"They have lawyers who say it's fine," he said, adding that Torvalds a few years ago also said as much. Ahrens points to Ubuntu Linux, which ships with an OpenZFS module. dRAID or distributed RAID is a new vdev type that complements existing ZFS data protection capabilities for very large storage arrays. "At the end of the day, it was people getting bent out of shape by a confusing non-issue," he said.Īhrens said that there are still some who worry that the Common Development and Distribution License (CDDL) governing OpenZFS and the General Public License (GPLv2) governing the Linux kernel are incompatible.īut OpenZFS insists the licensing is fine as long as ZFS isn't shipped in the Linux kernel binary. Isaac Huang’s talk at the OpenZFS 2017 developers summit witnessed the expansion of the ZFS storage endurance envelope for large installations. But Torvalds didn't mean OpenZFS, he insisted.Īhrens acknowledged there has been some contention over OpenZFS interface compatibility, but those technical issues have been dealt with. Torvalds, he said, is rightfully suspicious of closed source extensions to Linux and of Oracle. "We're in uncharted territory maintaining cross-OS kernel code in one code base."Īhrens told The Register in a phone interview that Torvald's dismissal of ZFS stemmed from a situation that didn't actually exist, a proprietary version of ZFS used in conjunction with Linux. "In terms of big features, ZFS may be the only cross-platform OS-level kernel code that works on multiple kernels," he said. The FreeBSD developers saw where the innovation was happening, Ahrens explained, and figured it would be better to get OpenZFS code from ZFS on Linux rather than Illumos to remain more current. The initial design only supported configurations where the group size divided evenly into the number of data drives in the config. It breaks the number of drives in the configuration into raidz groups and randomly distributes the data blocks across all available drives. According to Ahrens, most of the major new features in ZFS over the past five years have been developed with ZFS on Linux in mind, rather than the Illumos project, formed to develop OpenSolaris and ZFS prior to the establishment of the OpenZFS project. The dRAID data layout is layered on top of the raidz infrastructure in ZFS.

The merger of OpenZFS into FreeBSD reflects a shift in where ZFS work is being done. Since the release of OpenZFS 0.8, TRIM support was added. ZFS co-creator boots 'slave' out of OpenZFS codebase, says 'casual use' of term is 'unnecessary reference to a painful experience' READ MOREĪhrens said OpenZFS 2.0, expected to ship around the end of the year, will support Linux and FreeBSD, and project contributors continue to improve support for other platforms, like macOS, in the OpenZFS repo.
