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.
- Poor mans compressed send (decomp when recv)
- new CLI option to enable send features: zfs send -x embedded,largetblock or -x all
- Sha 512/256
- JSON command output
- File cloning with implicit indirection
- Rip out scrub throttle, queue mb not ios
- print usage message for specific property
- zfs help command
- One man page per subcommand
- Channel Programs - continuation of work from last year's hackathon
- See project page, slides and video describing project
- compile ZFS on Linux with -std=gnu99; does it work?
- storage pool aging
- specify histogram of free segment sizes
- allocator chooses locations to satisfy histogram
- "get next file" syscall
- iterates in object # order, opening next file; zfs prefetches dnodes
- could speed up operations that need to operate on every file in a filesystem, e.g. "chmod -r"
- Porting Party - learn how to contribute changes to a new platform
- Upstream zfs-make - tool to quickly build zfs on illumos
- performance analytics framework - record performance, store & display (dtrace + graphite?)
- USE method data collection framework for performance analysis (http://www.brendangregg.com/USEmethod/use-solaris.html)
- Illumos grub2
- Clean up embedded zil code
- UTF-8 dataset & poolname (Richard)
- vdev kstats (Richard)
- zfs_core collaboration (Richard)
- collectd agents (Richard)
- scrub/resilver progress (Richard)
- promote prefetch reads to sync reads
- object count per user in DMU
- make zfs recv less trusting
- improve arc_kmem_reap()
- raidz1 for single device
- static analysis tools for zfs
- dynamic analysis for ztest
- improved documentation for developing zfs on linux
- runtime lock analyzer
- make dtrace probes in linux to work with lttng
- per zone I/O QoS
- reconstruct space_maps
- convert AVL trees to B-trees or hash tables
- large dnodes
- cross platform xattr
- use refcount_t for v_count
