ZFS is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris in 2005. During 2005 to 2010, the open source version of ZFS was ported to Linux, macOS, and FreeBSD. After Oracle Corporation acquired Sun in 2009–2010, they terminated the OpenSolaris project and ceased releasing source code. In response, the illumos project forked OpenSolaris, including ZFS, to continue its development as an open source project. In 2013, OpenZFS was founded to coordinate the development of open source ZFS. OpenZFS maintains and manages the core ZFS code, while organizations using ZFS maintain the specific code and validation processes required for ZFS to integrate within their systems. OpenZFS is widely used in Unix-like systems.
