OpenZFS Developer Summit and Hackathon
Karyn Ritter and I organized, and Delphix hosted the first OpenZFS Developer Summit last week. The two-day event consisted of prepared talks & collaborative discussions on Monday, and a hackathon on Tuesday. We had 30+ participants including 15 speakers.
The event was funded by the sponsorship of 10 companies (including Delphix). The most lively discussions centered around a platform-independent OpenZFS code repository. Other talks included the storage tiering work that Nexenta has done, a new channel-program based administrative API for ZFS, and several talks on performance and testing. 20+ people participated at the hackathon, where 9 projects were started.
One of the main goals of the hackathon was to get people from different communities working together on the code -- a goal that we handily achieved, with about half the teams composed of people who had not met each other before this event. Several projects were nearly completed, including: ZFS send progress monitoring via ps and top; 1MB block size; more dedicated kmem_caches; and compressed ARC.
The participant's choice award for best hackathon project went to a team of 5 lead by John Kennedy that worked on getting the Testrunner ZFS test suite running on Linux, FreeBSD, and in userland on illumos.
