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- a good overview, but sorely outdated.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 describes the various subcomponents in ZFS.
Blog posts on specific ZFS features:
- snapshots
- scrub/resilver
- ZIL (ZFS Intent Log)
- space maps and block allocation
- hot spares
- deduplication
- RAID-Z
- L2ARC
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.
