OpenZFS Dev Summit 2022

The tenth annual OpenZFS Developer Summit was held in person, Oct 24-25 (Mon-Tue) in San Francisco.

As with previous years: The goal of the event is to foster cross-community discussions of OpenZFS work and to make progress on some of the projects we have proposed. The first day of the conference will be held at the Childrens' Creativity Museum, and consist of presentations, followed by a reception. The second day of the conference will be held at a nearby office, and consist of a few presentations, and the bulk of the day will be spent on a hackathon, where you'll have a chance to work with other OpenZFS developers to improve the project.

In order to make the OpenZFS Dev Summit as safe as possible for the more vulnerable members of our community, we required (and provided) masks and negative COVID tests during the event.
