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:
{|border="1" cellpadding="10"
|-
|valign="top"|Monday, Nov 18
|
* Talks
* Breakout sessions
* Hackathon planning
* Beer bash
|-
|Tuesday, Nov 19

|}
 
=== 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 [http://www.delphix.com/company/about-delphix/ 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]]
