The OpenZFS Virtual Developer Summit kicked off Tuesday with lots of interesting discussions about open-source work around the ZFS file system.
Kicking off the event was the State of OpenZFS by Matt Ahrens. You can see the slideshow as well as the video recording below. OpenZFS 2.0 continues to do well with FreeBSD support discussed much earlier this year, Zstd compression support, lots of performance improvements, redacted send / receive, Zpool hold , sequential resilvering, persistent L2ARC, etc. OpenZFS 2.0 will be a big release on ZFSOnLinux 0.8 and should be released later this year while currently in release candidate form.
Going forward, the annual OpenZFS releases remain their plan, which would mean OpenZFS 3.0 at the end of 2021. There is still talk for OpenZFS 3.0 of macOS support.
There were also discussions on Tuesday about ZFS caching, persistent L2ARC, ZIL performance improvements, sequential rebuild, dRAID, work on send / receive performance, and more.
Slides for many presentations can be found on this Wiki page. Below is Tuesday’s YouTube feed at the OpenZFS Developer Summit 2020, while today there are a few more discussions underway.
