ZFS is an Open source File System and logical manager designed by Sun Microsystems. ZFS is among the most featureful and extensible Filesystem ZFS which include support for high storage capacities, fast snapshots and copy-on-write clones, integrity checking and automatic repair, etc. All-in-all, this make this File system a Kick-ass solution for the Business and even power home users.
In previous release 10.5, ZFS was available in read-only mode. Before that, Apple released the “ZFS Beta Seed v1.1”, which allowed read-write access and the creation of zpools.
And Today, Apple announced a shutdown of the ZFS project on Mac OS Forge. No explanation was given, just the statement: “The ZFS project has been discontinued. The mailing list and repository will also be removed shortly.” Versions of the previously released source and binaries, as well as the wiki, have been preserved and development has been adopted by a group of enthusiasts.
It’s hinted that this was caused by legal issues surrounding the merger of Sun Microsystems and Oracle, which caused Apple to back away from the next-generation file system technology.
