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.

The high-level agenda is:

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

Location

The event will be in the San Francisco Bay Area, most likely in San Francisco. The specific location will depend on how many people plan to attend. The hope is that we can have it at the Delphix office in San Francisco. If it becomes too big, we'll have to reconsider and find a different location.

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
  • replace dn_ranges/free_range_t with range_tree_t User:mahrens
  • 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

If you plan to attend the event, please edit this page and add yourself below, or contact ann.togasaki@gmail.com. If you would like to present and/or have suggestions for what you would like to learn about, please include those details. We are expecting everyone will be there to contribute/participate. (If you need edit permission for this page, email your login name to admin@open-zfs.org)

The sign up deadline is 11:59pm Pacific Time on Sunday, October 27, 2013. We need to have a cutoff date so that we can plan for a space that is large enough to accommodate everyone who wants to attend.
