1	2025 OpenZFS Summit Hackathon and Collaboration Project Ideas
2	Idea	Description	Proposer	Notes	Pres#	Vote Points

3	Add JSON output form to zdb	Add -j/--jason flag to zdb and format output for -dddd	Kristen Webb		1	4	Bonzai!
4	One-ioctl zfs list	Instead of one ioctl per dataset, build the whole tree in a single ioctl to reduce overhead	Paul Dagnelie	Negative results are still results!	2	2
5	Make 'cp' multithreaded	Make copies faster	Tony Hutter		3
6	Embedded Special Class	Allow normal vdevs to have some special metaslabs	Don Brady		4	6	Kingfisher
7	Synchronous Directory xattrs		Daniel P		5	5	Bonzai
8	Write throttling on the number of dirty transactions	Write throttling on the number of dirty transactions	Bryan Maloney		6	2	Typewriter
9	Single line autogen.sh	Step one of build bootstrap improvements	Joseph Holsten		7	6	Wall-E
10	Review/improve failfast	ZFS already sets failfast flag for its I/Os (at least on Linux) to control number of retries. But it could probably do better job, depending on still available redundancy, etc. to reduce effects of misbehaving drives on applicaiton latency.	Alexander Motin		8	1
11	Updating Docs		Alek Pinchuk		9	7	Mini Shuttle
12	Iterators LibZFS core		Andrew Walker		10	4	Statue of Liberty
13	Property Templates		Rob		11
14	Update the Official Projects Page	https://openzfs.org/wiki/Projects	Michael Dexter	Collaboration
15	OpenZFS Native Auditing	What auditing facilities can OpenZFS provide?	Allan Jude	On the schedule, discussed with Michael Dexter
16	Pooled inodes in nested Datasets	Can the conflicting inode issue be resolved?	Michael Dexter	On the schedule, discussed on the Production User Calls
17	illumos OpenZFS Reunion	Provide OpenZFS to illumos as a package? In-base?	Many	On the schedule, discussed on the Production User Calls
18	Improve the OpenZFS Test Suite	See "illumos OpenZFS Reunion"	Many	On the schedule, discussed on the Production User Calls
19	Improve/redefine libzfs	libzfs_core and Channel Programs to do not satisfy consumers	Many	On the schedule, discussed on the Production User Calls
20	"OpenZFS3" S3 bucket dataset type	What would a "bucket" dataset type look like?	Many	On the schedule for collaboration, discussed on the Production User Calls, OpenZFS Basecamp
21	Build Improvements	Document and simplify build (especially test) process for new users.	Joseph Holsten	Ultimately only simplification of autogen.sh
22	Per allocation class space reporting	Pool properties report only one set of free/used space, while it would be good to know how much special or dedup space is available on the pool without looking into individual vdevs.	Alexander Motin
23	Empty vdev removal	Vdev removal has a lot of limitations based ot ashift, topology, etc. But if the vdev is completely empty (for example, never used dedup vdev), the limitations don't matter	Alexander Motin
24	JSON output for zfs diff	Continuing above thought -- add -j flag.	Andrew Walker
25	Pre-Size script for future Large Label	Pre-partion (and properly flag zpool creates) for devices	Stew	Prep now for 2.5x w/o rebuilding
26	ZFS Module Param Namespaces		Don Brady
27	Release and Organizational Policies		Brian Behlendorf, Michael Dexter
