The future of OpenZFS and FreeBSD

Looking at the recent changes to the OpenZFS Project, and how FreeBSD will interact with the OpenZFS Project going forward. This talk will discuss: How the OpenZFS project started How the OpenZFS project has changed over the last 5 years The introduction of the monthly ZFS Leadership Call New problems as ZFS has matured (needing to add a deprecation policy, etc) How the OpenZFS project is working to reduce the differences across platforms (command line switches, NFS differences) Interoperability improvements (feature flag ‘compatibility’ groups) New procedures to prevent divergence and coordinate development across platforms (reserving flags, wider discussion before names for features/flags are decided) Then switch gears and cover FreeBSD specific issues: The switch to ZoL as upstream Why we are making the change What we get out of it How it is better for all of OpenZFS And finally a status report: ZFS-on-Linux and ZFS-on-FreeBSD are now “OpenZFS” There is no LinuxKPI in ZFS (kill the FUD) What has OpenZFS done for me lately (new and upcoming features) Allan Jude FreeBSD user (2001), doc (2014), and src (2015) committer.
