reconstruct data from mirrors, parity, or alternate locations.

ZFS includes checksumming of all data and metadata to detect corruption, an absolutely essential feature for long-term large-scale storage.

ZFS achieves the kind of scalability every modern filesystem should have, with few limits in terms of data or metadata count and volume or file size.

The ZFS engineers did a lot right when they combined the best features of a volume manager with a “zettabyte-scale” filesystem in Solaris 10: When ZFS first appeared in 2005, it was absolutely with the times, but it’s remained stuck there ever since. I figured this needs some explanation and context, so at the risk of agitating the ZFS fanatics, let’s do it. In my posts on FreeNAS, I emphatically state that “ZFS is the best filesystem”, but if you follow me on social media, it’s clear that I don’t really love it.

But I put all my valuable data on ZFS because it simply offers the best level of data protection in a small office/home office (SOHO) environment. ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice it’s inflexible it lacks modern flash integration and it’s not directly supported by most operating systems.
