Oracle Could Still Make ZFS A First-Class Upstream Linux File-System
Since Oracle acquired Sun Microsystems the dream of having the ZFS
file-system part of the mainline Linux kernel. has looked much more bleak
that they would re-license the ZFS kernel code under a license compatible
with the upstream GPLv2 Linux kernel. But an Oracle engineer presented
today that the ZFS Linux dream might still come true.
The OpenZFS Developer Summit 2017 kicked off today in San Francisco. Mark Maybee of Oracle was today’s keynote address on ZFS now and in the future.
Mark wants to see ZFS become a core part of Linux. He wants it to become “the file-system of Linux” and “that could happen” for “core Linux.” He later said, “it’s a possibility… but I can’t say how strong of a possibility,” that includes talking with Oracle lawyers about the code license of both ZFS and Solaris. Mark would like to see Oracle port Oracle ZFS to Oracle Linux and upstream that. He commented, “Hard to say if it will happen…Oracle is very protective of their IP. We’ve had conversations about it.”
Seeing ZFS become a first-class Linux file-system with upstream support is clearly something Maybee is passionate about, but at this stage isn’t clear if that will actually happen. At least it’s being talked about internally and perhaps stands better chances now with their reduced investment in Solaris. He does acknowledge though things are changing at Oracle while culturally still have challenges with the open-source way and a tough time with the “giving part” of open-source collaboration but not the “taking” part.
Other ZFS improvements he would like to see besides great Linux support is supporting the file-system properly for persistent memory / Intel 3D XPoint memory as well as improved cloud support.
