The two projects should be referred to as “Oracle ZFS” and “OpenZFS” to distinguish them as development efforts, but the user still types the ‘zfs’ command, which on FreeBSD relies on the ‘zfs.ko’ kernel module. This means that there are, sadly, two politically and technologically-incompatible branches of “ZFS” but fortunately, OpenZFS is orders of magnitude more popular thanks to its open nature. #Openzfs sharenfs code#Oracle has steadily continued to develop its own proprietary branch of ZFS and Matt Ahrens points out that over 50% of the original OpenSolaris ZFS code has been replaced in OpenZFS with community contributions. ZFS Day has grown into the two-day OpenZFS Developer Summit and is stronger than ever, a testament to the passion and dedication of the OpenZFS community. #Openzfs sharenfs plus#This imbalance plus several successful ZFS Day events led ZFS co-founder Matt Ahrens and a group of ZFS developers to announce the OpenZFS project, which would remain a part of the Illumos code base but would be free to coordinate development efforts and events around their favorite file system. While most if not all users of Illumos and its derivatives are ZFS users, the majority of ZFS users are not Illumos users, thanks significantly in part to FreeNAS which uses the FreeBSD operating system. Disappointed but undeterred, a group of OpenSolaris users and developers forked the last public release of OpenSolaris as the Illumos project. Yes, ZFS is really as good as people say it is.Īfter enjoying nearly a decade of refinement by a growing group of developers around the world, ZFS became the property of database vendor Oracle, which ceased public development of both ZFS and OpenSolaris in 2010. Both commands employ a user-friendly syntax such as ‘zfs create mypool/mydataset’ and I welcome you to watch the appropriately-titled webinar “ Why we love ZFS & you should too” or try a completely-graphical ZFS experience with FreeNAS. On any ZFS platform, administrators use the zpool and zfs utilities to configure and manage their storage devices and file systems respectively. For the first time, ZFS empowered users of any budget with enterprise-class scalability and data integrity and management features like checksumming, compression and snapshotting, and those features remain unrivaled at any price to this day. #Openzfs sharenfs portable#The portable nature and advanced features of ZFS led FreeBSD, Linux, and even Apple developers to start porting ZFS to their operating systems and by 2008, FreeBSD shipped with ZFS in the 7.0 release. ZFS was revolutionary for completely decoupling the file system from specialized storage hardware and even a specific computer platform. #Openzfs sharenfs license#I will do my best to clarify what exactly these two terms refer to.įrom its inception, “ ZFS” has referred to the “Zettabyte File System” developed at Sun Microsystems and published under the CDDL Open Source license in 2005 as part of the OpenSolaris operating system. You’ve probably noticed that this blog and the FreeNAS blog refer to “ZFS” and “OpenZFS” seemingly at random when talking about the amazing file system at the heart of FreeNAS and every storage product that iXsystems sells. I admit that we geeks tend to get caught up in the nuts and bolts of enterprise storage and overlook the more obvious questions that users might have. Our Senior Analyst clears up what ZFS and OpenZFS refer to and how they differ. You’ve probably heard us say a mix of “ZFS” and “OpenZFS” and an explanation is long-overdue.
