OpenZFS Developer Summit 2013

Delphix is hosting a developer-focused event for OpenZFS. The goal of the event is to foster cross-platform community discussions of OpenZFS work, and to make progress on some of the projects proposed for this community.

We were previously calling this event "OpenZFS Day", but decided to rename it to reflect its target audience of ZFS developers.

Huge THANK YOU to our generous sponsors

     
     
     
 

The high-level agenda is:

Monday, Nov 18, 9am
  • Talks
  • Breakout sessions
  • Hackathon planning
  • Beer bash
Tuesday, Nov 19, 9:30am Hackathon (hopefully start work on some of the Projects the community has suggested)

Location

The event will be in the Delphix office in San Francisco:

604 Mission St. Suite 400, San Francisco, CA 94105

Speaker Info

Note: If you are in the room, you are potentially a speaker. This will be done in unconference style, so every attendee should come prepared to present or otherwise lead a discussion or session of up to 45 minutes. You can indicate potential topics in the registration table below.

Equipment available:

  • Projector
  • Whiteboard

Hackathon

The goals of the hackathon are:

  • to get people working with ZFS engineers from outside their normal circles
  • to start work on some of the projects we'd like to accomplish

Therefore, we should plan to work in small teams of 2-3 engineers. The team members could be pair-programming, splitting up the work into discrete tasks for each person, or advising / implementing.

Hackathon ideas

Add your idea and your name below. Be prepared to explain your idea at the beginning of the hackathon and enlist/entice others to help with it.

  • Userland ioctls: support for send/recv (fd operations over the wire) User:mahrens
  • larger (1MB) blocksize: shouldn't be too hard if we ignore performance impact User:mahrens
  • dedicated kmem_cache for dedup table entries
  • stdin / stdout buffer to improve performance of zfs send and receive
  • ZFS mechanism to override devices' reported sector size (512 vs 4k) (alex @ delphix)
  • feature flags enhancements for send streams User:csiden
  • set owner of all files within a filesystem with a ZFS property User:csiden

Registration

We are expecting everyone will be there to contribute/participate.

The sign up deadline has passed. A few spots are available for late registration. Mail admin@open-zfs.org if you would like to attend.
