ZFS On-Disk Specification – Draft (ZFSOnDiskFormat.pdf, Sun Microsystems, Inc., 2006-08)

  • sometimes known as the ZFS On-Disk Format document
  • a good overview, but sorely outdated.

Examining ZFS On-Disk Format Using mdb and zdb (2008-06-28)

  • a forty-three minute video of Max Bruning presenting to the OpenSolaris Developer Conference in Prague.

The source tour (archive) describes the various subcomponents in ZFS.

Repo-specific developer documentation

  • Illumos integration process
  • Information about how to develop ZFS for the different distributions/pointers to them (e.g., how to build illumos)
    • in particular, documentation about how to test and possibly scripts for building
    • needs to be written/links provided by reps from those communities.
