  • Your name, logo, and link on the announcement email (if possible)
  • Mentioned as a thank you during the opening and closing of the event
  • Space to put your pop-up banner at the event
  • An opportunity to be known as a OpenZFS supporter in a very talented and influential community

Funded items

Please send email to admin at open-zfs dot org if you would like to sponsor the event.

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
  • One man page per subcommand
  • Channel Programs - continuation of work from last year's hackathon
  • 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?)
  • 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)
